A firm ridge to the south is directing easterly winds, with sea breezes developing during the day. A trough will remain to the east, but will move offshore on Monday morning before moving inland ahead of a weak cold front later in the day. The front will brush past the south coast early Tuesday and will be followed by a strengthening ridge from the Indian Ocean.
