1. Pack for Microclimates (Yes, Even in July)

Let me say this loud for the people in the back: San Francisco is cold in the summer. While the rest of California is sunbathing, SF is rocking 60°F, cloudy mornings, and windy afternoons thanks to the infamous marine layer. Learn more about what to pack for San Francisco.

What to bring:

A lightweight jacket (even in summer)
A scarf or sweatshirt for layering
Comfortable walking shoes (those hills are no joke)
Sunglasses and sunscreen – because the sun will surprise you in the afternoon

2. Public Transportation is a Vibe (But a Quirky One)

The Muni system (bus + light rail) will get you where you need to go, but it’s not always straightforward. Cable cars are fun for the ‘gram, but expensive for daily travel. Instead, get a Clipper Card, which works on all forms of public transit.

Tips to get around smarter:

Avoid rush hour if you can (locals are commuting, not sightseeing)
Use the MuniMobile app or Google Maps to track buses and trains in real time
Walk when possible – some of the best views are at street level!

3. The Fog Has a Name—And a Schedule

Meet Karl the Fog. Yes, he has a name. Yes, he has an Instagram. And yes, he will photobomb your Golden Gate Bridge shot.

Fog pro tips:

Morning fog usually burns off by late morning, especially in summer
Best times for clear skies: September and October (aka San Francisco’s real summer)
Don’t wait until the last day of your trip to try and get that bridge pic—fog is fickle!

📸 For clearer weather and fewer crowds, consider a fall visit. And yes, you’ll still need that jacket.

4. Book Alcatraz in Advance—Especially for Night Tours

Alcatraz is not one of those places you just show up to. Tickets can sell out weeks ahead, especially for the hauntingly cool Alcatraz Night Tour.

🔗 I always recommend grabbing your Alcatraz tickets here early—you won’t regret it.

5. San Francisco is Smaller Than You Think

The city covers only 49 square miles, which means you can technically see a lot in one weekend. But with all the hills and neighborhoods to explore, you’ll want to pace yourself.

Don’t miss:

The Mission for murals and burritos
North Beach for Italian food (try Cotogna – we went twice!)
Haight-Ashbury for vintage shops and tie-dye vibes
The Marina for waterfront strolls and pastel houses

Tipping: Standard U.S. tipping rules apply—think 15–20% at restaurants, $1–2 per drink at bars, and $1–5 for hotel staff or drivers.

Safety: Like any city, SF has areas you’ll want to avoid at night. Stay alert in neighborhoods like the Tenderloin, especially after dark.
