Eureka, California – Drivers on U.S. 101 near Eureka could face patchy fog early Saturday morning, just as Memorial Day travelers hit the road. After a cloudy start, sunshine and calm winds will return, making way for a mild holiday weekend—but cool evenings and visibility issues may still catch some off guard.
According to the National Weather Service, Saturday begins with fog before 5 a.m., followed by clearing skies and a high near 58°F. Patchy fog returns overnight with lows dipping to 46°F. By Memorial Day, Eureka will see mostly sunny skies and highs reaching 61°F, with calm west winds around 6 mph.
Residents should plan around cooler nighttime lows and reduced morning visibility, especially near coastal highways. If driving early, use headlights and reduce speed in fog-prone areas. While no major weather hazards are expected, conditions may affect travel times during peak weekend movement.
Looking ahead, Tuesday and Wednesday bring continued sun and mild temps, topping out around 63°F. Nighttime lows will hover around 50°F, keeping evenings chilly for outdoor plans. This stable pattern offers a welcome break after recent cloudy stretches.
Despite the weekend warmth, no early summer heat is expected. Prepare for layered clothing and stay weather-aware through Thursday, as fog and cloud cycles continue. Another weather alert may follow if conditions shift midweek.
