I've been to Disney World during June and it was very hot - how about Disneyland? thanks.
WDW is FAR hotter in the summer than Disneyland. WDW can be downright miserable sweltering heat.
I live in Arizona so know hot well! Disneyland summers can be quite warm or rather cool on any given day but nothing like the incredible heat and humidity found at WDW.
Reminds me of a comedian we saw in Vegas once...saying "But it's a dry heat" and how one will "burst into flames" spontaneously, while walking down the sidewalk.We will be at DL in August so hopefully it isn't that hot. lol But good question OP! I was wondering about that myself.
The other problem is that when I look at weather.com at the highs for anaheim--for some reason when we are actually IN Disneyland it is 10 degrees hotter. I guess it is all of the concrete or lines, but it always is more hot when inside the park.
