Heat advisory issued for SLO County as temperatures soar
San Luis Obispo County was under a heat advisory Thursday afternoon as the mercury spiked along the coastal areas.
The National Weather Service issued the advisory after temperatures in San Luis Obispo had peaked and remained at around 100 degrees for an hour starting at 12:25 p.m., according to a temperature gauge at the county regional airport.
The hot weather hit coastal areas of the county early Thursday, however.
Los Osos, for example, saw temperatures reach around 86 degrees by about 10 a.m., according to John Lindsey, a local meteorologist. By 1:30 p.m., temperatures lowered back to a pleasant 68 degrees, Lindsey said.
The dramatic rise in temperature is thanks to changing wind directions. Cooler ocean breezes from the northwest started blowing into the coastal region in the afternoon, according to Lindsey.
That’s also why inland areas normally seeing the hottest temperatures in the county — such as Paso Robles and San Miguel — didn’t see the mercury surpass 90 degrees until just after noon, according to the Weather Service.
The Weather Service’s heat advisory for coastal San Luis Obispo County was expected to remain in place until 7 p.m. Friday.
The hottest temperatures were predicted to hit on Friday — perhaps soaring into the low 100s in Paso Robles, low 90s in San Luis Obispo and mid-80s for coastal areas such as Morro Bay and Pismo Beach.
Temperatures were forecast to remain hot into Saturday, so the heat advisory could be extended, according to the Weather Service.
“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors,” the advisory said. “Young children and pets should never be left unattended in vehicles under any circumstances.”
