Eureka, Calif. – Headlights glow through a thick blanket of coastal fog across Humboldt County this morning, making visibility the biggest concern before skies slowly brighten later today. Drivers along the North Coast should expect changing conditions through the morning before another round of fog returns tonight.
According to the National Weather Service, widespread dense fog will linger through the morning before gradually lifting. Mostly cloudy skies remain in place through much of the day, with afternoon temperatures climbing to around 63 degrees. Calm winds will become light northwesterly during the afternoon, helping improve visibility for a time.
The biggest impacts will be along U.S. Highway 101, State Route 255, and local coastal roads, where dense fog may reduce visibility significantly during the morning commute. Drivers should slow down, increase following distance, and use low-beam headlights when traveling through fog-prone areas near Humboldt Bay and along the coastline.
Clouds dominate much of the extended outlook. Sunday’s high reaches 64 degrees with another round of dense morning fog before mostly cloudy skies develop during the afternoon. Monday remains cloudy with highs near 64 degrees, while Tuesday introduces a slight chance of light rain and temperatures around 65 degrees.
Meteorologists continue tracking a persistent marine layer that keeps northern California much cooler than inland communities. While much of the West experiences hotter temperatures and monsoonal thunderstorms farther east, the North Coast remains locked into a pattern of cool afternoons, overnight fog, and low clouds.
Outdoor plans are still possible once the fog lifts, but boaters and beach visitors should expect reduced visibility near the shoreline through much of the morning. Travelers should also allow extra time if driving before midday.
Long-range outlooks suggest temperatures may trend slightly above normal later next week, though the marine layer is expected to continue bringing cool mornings to the Eureka area.
