The difference between the current/recent temperatures and what it usually is like in July feels quite different, even if the actual thermostat numbers only vary minimally. It's because of the cloud cover. It makes the air chillier, so a 77-degree day with a cloud cover is going to feel much cooler than a 77-degree day with sunshine.
We've been below average the last couple of weeks (I'm in the L.A. basin, which is always lumped in with Inland Orange County in the local weather forecasts, and Inland O.C. includes Anaheim) - which is absolutely delightful for me, as I hate the searing, oppressive heat of summer. I couldn't be happier. I only wish it would stay this way through the rest of the month and into August! I have a feeling I won't be so lucky, though!
It's been gloomy in the morning. When the cloud cover burns off, the sun comes out and it feels warm - it will feel even warmer inside DL, however. (That's the "Real Feel" temperature that some weather sites are showing now.) The numbers are suppose to climb next week, and get closer to what it normally would be for July.
