When packing for a trip to San Francisco be prepared for changing temperatures.
As a heavy fog rolls in through the Golden Gate a summer day may feel more like winter,
but that's just part of San Francisco's charm.
Winter · Mornings and evenings tend to be chilly. A warm
overcoat and sweater are appropriate attire. The Bay Area sees most of its
rainfall in the winter months which makes packing an umbrella a good idea.
Spring · The spring months in San Francisco are true to season.
Linen and cotton clothing is ideal, however, pack a sweater or medium-weight
jacket for likely temperature changes. In the spring, the flowers are in
bloom and those prone to allergies should pack necessary medication.
Summer · Legend has it that Mark Twain once said the coldest
winter he ever spent was a summer in San Francisco. Chilling morning and
evening fog is common during summer months. Bring a sweater or a medium-weight
jacket. You may encounter cool temperatures during a day on the bay, at
Alcatraz or walking the bridge. Evenings are typically cool. Women should
pack a blazer or dressy coat for a night out. Men will be comfortable in
a sports jacket and long pants.
Note: If you intend to travel to neighboring counties north (Marin or
Napa) or south (San Jose to Santa Cruz), pack typical summer clothing such
as shorts and T-shirts.
Fall · The City sees its best weather in the fall from September
to October. Temperatures are known to rise into the 70s and 80s, a "heat
wave" by San Francisco standards. Remember that the bay is breezy and
a medium-weight jacket is always a good idea whatever time of year you choose
to visit.
