Sacramento, CA – A noticeable change in October temperatures is approaching California's capital, where several afternoons in the upper 80s will give way to cooler weather beginning Sunday, Oct. 18. Sacramento is expected to reach approximately 87 degrees Saturday before temperatures ease to 83 Sunday and fall into the lower 70s Monday. The cooling trend will also bring a slight chance of rain early next week, potentially ending a stretch of uninterrupted sunshine. Residents planning outdoor activities should prepare for a considerably different weather pattern by Monday afternoon.
According to the National Weather Service in Sacramento, temperatures are expected to reach approximately 87 degrees Thursday, Oct. 15, followed by 86 Friday and another 87 degree afternoon Saturday. Sunday begins the cooling trend with a high near 83 degrees, while Monday, Oct. 19, brings a more substantial decline to approximately 73 degrees. That represents a 14 degree difference between Saturday's projected high and Monday's expected temperature.
Sunday Begins Sacramento's Cooling Trend Sunday will remain sunny across Sacramento, but temperatures are expected to reach only 83 degrees, approximately four degrees below Saturday's forecast high. Although the change may initially feel modest, it marks the beginning of a larger transition toward cooler conditions across the Sacramento Valley.
Saturday will offer one final afternoon of upper 80s warmth, with sunny skies and temperatures reaching approximately 87 degrees. Clear conditions continue Saturday night, with temperatures falling to around 55 degrees. By Sunday night, mostly clear skies are expected as temperatures decline to approximately 51 degrees.
The most noticeable cooling arrives Monday, when mostly sunny skies accompany a high near 73 degrees. That will be 10 degrees cooler than Sunday's projected afternoon temperature and 14 degrees below Saturday's high.
Despite the cooler conditions, no significant storms or hazardous weather are identified in the supplied forecast for the weekend.
What the Temperature Change Means for Residents The shift toward cooler weather will be noticeable for residents across Sacramento and nearby communities in Sacramento County.

Thursday's forecast calls for light north northwest winds, while Friday brings north winds around 5 mph before becoming calm during the morning. The relatively light winds and clear skies will accompany temperatures in the mid to upper 80s.
