Disneyland Weather Report for August 8 from @WDW_Weather

It should remain dry most of the week but the fog will be a concern (as it normally is this time of year anyway) throughout the early morning.  Light showers cannot be ruled out in the overnight/early morning hours.

High temperatures won’t vary all that much – temperatures will be around 82 today and in the low 80s all week.   Monsoonal moisture may move in and lead to some showers and even thunder possibly later in the week.  Lows temperatures will bottom out in the mid to lower 60s all week.
