Heat causing brownout

Not only is the heat wave going to stick around through Labor Day, but it’ll feel hotter than it is — even near the ocean — because of the humidity, forecasters say.

That led Southern California Edison officials to ask the public to cut back on the electricity — meaning, yes, the air conditioner, too — to avoid brownouts.

Newport Beach should only see temperatures in the high 70s to 80s throughout the weekend, but further inland the heat will rise to the upper 80s and 90s, National Weather Service forecaster Mark Moede said.

The high temperatures alone are not cause for worry, but high dew point readings boosts the humidity, causing people to use their air conditioners more than usual, Moede added.

“So you’re looking at that tropical feeling this weekend,” Moede said.

Costa Mesa city workers are doing their part as they cut back on electricity Thursday.

Employees at City Hall were asked to turn off fans, radios, and work in natural light — if possible — during the afternoon.

They’ll probably be asked to do the same Friday, too, city officials said.

Due to near record-high temperatures Edison asked its customers to utilize these energy conservation techniques:

  Set thermostats at 78 degrees or higher and use fans instead.

  Try not to use power tools between 3 p.m. and 6 p.m.

  Block direct sunlight with blinds and curtains while leaving some windows cracked open to let heat out.

  Try to only run full loads in the washer and dryer.

  Close doors and vents to unoccupied rooms.

For businesses, Edison offered these tips:

  Set thermostats to 78 degrees or higher and use fans.

  Use heavy power-consuming machines in morning or evening hours, when possible.

  Shut off lights in unused areas.
