Eureka, California – Inland communities across Northern California will sizzle Monday with temperatures nearing 100°F, prompting a moderate HeatRisk warning from the National Weather Service. The hottest locations—such as Hoopa and Willow Creek—could top out near 102°F during afternoon hours.
According to the National Weather Service Eureka office, the heat wave will ease as the week progresses. Inland areas will cool to the upper 80s and low 90s by Wednesday through Friday, while coastal cities like Arcata and Crescent City will see highs in the 60s with persistent morning fog.
Heat-sensitive zones such as Ukiah, Covelo, and Del Loma are expected to remain in the mid to upper 90s Monday before temperatures begin to drop. Overnight lows will stay mild, limiting relief, especially in valleys.
Residents are advised to limit outdoor activity during peak heat, stay hydrated, and check on vulnerable individuals. For coastal areas, fog may impact morning travel visibility, especially near Highway 101 and coastal ridges.
This early June heat event is not uncommon for inland Northern California but serves as a reminder to stay weather-aware. Cooler conditions and increased marine layer coverage are expected to continue into the weekend.
