San Francisco’s weather has always been unpredictable, and this week is no exception. Mornings will start off cool and crisp, but don’t be fooled—by the afternoon, temperatures will climb to nearly spring-like levels. If you’re heading out, you’ll want to dress in layers, because what feels like winter in the morning will start to feel like spring by lunchtime.
With minimal rain expected, this week is shaping up to be dry, but that doesn’t mean it will be consistent. Here’s a detailed breakdown of what’s ahead.
Current Conditions: Chilly Start to the Weekend
Right now, San Francisco is waking up to partly cloudy skies and a cool 50°F (10°C). If you’re stepping outside early, a light jacket or sweater is a good idea, especially with the slight morning breeze making it feel even colder.
But don’t let the cool morning fool you—by the afternoon, temperatures will rise significantly. The city will warm up under the afternoon sun, making for a comfortable day overall.
Weekend Forecast: Sun and Clouds with Noticeable Warm-Ups
- Saturday: Expect a mix of sun and clouds throughout the day, with temperatures climbing to a comfortable 62°F (17°C). At night, things cool down again, dropping to 48°F (9°C), so if you’re heading out in the evening, bring an extra layer.
- Sunday: Morning fog and clouds will gradually clear by the afternoon, bringing temperatures up to 62°F (16°C). Nights will stay a bit milder, hovering around 51°F (10°C).
Next Week: A Gradual Warm-Up with More Sunshine
As we move into the week, San Francisco’s weather will become more stable, but still unpredictable enough to keep you on your toes. Here’s what you can expect day by day:
- Monday: The city will see a good amount of cloud cover, keeping temperatures around 60°F (15°C) during the day and 52°F (11°C) at night.
- Tuesday: Skies will begin to clear up, and temperatures will warm to 63°F (17°C). The evening will cool down slightly to 50°F (10°C).
- Wednesday: The warmest day of the week! Expect mostly sunny skies with temperatures peaking at 69°F (20°C). Even nighttime temperatures will remain relatively comfortable at 51°F (10°C).
- Thursday: Partly sunny with daytime highs of 62°F (17°C) and a mild night at 54°F (12°C).
Why Is San Francisco’s Weather So Unpredictable?
San Francisco’s weather is shaped by its unique geography. The city is surrounded by the Pacific Ocean, which brings in cool air and fog, especially in the mornings. As the sun comes up, that fog burns off, allowing temperatures to rise in the afternoon.
Another major factor is the Bay Area’s microclimates. It could be cold and foggy near the Golden Gate Bridge, but just a few miles away in neighborhoods like the Mission District, it might be sunny and warm. This is why the city often experiences dramatic temperature swings within just a few hours.
How to Prepare for This Week’s Weather
- Dress in Layers: Mornings will start off cool, but you might be shedding layers by the afternoon. A light jacket or sweater will be useful early in the day, but you might not need it by lunchtime.
- Expect Some Fog: Mornings may be cloudy or foggy, especially near the coast. This will clear up as the sun comes out.
- Enjoy the Dry Weather: Unlike many other parts of the country experiencing winter storms, San Francisco will stay mostly dry, with no major rain expected this week.
Bottom Line: It’s Classic San Francisco Weather—Unpredictable but Beautiful
San Francisco is known for its dramatic shifts in weather, and this week is a perfect example. Mornings will start out chilly and cloudy, but by the afternoon, the sun will break through, and temperatures will feel much warmer.
Whether you’re heading to work, exploring the city, or planning a weekend outing, just remember: dress in layers, be prepared for changing conditions, and enjoy the mild, dry weather ahead
