Let me tell you this – if you are not used to the heat do your best to limit physical activity and it may be best to stay indoors because it is going to be HOT today AND tomorrow with temperatures in the interior topping out in the triple digits.
It will be slightly cooler along the coast but the beach will be hot too … I’d expect temperatures easily into the mid and upper 90s. By the time we get through the weekend that marine layer will thicken up and high temperatures will return to right around 80.
Make sure to stay hydrated … and think about this – it will likely be officially hotter in Disneyland than Walt Disney World today!
