Downtown San Francisco Weather

Town • San Francisco Bay Area

Downtown takes in the Financial District's towers and the Union Square shopping blocks. It stretches from Market Street north toward Chinatown and east to the Embarcadero and the Ferry Building. It is the city's densest cluster of high-rises, with cable car turntables, the Central Subway, and the Market Street transit spine meeting here. Downtown sits on the bay side of the city, screened from the ocean by Nob Hill and Pacific Heights, so it runs sunnier than the west side. Its towers also stir up gusts at street level that the open hills around it don't get.

What shapes Downtown San Francisco's weather

Downtown's towers make their own weather at street level. When the westerly sea breeze from the ocean runs into tall buildings, part of it is pulled down to the sidewalk and squeezed through the gaps between them. Certain corners along Market Street and the plazas near the Embarcadero can be gusty on an otherwise moderate day, while a block away the air is still. Tall walls also keep narrow streets in shade for much of the day, so a sunny forecast can still mean a cold walk between buildings.

The Embarcadero edge is exposed to wind and chop off the open bay. On the city's occasional hot days, usually in September and October when offshore winds shut off the sea breeze, pavement and stone hold heat into the evening. Winter storms bring rain and gusty south winds that whip around the high-rises.

Tips for visiting Downtown San Francisco

  • Buy cable car fares before Powell and Market

    Boarding at the Powell and Market turntable requires advance purchase from 8 a.m. to 8 p.m. MuniMobile or Clipper lets you skip the ticket line.

  • Take the Central Subway to Union Square

    The T Third line's Union Square/Market Street station links downtown with Chinatown to the north and SoMa and the 4th Street Caltrain station to the south.

  • Pick sunny sidewalks on cool days

    Around midday the sun shines straight down the north-south streets, so walk those on a cool day. Narrow east-west streets between towers sit in the shadow of the buildings on their south side.

  • Hold on to hats at tower corners

    On breezy afternoons, expect sudden gusts at the tower corners along Market Street and in the Embarcadero plazas. A block away, the air can be still.

Downtown San Francisco through the seasons

Spring (March–May)
Spring brings clear, cool days, with afternoon breezes around the towers that are strongest in April and May.
Summer (June–August)
Summer is often sunnier here than on the west side, but cool and breezy in the shade of high-rises. Fog can drift in over the hills by evening.
Fall (September–October)
September and October bring the warmest weeks of the year, the best time for sitting out in the plazas and on waterfront benches.
Winter (November–February)
Storm winds gust hardest at tower corners and along the open Embarcadero, and rain makes the Market Street crossings messy.

Activities and the weather that matters

  • Shopping around Union Square: This works in any weather. On rainy days, stores and transit stations are close together.
  • Walking the Embarcadero to the Ferry Building: The walk is best on calm, clear mornings or fall afternoons. Summer afternoons bring a cool wind off the bay.
  • Riding the cable cars: The Powell lines start at Powell and Market and the California line at California and Market. Sunny days are best for the open running boards.
