We like the City by the Bay best in April and October. When is your favorite time to go to San Francisco?

| November December January |
This is the rainy season. Monthly rainfall often comes all on the same day, especially during winter storms. Californians feel very cold on days when people from other parts of the country think it's warm. Please don't laugh, we can't help it! The day after it rains, the skies are sometimes exceptionally clear. |
Umbrella or rain jacket with hood Warm jacket (not a heavy winter coat) Long-sleeved shirts and sweaters Light gloves |
| February March |
In some
years, winter rains extend into these months. In others it's reasonably
dry. Spring-blooming trees and flowers are at their best. |
Mid-weight jacket Long-sleeved shirts and sweaters to wear in layers |
| April May |
Clear
days and little fog. One of the best times of year to visit. |
Mid-weight
jacket Short-sleeved shirts and light weight pants, sweater for layering Shorts on the warmest days, but it may be too cool |
| June July August |
Warm days. Evening fog comes in suddenly and can be extremely cold. |
Shorts
for daytime (warmest days) Jacket or sweatshirt and long pants for evenings |
| September October |
Clear
days and little fog. One of the best times of year. |
Mid-weight
jacket Short-sleeved shirts and light weight pants, sweater for layering Shorts on the warmest days, but it may be too cool |
When I say it's cold on June and July evenings, I mean it. The fog is wet, and creates a cold, damp wind as it comes in, making Fourth of July night sometimes colder than New Year's Eve. To watch San Francisco's Fourth of July fireworks, I wear warm pants and take 3 to 4 layers of long-sleeved shirts and/or sweatshirts. If you aren't prepared with proper clothing, you will most likely be improving the local economy by purchasing warmer clothes from a street vendor.
