San Francisco is one of the most dynamic cities on the West Coast. From the iconic Alcatraz Island to the sloping streets of Lombard, it offers diverse experiences and equally diverse weather—often all in one day. As a San Franciscan and full-time travel blogger, I've learned how critical it is to pack strategically for a trip to the San Francisco Bay Area. Whether you're exploring the South Bay, heading to Fisherman’s Wharf, or flying into San Francisco International Airport, this San Francisco packing list will ensure you're prepared for every microclimate and every adventure.
TL;DR: Your San Francisco Packing List at a Glance
San Francisco's weather changes by neighborhood and hour. Whether you’re heading to Ocean Beach, working remotely from a Ferry Building cafe, or attending meetings in SoMa, layering is key. This packing list includes everything from rain boots and a light jacket to business casual pieces that transition seamlessly.
Must-Haves:
- Comfortable walking shoes
- Light jacket or windbreaker
- Waterproof layers
- Packable umbrella
- Smart casual outfit
- Layers for fluctuating temperatures
Why San Francisco Travel Requires a Unique Packing Strategy
The City by the Bay is famous for its ever-present fog—aka Karl the Fog (yes, the fog has a name)—and its wild microclimates. Sunshine in the Mission can turn into mist in the Sunset District or gusty winds by City Hall. If you’re heading from San Diego or San Jose, be prepared: San Francisco doesn’t follow California’s sunny stereotype.
Always pack for wind, fog, and cool temperatures—even in summer. Dressing in layers is essential to blend in with San Francisco locals and to stay comfortable.
Seasonal Packing Recommendations for San Francisco
As we mentioned, the most important thing when packing your day bag is never to be caught off guard by Karl ... the Fog.
No matter what season you visit San Fran, always think layers!
Spring (March - May): Cherry Blossoms & Fog Banks
Spring is when the city slowly starts to break free of the winter haze. Cherry blossoms bloom in Japantown, and the days begin to stretch just long enough to fit in a sunset after dinner (I suggest Lands End Lookout for the photography enthusiasts out there).
Typical Weather:
Temperatures typically range from 50°F to 65°F, and while March typically brings showers, April and May tend to be drier and sunnier... though Karl the Fog still likes to drop by at some point most days.
Microclimates are also very real here; there can be sunshine in the Mission District, mist in the Sunset District, and brutal winds in the Marina all within the same afternoon. Even when it is sunny, understand that “sunny” this time of year can mean standing in bright light with goosebumps.
What to Pack:
- A windproof, water-resistant jacket (a trench coat works too - locals love a little flair)
- Layerable pieces like long-sleeve tees, cardigans, and lightweight sweaters
- One warm layer, like a fleece or merino wool sweater, for evenings
- Comfortable walking shoes (I recommend something supportive and closed-toe - those hills are no joke)
- A compact umbrella (you can check to see if your hotel offers them to save packing space, but the ones they offer are often large and bulky)
Spring also brings a handful of unique city happenings. The Northern California Cherry Blossom Festival takes over Japantown in April, featuring cultural performances and vibrant food stalls. May’s Bay to Breakers is one of San Francisco's most heralded and quirkiest traditions, where runners “compete” in a footrace wearing costumes (or sometimes a shocking lack thereof).
For city explorations, I always pack a “smart casual” outfit that allows me to go straight from meetings to local haunts without feeling over- or under-dressed.
Most importantly, always always always pack layers!
Summer (June – August): The Coldest "Winter"
Despite being peak travel season, summer in San Francisco is famously misleading. While much of the country basks in sweltering heat, SF locals are pulling on fleece jackets and wading through fog banks.
Typical Weather:
Temperatures in June and July are typically cool for summer months, averaging between 55°F to 68°F. August warms up slightly, but be warned, the ocean wind off the Pacific can cut right through light clothing!
Mark Twain is famous for having (debatably) said, “The coldest winter I ever spent was a summer in San Francisco.” Whether he did or didn’t, any of us who have packed beach clothes for a July visit can sympathize with the sentiment.
What to Pack:
- A warm, packable fleece or down vest
- Windbreaker or light jacket (preferably insulated and waterproof)
- Long pants and midweight tops (you likely won’t need shorts unless heading out of the city)
- Waterproof shoes
- Closed-toe shoes for walking
-
Layering-friendly outfits for day-to-night transitions
Despite the cool air, summer in San Francisco is alive with energy. The San Francisco Pride Parade in June is one of the largest and most spirited events in the world, drawing thousands in dazzling displays of color and inclusion. August brings Outside Lands Music Festival to Golden Gate Park, where live music, gourmet food, and layers of fog all come together in perfect harmony.
