Eureka, CA – Eureka’s morning commute kicks off under lingering patchy fog Monday, but sunshine quickly takes over by midday, bringing a high near 66°F and calmer winds. Motorists on U.S. 101 and coastal roads should allow extra travel time and use headlights in the early hours, as visibility may be reduced through late morning.
According to the National Weather Service, patchy fog before 11 a.m. Monday gives way to mostly sunny skies across Humboldt County. Winds turn north-northwest by afternoon, reaching up to 8 mph, providing some relief from weekend cloudiness. The cool, marine influence will keep daily highs in the mid-60s for Eureka and nearby communities like Arcata, Fortuna, and McKinleyville through Friday.
Residents should remain alert for dense fog again late Monday night and Tuesday morning, particularly along the coast and river valleys. While no rain is expected this week, fog can impact travel safety on major routes like U.S. 101 and local highways each morning. Charge your phone, check headlights, and drive cautiously if visibility drops.
By Wednesday, conditions stay mostly cloudy with patchy fog in the early hours, but afternoon sunshine returns. Looking ahead, the five-day stretch brings mild, consistent temperatures, ideal for outdoor plans but requiring continued morning vigilance for fog. Another stretch of mostly cloudy weather develops Thursday and Friday, with highs hovering between 62–66°F and overnight lows in the low 50s.
Warnings remain in effect each morning for patchy fog through Friday, especially for commuters on U.S. 101. Stay tuned to the National Weather Service for updates on coastal advisories as the weekend approaches.
