Schedule your test-taking for cool, damp, gloomy days. When it's sunny and spectacular avoid operating heavy machinery or doing anything that requires thinking.
That's the take-away from research out of Australia and Harvard (details on the blog below) showing that when it's sunny we tend to be happier, which sends a signal to our brains that all is well and there's less need to think deeply and carefully. It's an oversimplification - but beautiful weather makes us dumber. OK.
This may explain L.A.
Our collective IQ drops a few points into next week as an authentic hot front approaches from the Plains, kicking up a few stray weekend storms and potentially beastly dew points in the 70s. A tropical, sauna-like airmass oozes into town this weekend, inspiring many of us to go jump in a lake.
NOAA guidance hints at 90F by Sunday with a dreadfully-drippy dew point in the 70-75F range next week with a heat index topping 100F at times. Throw in some smoke from Canadian fires and you have one giant barbecue and we're all invited!
The core of this midsummer heat wave passes just to our south but I suspect the next 2-3 weeks will be the hottest of the entire year.
Possibly the dumbest too.