Pack a comfortable, smart-casual outfit for dining out. Think nice jeans, stylish top, and a sharp jacket. Restaurants in neighborhoods like the Mission or North Beach tend to lean effortlessly hip, and dressing in layers will ensure you’re ready for both a warm, sunny lunch and a brisk evening dinner.
Forget the sundresses and flip-flops. Summer in San Francisco is more about cozy sophistication than poolside lounging.
Fall (September – November): The City's Secret Summer
When is the best time to visit San Francisco? Here’s the secret most people don’t realise: fall is the best time to visit San Francisco!
Typical Weather:
September and October are the city’s warmest, sunniest months and are often referred to as “San Francisco summer.” Skies are clear, winds mellow out, and temperatures finally rise into the 65°F to 75°F range.
By November, things start to cool and gray a bit, with averages dipping back down to the high 50s.
What to Pack:
- Lightweight layers for the day: t-shirts, breathable long-sleeved shirts, and light sweaters
- One warmer layer, like a fleece or wool cardigan, for cool evenings
- Sunglasses and sunscreen (yay!)
- Comfortable walking shoes (it may be warm enough for flip-flops, but city hills still exist)
- A fashionable jacket for layering, especially if you’ll be out after dark
In addition to great weather, Fall is also packed with great events. September's Folsom Street Fair showcases the city’s bold and eclectic spirit (definitely NSFW, but a cultural experience like no other). In October, the Hardly Strictly Bluegrass Festival is a free, three-day music celebration in Golden Gate Park that requires nothing more than a blanket to sit on.
This is also a great time to explore wine country, time permitting. Napa and Sonoma are just a day trip away and are in full harvest mode. I often bring a daypack with just enough room for a change of shoes and a bottle of wine or two (thank you, expandable Knack Pack!).
Despite the warm days, evenings still get cool. Plan to bring a slightly elevated outfit, such as a button-up and blazer or a midi dress with boots.
Winter (December – February): Rainy But Not Frozen
The bad news is that winter in San Francisco is all about damp sidewalks and moody skies. The good news is that there is seldom snow and ice.
Typical Weather:
Average temperatures hover between 48°F and 60°F, and while it rarely drops below freezing, this is the city's rainiest season. That said, sunny days are not unheard of! Just be prepared to bundle up even if the sun is out.
An important note is that winter rain in San Francisco tends to come in short bursts. Even if it is sunny when you leave your hotel, it is worth taking a compact umbrella with you if you will be outside much!
What to Pack:
- A waterproof jacket or shell with a hood (or a stylish trench with water resistance)
- Warm mid-layers, like merino wool sweaters or fleeces
- Sturdy waterproof shoes or boots for puddle-hopping
- Compact umbrella (hotels may provide one, but they are often large and bulky)
-
A scarf and a warm hat for early mornings and breezy afternoons
Winter is a fantastic time to explore the city's cultural side. The Chinese New Year Parade, usually held in late January or early February, is one of the largest outside Asia, complete with lion dancers, firecrackers, and a 200-foot-long Golden Dragon winding through Chinatown. December’s Illuminate SF Festival of Light transforms public spaces into glowing, interactive art installations across the city.
If you're museum-hopping (highly recommended during rainy days), layer up. The de Young Museum in Golden Gate Park and the Exploratorium along the waterfront are two favorites, but both tend to keep the indoor temps on the chilly side.
Restaurants stay busy this time of year, so bring a slightly nicer outfit for dinner out. I personally always carry a small shoe bag in my backpack so I can swap out comfortable walking shoes for dress shoes when alternating between work and exploration.
Winter weather in San Francisco doesn’t stop the city from moving, but it does reward the well-prepared. With smart layers and waterproof staples, you’ll stay cozy and dry while still looking professional.
Organization and Packing Tips for Your Trip to San Francisco
Mastering San Francisco means mastering layers and organization. It’s visiting places like this that turned me into a #OneBagLife convert.
