Essentials for San Francisco in March
Waterproof and Windproof Jacket
San Francisco is famous for its sudden weather changes, and a good jacket will protect you from unexpected rain showers and the often-strong winds, especially near the coast.
Warm Scarf
A scarf is incredibly versatile for combating the chilly breezes and adding an extra layer of warmth around your neck, a common complaint for visitors.
Comfortable Walking Shoes
You'll be doing a lot of walking up and down San Francisco's famous hills, so supportive and broken-in shoes are an absolute must.
Layering Sweaters or Cardigans
These are perfect for adding warmth under your jacket or for wearing on their own during milder periods, allowing you to adapt to changing temperatures.
Lightweight Umbrella
While your jacket might be waterproof, a compact umbrella is handy for persistent rain, keeping you drier and more comfortable.
Beanie or Warm Hat
When the wind picks up or the fog is thick, a hat can make a huge difference in keeping you warm and comfortable.
Crossbody Bag or Small Backpack
Ideal for carrying your layers, water bottle, and essentials securely while keeping your hands free for exploring and snapping photos.
Portable Power Bank
Perfect for keeping your phone charged while navigating with maps, taking photos, and staying connected throughout your long days of exploration.
Reusable Water Bottle
Stay hydrated as you explore the city's hills and sights, and reduce plastic waste with San Francisco's many refill stations.
Blister Treatment/Band-Aids
With all the walking you'll be doing, it's wise to be prepared for any foot discomfort, ensuring your adventures aren't cut short.
Pro tips
Public Transportation is Your Friend
While walking is great, San Francisco's hills are no joke. Utilize Muni buses, streetcars, and cable cars to save your legs, especially after a long day of sightseeing.
Book Alcatraz in Advance
If visiting Alcatraz is on your agenda, book tickets weeks (or even months) in advance, as they sell out quickly, especially in March.
Dinner Reservations are Recommended
San Francisco is a foodie paradise. If you have specific restaurants in mind, especially popular ones, make reservations before you go.
Explore Beyond the Tourist Spots
While the Golden Gate Bridge and Fisherman's Wharf are must-sees, venture into neighborhoods like The Mission, North Beach, or the Castro for a more authentic local experience.
