Heat Wave to Hit Rancho Bernardo This Weekend; How to Keep Cool

Put away your skinny jeans and your beer—a heat wave is coming.

Temperatures in Rancho Bernardo are expected to hit the upper-80s to low-90s by the weekend, part of a regional warmup that could make life miserable if you're not ready. The National Weather Service predicts the hottest weather is likely coming Friday through Monday, with inland valleys looking at highs up to 105º.

Ouch.

So while you're stocking up on popsicles and finding places to plug in all of your fans, think about making plans to drop in at one of the local county Cool Zones for free air conditioning and a chance to hang out with other people in the community.
