Wednesday’s Cooler Conditions Before the Turnaround
Wednesday will continue the unsettled pattern with rain likely throughout the day. Highs will struggle to reach the low 60s, making it a notably cooler day. This mild system is part of a broader pattern shift that has ended San Francisco’s record-breaking warm and dry March.
By Thursday morning, the rain exits and skies begin to clear. It’s a brief respite period before a dramatic warming trend takes over the region. The transition from cool and wet to warm and dry happens fast, making this an ideal time for people to prepare summer gear.
Friday Marks the Start of Impressive Warming
| Day | Forecast | High/Low |
| Friday, April 4 | Sunny, clearing trend begins | 65°/52° |
| Saturday, April 5 | Mostly sunny, warming accelerates | 69°/51° |
| Sunday, April 6 | Partly cloudy to sunny | 70°/52° |
| Beyond | Continued warming into next week | TBA |
The warming trend is significant, with meteorologists noting it will be pretty notable. High pressure builds into the region, pushing out storm systems entirely and ushering in sunny skies. Weekend temperatures will reach the upper 60s to low 70s, representing a 10-15 degree jump from midweek readings.
“The rain and cooler weather will not last long. We get another warming trend through the weekend.”

Why This Pattern Matters for Your Weekend Plans
After San Francisco’s record-setting March with temperatures 20-30 degrees above normal, this week’s rain provides relief and resets the seasonal outlook. The brief cooling is typical spring behavior, allowing soil moisture recovery and preventing extreme fire danger.
The rapid shift to warmer conditions starting Friday positions the region perfectly for outdoor activities. Plan indoor or umbrella-friendly events for today through Thursday, then embrace the sunshine over the weekend. This pattern also suggests April and May will feature warmer-than-average temperatures with below-normal rainfall, making it prime time for hiking, beach visits, and outdoor dining.
