Coastal Orange County remains relatively cool as heat spreads through the region

Summer has officially arrived in Orange County.

With the start of the junior lifeguard season in Newport Beach on Tuesday, meteorologists noted that temperatures have cooled after a particularly hot Monday. Temperatures in the OC hovered anywhere between the 70s in coastal towns like Huntington Beach and the 90s further inland in towns like Fullerton.

That mirrored other parts of the state, where the National Weather Service noted temperatures in parts of Los Angeles County and the San Gabriel Valley were reaching the 90s and above.

On Tuesday, temperatures were closer to the mid-70s in coastal Orange County and the 80s inland.

“There’s a big spread from the coastline to the interior part of Orange County,” said NWS meteorologist Mark Moede. “You have your 70s, 80s and 90s in one county.”

Temperatures are expected to climb again about 3 to 5 degrees on Wednesday, where they will likely remain through the weekend, according to NWS meteorologist Stefanie Sullivan.

Sullivan said temperatures this week were slightly above average for the county, but not unusual for this time of year.

No daily record was set on Monday.

Moede noted that monsoon humidity would move into southern California from Tuesday evening through Wednesday.

“This is the time of year when we will have wind… [that] start sucking in moisture that comes from the Gulf of Mexico and the Gulf of California all the way to our south,” Moede said. “It will tap into that moisture and start moving towards southern California. This is how Arizona and New Mexico get their seasonal rainfall during the monsoon season.

“This event does not appear to have enough moisture and will not last long enough to cause a high threat of flash flooding.”

Sullivan noted the possibility of showers or thunderstorms in Orange County once the humidity sets in overnight, but said as of Tuesday afternoon, it didn’t look like much. part of the rain, if any, would remain for a long time.

The storms, Sullivan said, would move too quickly to produce much rain in a single town in the county.

“The best chance for [rain] are going to be east of Orange County in the mountains and desert, but there could be a shower or thunderstorm moving west of the mountains, but the odds are lower,” Moede said.

Record temperatures were last broken in Newport Beach in 2017 when the city recorded 102 degrees, breaking a 52-year-old record of 85 degrees set in 1965.

The onset of summer and its warmer days are being welcomed by at least one Balboa Island owner, Courtney Alovis, owner of Sugar n’ Spice, who said the business, where the Alovis and their staff sell frozen bananas and Balboa bars, has been busier than it has been since 2019.
