San Francisco Weather Forecast: June 16-22, 2024

San Francisco residents can expect mild, mostly sunny conditions through the week of June 16, with temperatures ranging from 55 to 72 degrees Fahrenheit, according to the National Weather Service (NWS). Winds will remain consistent, blowing from the west-southwest at speeds between 3 and 14 mph, with minimal precipitation risk across the region.

What is the weather outlook for San Francisco this week?

The NWS reports stable weather patterns for the Bay Area through June 22. Tuesday, June 16, serves as the baseline for the week, with temperatures peaking at 70 degrees during the day and dropping to 56 degrees at night. Skies are expected to be mostly sunny, maintaining a 0% probability of precipitation. This trend of clear mornings and partly cloudy evenings continues through the upcoming weekend.

Pro Tip: Coastal microclimates in San Francisco often cause temperatures to drop rapidly once the sun sets. Even on clear days, keep a light layer handy for the evening transition to 55-degree lows.

How do temperatures fluctuate throughout the week?

Data provided by the NWS indicates a narrow temperature band for the city. Wednesday, June 17, is projected to be the warmest day of the period, reaching 72 degrees. Conversely, the week concludes with cooler overnight lows, settling at 55 degrees between June 21 and June 22. Wind patterns remain predominantly west-southwesterly, which typically helps regulate San Francisco’s air quality and temperature, preventing extreme heat spikes common in inland California.

Why does the coastal wind influence local conditions?

The consistent wind speeds, ranging from 3 to 14 mph, act as a natural air conditioning system for the peninsula. According to the NWS, the prevailing west-southwest direction brings cooler maritime air inland. This explains why, even as inland valleys may experience higher heat, San Francisco maintains its moderate 60s and 70s range. The low probability of precipitation—peaking at only 6% on June 19—highlights a stable, dry period for the city.
