Disneyland Weather Report for the August 5th Weekend from @WDW_Weather

Pretty sharp drop off in temperatures for a high today.  We will end up somewhere right around 80 for a high today with some dense morning fog.  Temperatures will remain in the low 80s all weekend as high pressure that was in effect for most of the week weakens … another reinforcing high pressure will come into the area early next week though so temperatures will ramp back up by Monday and Tuesday back into the mid 80s.

That said there will be plenty of sunshine once the marine layer burns off.
