Remarkably hot weather on the North Coast this September has many people flocking to their favorite swimming holes and beach spots, but be careful if you choose the coast to cool off, as the first sneaker waves of the season are predicted to start coming in later this afternoon.
Crescent City has been 4.3 degrees above average for the first nine days of September, primarily due a several low pressure systems off the coast, according to the National Weather Service in Eureka.
The upper low pressure systems bring light, southerly winds with warm, dry air as opposed to the cooler coastal element that comes with the northwest winds more common to the North Coast.
Inland communities have had it even hotter. Gasquet had a high of 104 degrees on Sunday and matched or exceeded that Monday.
The National Weather Service issued a heat advisory Monday for southern coastal Curry County, including Brookings.
The warm weather is expected to continue through most of today, but it could become a bit cooler by Wednesday, according to the weather service.
In one of the tell-tale signs of winter’s approach, the first large swell of the season is expected to arrive this afternoon and continue through Wednesday, and officials urged the public to look out for sneaker waves.
“When you get these long swells like this, it results in set behavior where you get larger waves every 20 to 30 minutes,” said Ryan Aylward, meteorologist with the National Weather Service in Eureka.
A large storm system near Alaska is what sent the swell toward Northern California, Aylward said.
If you’re planning a trip to the beach, it’s a safe idea to watch the waves from a distance to see how they act before getting too close to the water.
The jetty in Crescent City Harbor could be especially dangerous, since the water has been relatively calm for months.
