Eureka, California – Temperatures across Northern California are climbing sharply this week, with inland areas like Middletown, Trinity Center, and Covelo expected to reach 90 to 96°F by Wednesday before a cooler air mass moves in.
According to the National Weather Service in Eureka, daytime highs will warm through Sunday and peak midweek under a brief ridge of high pressure. A weak system moving through on Monday will briefly cool temperatures by 5 to 10 degrees before the heat intensifies again Tuesday and Wednesday. Cities like Ukiah (89°F), Laytonville (94°F), and Hoopa (85°F) will see their hottest stretch of the week by midweek.
Residents in coastal zones like Crescent City and Eureka will see more moderate conditions, staying mostly in the 60s. However, inland travelers should take precautions: limit outdoor activity during peak afternoon heat, stay hydrated, and keep pets out of hot vehicles.
Cooler temperatures will return Thursday into Friday as a Pacific trough nudges daytime highs down. No major storm systems are expected, but updates may follow if fire danger increases with the drying trend.
