Eureka sets June 8 rain record as North Coast storm moves in

Eureka picked up 0.55 inches of rain on June 8, setting a new daily record for the date and topping the old mark of 0.39 inches from 2005. The National Weather Service said the rain at the Eureka observing site fell with light rain and fog, and the temperature stayed cool, with a high of 60 degrees and a low of 47.

The June 8 storm also delivered Eureka’s first measurable rain of the month. Through that day, the city had 0.55 inches month to date and 16.15 inches since Jan. 1, which was still 7.49 inches below the normal 23.64 inches for the same stretch. The official record period for Eureka’s climate summary runs from 1886 to 2026, underscoring how unusual it was for June 8 to turn wet enough to set a record.

For Humboldt County, the bigger story was not just one damp day in Eureka but the larger North Coast pattern it fit into. The National Weather Service said rain on Monday would be heaviest north of Cape Mendocino, especially in Humboldt and Del Norte counties, with rainfall rates reaching up to a tenth of an inch an hour along the coast and even higher in the mountains from about 10 a.m. to 5 p.m.

Totals near Crescent City could approach an inch, while the mountains of Del Norte County could see as much as 1.5 inches before the front moved through Monday night. That kind of June rain can complicate road conditions, disrupt outdoor plans and slow the early drying that typically shapes summer tourism, gardening and fire-season expectations along the North Coast.

After the front passes, the pattern is expected to flip quickly. The weather service said dry weather would return June 9, followed by much warmer temperatures later in the week, with interior areas potentially near or above 100 degrees and elevated fire weather conditions developing in Lake County. For Humboldt residents, the contrast is striking: a rare record rain in Eureka, then a fast turn toward heat and drying across the region.
