April is one of the best months to visit San Francisco. Rain is unlikely, and summer fog won't arrive for a few more weeks. That leaves nothing but sunny days to explore the city.

That would be enough all by itself, but April is between spring break and summer vacation, making it a great time to enjoy San Francisco tourist attractions without all the crowds.

What to Pack

April is often warm enough at mid-day that you can get by with a couple of layers, but you'll need a bit more for evenings. It might seem a little early in the year for this, but April often has the sunniest days. Hats and sunscreen may be welcome.

San Francisco is a casual city. You can wear jeans or casual clothing almost everywhere you go. Bring a jacket for cooler nights, but you probably won't need your earmuffs and wool mittens — although you may see some cold-blooded locals bundled up like they were at the North Pole.

You probably won't need an umbrella, but if it's windy, you'll be glad you packed that scarf and hooded jacket. And even if this sounds odd, pack sunscreen and sunglasses. When the UV Index (amount of skin-damaging radiation) exceeds 6 to 7, you need both skin and eye protection.
