Disneyland Weather Report for June 30 from @WDW_Weather
The big story over the next couple of days is going to be the warming temperatures. As high pressure builds in - I tell ya the heat is going to be on for sure! In fact by Sunday we are going to be flirting with 90 degrees for a high temperature.
Thanks to this high pressure building in - the marine layer will be suppressed to the coastal areas ... and dry conditions will prevail. All in all it's looking like a great weekend to get outside and enjoy some family entertainment.
Temperatures slide a bit after Sunday, but will still be in the mid 80s for your 4th of July.
