Saturday will remain warm, with highs near 87 under sunny skies. Winds will turn southwest at about 5 mph in the afternoon.
By Sunday, highs will fall to the upper 70s as stronger onshore breezes develop. Low clouds are expected to increase along the coast.
Forecasters said temperatures will continue to cool Monday, with highs in the low 70s. Tuesday and Wednesday will bring slight warming, with highs in the mid to upper 70s.
