This weekend, daytime highs in Eureka will be in the mid-to-upper 60s — cooler even than San Francisco, so famed for its chilly summers.This summer is sticky and muggy for many of usFor huge swaths of California, the National Weather Service has issued extreme heat warnings through this weekend, and much of the state is perspiring through an unusually humid summer thanks to warmer ocean temperatures, tropical storms offshore and surges of monsoonal moisture.Wildfires are raging across much of the American West — including Oregon and Washington — and in Canada.And while scientists say a so-called “super” El Niño brewing in the Pacific could, in the coming months, bring much-needed precipitation, the Western U.S. still is “suffering the consequences of a hot winter and meager snowpack, in part thanks to El Niño’s polar-opposite sister, La Niña, which brought cool ocean water to South America’s Pacific coast and drier conditions to the Southern U.S.,” my colleague Noah Haggerty reported last week.But in Eureka, things are pretty chillIn Eureka, a city of some 25,000 people in Humboldt County, there’s an oft-repeated saying about residents: “They don’t tan. They rust.”That’s because the air is usually so misty and salty.The cooler summer weather is, in large part, because of the local geography. When it is hot inland, warm, thinner air there rises in the atmosphere, and cold marine air is sucked in, like a vacuum, to fill the void. The warmer air aloft acts like a lid, trapping the heavier, cooler air, which can’t easily flow over mountains. Eureka is one of the most reliably cool places in California during the summertime. (Myung J. Chun/Los Angeles Times) The highest temperature recorded in Eureka is 87 degrees, according to the weather service. The mercury hit that number three times: in October 1993, September 2017 and September 2020.According to Climate Central, a nonprofit research group, the average summer temperature in Eureka rose 1.6 degrees between 1970 and 2025, to about 58.5 degrees.Though the overwhelming majority of U.S. cities have had shorter, hotter winters over the last 50 years because of climate change, Eureka is one of the very few to buck the trend, with its winters becoming slightly colder, per Climate Central. Since 1970, the average winter temperature in Eureka has dropped 1.3 degrees.White, who grew up near Atlanta, said he can’t complain about the mild weather in Eureka, where the National Weather Service forecast office is set on little Woodley Island.“A lot of times in the summer, we have the AC turned off at our office. We can just open a window and that helps,” he said. But with temperatures near 70 and the fog not as thick, he said, “it’s kind of funny — we turned our AC on this week. It gets warm in here just from the sun heating the building.”Today’s top stories (Allen J.
