Sacramento, California – Relief from the heat will be short-lived in Northern California as summer temperatures surge back into the 90s by Friday, July 18. Residents in Sacramento and surrounding areas should prepare for extended hot, dry days with little overnight cooling — a typical but potentially taxing summer stretch.

According to the National Weather Service in Sacramento, sunny skies will dominate the region beginning Friday, with highs hitting 92°F by afternoon. A light southwest wind between 3 to 6 mph will offer minimal relief. By Saturday, temperatures rise further to 91°F and hold steady through early next week, with no rain or significant cloud cover expected.

Local travel routes such as Interstate 5 and Highway 99 may see increased vehicle overheating or tire pressure issues — be sure to check fluids and air levels before long drives. Keep water on hand and avoid outdoor activity during peak heat hours between 1 and 5 p.m. Vulnerable groups — seniors, children, and outdoor workers — should take precautions against heat-related illness.

Skies remain clear each night, but overnight lows will hover in the upper 50s to near 60°F, offering limited cooling. Urban areas may feel warmer due to retained daytime heat.

🌤 Five-Day Forecast for Sacramento (July 18–23):

  • Friday: Sunny, high near 92°F. Light southwest wind.
  • Saturday: Sunny, high 91°F. Clear overnight near 57°F.
