Excelsior District Weather
Town • San Francisco Bay Area
The Excelsior spreads over the southern part of San Francisco between I-280 and McLaren Park, with Mission Street as its crowded commercial spine. Its streets are named for world cities and countries, from Paris and London to Russia and Madrid. Rows of houses climb east from Mission Street up the slope of the McLaren Park ridge. Excelsior Playground sits near the middle of the district, and Crocker Amazon Playground and the Balboa Park BART station sit near its southern and western edges. It is a residential district first, close to the county line and to Daly City.

The Excelsior is south of the San Miguel Hills rather than behind them. Weather Service climatologists describe the summer sea breeze squeezing through low points in the coastal hills. The lower country between Mount Davidson and San Bruno Mountain, through Daly City and along the I-280 corridor, is one of those breaks. On many summer afternoons, fog and wind reach the Excelsior from the southwest sooner than the Mission or Bernal Heights. Those neighborhoods sit sheltered behind bigger hills.

What shapes Excelsior District's weather
The Excelsior sits about four miles from the ocean, on the bay side of the city's hills. The Weather Service notes that summer morning overcast clears more fully on the bay side than near the ocean. Even so, the Excelsior's summer mornings are often gray, and in July the fog often lingers into the afternoon. It stays grayer than the Bayview farther east, which sits more sheltered from the gap.
Height on the slope matters within the district. The blocks near Mission Street sit lower and are a bit more protected. The upper streets climbing toward McLaren Park get the views and the full force of the afternoon westerly.
Tips for visiting Excelsior District
Pack a layer for summer afternoons
A sunny morning here can turn breezy and gray once the fog rolls in from Daly City. Bring a warm layer and a windbreaker, even though this is one of the city's sunnier districts.
Take BART to Balboa Park
The station at 401 Geneva Avenue has no parking, so plan on arriving by transit, bike, or on foot.
Play under the lights at Crocker Amazon
The playground is a full sports complex with five lighted soccer fields, plus baseball, tennis, basketball, and bocce courts.
Bring small kids to Excelsior Playground
At Russia Avenue and Madrid Street, it has a children's play area, a baseball diamond, and tennis and basketball courts. The park is open 5 a.m. to midnight.
Walk up into McLaren Park
McLaren's trail network connects to University Street on the park's west side, putting miles of trails close to the Excelsior.
Excelsior District through the seasons
- Spring (March–May)
- Spring mixes the last showers of March with breezy, partly cloudy days, and the afternoon wind builds through May.
- Summer (June–August)
- Summer mornings are often gray, and in July the fog can hang on all day. A stiff westerly blows in most afternoons through the low ground toward Daly City.
- Fall (September–October)
- Fall heat waves are the exception to the breezy pattern, bringing the year's warmest, stillest days.
- Winter (November–February)
- Storms from November through March bring most of the year's rain, with clear, chilly days between them.
Activities and the weather that matters
- Soccer and field sports at Crocker Amazon: The lighted fields are used year-round. Mornings are calmest, and summer afternoons bring wind.
- Eating along Mission Street: Mission Street's restaurants work in any weather and make a good plan on gray, breezy summer evenings.
- Hiking McLaren Park: Go on clear mornings, because the ridge is exposed to the afternoon westerly.
