San Jacinto Forecast
Tuesday, May 5, 2026

The weather this afternoon in San Jacinto will stay mostly cloudy with a slight chance of a shower through about 5 PM, but any rain that does develop should be brief and light. Temperatures will top out near 62°, with a west wind around 5 mph to 10 mph. Tonight stays mostly cloudy and cool, with a low around 47° and a light southwest breeze. It will be a quiet evening for outdoor plans, though you may still want a light jacket if you're out late.

Tomorrow brings a much nicer setup, with sunny skies and a warmer afternoon near 77°. A southwest wind around 10 mph could gust as high as 20 mph at times, so it will feel breezy, especially during the afternoon. Looking ahead through the week, sunshine dominates and temperatures climb quickly: near 88° Thursday, around 90° Friday, about 92° Saturday, then hotter still with 96° Sunday and near 99° Monday. This will be a great stretch for dry weather, but the heat will become the main concern by the weekend and early next week, so plan for more water, shade, and extra caution during the hottest part of the day.
