Eureka, CA – Residents will experience a dramatic temperature swing this week, with an unseasonably warm Tuesday giving way to a much cooler pattern. A surge of summer-like heat will push the high temperature to near 83 degrees, a sharp contrast to the typical coastal climate.
According to the National Weather Service, patchy fog is expected to affect areas around Eureka before 11 a.m. on Tuesday. The fog will then give way to partly sunny skies, allowing temperatures to climb rapidly. Light and variable winds will become northwest 5 to 7 mph in the afternoon, offering little relief from the unusual warmth. Drivers along U.S. Route 101 should remain cautious of reduced visibility during the morning hours before the fog lifts.
The abrupt heat is short-lived. By Tuesday night, clouds will increase, and temperatures will drop to a low of around 49 degrees. This cooling trend continues into Wednesday, which will see a high of only 58 degrees with mostly cloudy skies. The rest of the week will settle into a stable but cool pattern, with daytime highs hovering in the upper 50s.
This pattern of partly sunny days and mostly cloudy nights is expected to continue through the weekend. No significant weather advisories are anticipated after Tuesday, but residents should prepare for the quick shift from summer heat back to cool, coastal conditions.
