Sacramento woke up under a low, gray ceiling early Thursday, May 7, with the air feeling more like a damp towel than a spring morning. As of 5:40 a.m. PDT, official observations put the temperature near 55°F, with a sticky relative humidity around 94%. The low clouds are expected to peel back by midday, skies should clear out, and sunshine will help drive afternoon highs to around 83°F, with a light south-southwest breeze. Overnight, temperatures are forecast to slide back into the low 50s.
Late Week Heat Build
The cool, cloudy start will not last. Temperatures are set to climb through the weekend into early next week, with forecasts calling for highs in the low 90s on Saturday and Sunday. By Monday, May 11, the heat really tightens its grip, with highs near 97°F, followed by around 99°F on Tuesday, May 12, and some valley spots potentially cracking the 100°F mark. According to the National Weather Service Sacramento, the region moves from a Minor heat risk on Thursday and Friday to a more widespread Moderate risk Sunday through Tuesday, and daily high temperature records are on the table for the hottest days.
Impacts And Tips
By the weekend, minimum relative humidity is expected to plunge into the 20s and even the teens, which means quicker drying and localized fire-weather concerns in already dry grasses and foothill brush. Residents are urged to shift strenuous outdoor work to the cooler morning or evening hours, stay hydrated, and keep an eye on older neighbors, pets, and anyone living without air conditioning.