Being able to fit everything you need into your carry-on and personal item for the flight, then scaling down to just a backpack for day trips, requires some serious strategy. Here’s how I approach it:
-
Master the Layer Game with Packing Cubes
San Francisco’s microclimates mean you’ll need a variety of layers, but that doesn’t mean your suitcase has to be a disaster. I use Knack’s packing cubes to separate tops, bottoms, and layers by weight. Once I’ve arrived, I use them to keep a change of clothes with me that stays clean and pressed for when the work day is done. -
Choose a Versatile Bag That Handles Business and Leisure
Whether I’m heading to a café in the Castro or a client meeting downtown, I value a bag that can transition seamlessly between casual and professional. The Knack Series 2 Expandable Backpack is the best I have found… seriously! It expands for weekend trips, compresses for city strolls, keeps my laptop safe, and is extremely comfortable, all without sacrificing style. Plus, it counts as a “personal item” on flights rather than a carry-on! -
Bring a Shoe Bag (Seriously)
San Francisco is a pedestrian city at heart, so walking is a huge part of any trip. You will often need two pairs of shoes on a day out: waterproof sneakers (or boots) for exploring and something professional for meetings or business dinners. A dedicated shoe bag keeps your clothes clean, dry, and helps your pack stay organized. -
Don’t Overpack, Just Pack Smart
You don’t need a new outfit for every microclimate. Stick to a color palette (navy, grey, and/or blacks are my go-to), and build around staple pieces that layer well. One pair of jeans, a pair of joggers, a few tops, a fleece or merino sweater, and a rain shell can take you just about anywhere in the city. -
Create a Tech Kit
San Francisco is a digital nomad mecca. The ample co-work spaces, coffee shops, and casual restaurants make it easy to find a new home office every day. I recommend utilizing a tech organizer to keep chargers and electronics dry and neatly organized on the go.
Tips for Business Travellers in San Francisco
Whether you’re in San Francisco for a conference, client meetings, vacation, or remote work between sightseeing, the city offers plenty of resources to keep you productive, comfortable, and well-fed.
As someone who’s worked remotely from dozens of cities around the world, I find San Francisco to be especially business-travel friendly as long as you know where to go.

Frequently Asked Questions
How should I dress for San Francisco?
Whether business or casual, think layered chic when visiting San Francisco. Always have something warm and something water-resistant available, even in the summer. The biggest mistake visitors make is assuming that California equals hot weather when, in reality, San Francisco’s famous fog can roll in unexpectedly and drop temperatures by 10-15 degrees.
How do I prepare for a trip to San Francisco?
- Pack smart: Choose versatile clothing you can layer throughout the day. Refer to the seasonal section of this guide for specifics.
-
Reserve early: Hotels and restaurants fill up quickly, especially around major events like Pride (June) or the Chinese New Year Parade (January/February).
-
Embrace the microclimates: The weather can vary wildly from one neighborhood to the next. Bring a bag that can carry your day’s layers, like a Knack expandable backpack.
- Get a transit pass: If you plan to use public transportation, load a Clipper Card to your Apple Wallet or Google Pay to make riding Muni and BART a breeze.
Check the fog forecast: Download a fog forecast app like Karl Weather (Apple App Store, Google Play Store), follow Karl the Fog on X, or check local microclimate maps.
What’s public transit like in San Francisco?
San Francisco’s Muni system (buses, light rail, and historic streetcars) covers most of the city and is generally reliable, though not always speedy. BART (Bay Area Rapid Transit) connects San Francisco with the East Bay and SFO Airport, making it ideal for commuters and travelers.
The cable car provides an iconic, scenic, and functional option for getting up those steep hills... Just be prepared to wait if you’re near a tourist-heavy stop like Powell Street.
Save money and avoid having to carry a travel pass by adding a Clipper transit card to your Apple Wallet or Google Pay. This is the Bay Area’s all-in-one transit card and allows contactless transport payments throughout the region.
What’s traffic and rush hour like?
Traffic can be intense, especially during weekday rush hours (7:00–9:30 AM and 4:00–6:30 PM). The narrow, hilly streets and frequent construction zones don’t help. Parking is also notoriously difficult and expensive.
Unless you need to leave the city often, you’ll be better off without a car. Use rideshares, public transit, or simply walk; the city’s layout rewards pedestrians with beautiful views and quirky finds.
Is San Francisco safe for solo travelers?
Despite significant media attention suggesting otherwise, San Francisco is a perfectly safe destination with the usual big-city caveats. Most tourist-friendly areas like North Beach, Marina, Castro, and Haight-Ashbury are quite safe, however, there are areas like Tenderloin and SoMa that can feel less comfortable, especially after dark.
Petty theft is the most common issue. Never leave valuables in your vehicle, even for a minute, and secure backpack zippers when commuting through crowded places.
Stay aware, trust your instincts, and don’t hesitate to ask locals for advice. San Franciscans are generally friendly, opinionated, and happy to point you toward their favorite taqueria or coffee shop.
Conclusion
San Francisco is a city of beautiful contradictions: sunshine and fog, startups and sourdough, tech hubs and Victorian homes. Packing for a place this dynamic can be tricky, but with thoughtful planning and smart organization, you’ll be ready for whatever the city throws your way!
Remember: layering is your best friend, and comfort never goes out of style when you’re climbing steep hills or braving chilly ocean breezes. From strolling the Embarcadero to grabbing a latte between meetings in SoMa, having the right gear makes every experience smoother and more enjoyable.
Happy travels, and may Karl the Fog treat you kindly!
