Tradewinds are leaving as a small south swell arrives in the islands on Friday through the weekend, bringing warmer weather and a greater chance of afternoon showers this weekend.

The National Weather Service expects tradewinds to diminish and shift to southeasterly winds in Honolulu in the afternoons on Saturday and Sunday.

Forecasters expect the morning windward and mauka showers over the islands to decrease and afternoon showers in mauka and leeward sections to increase as daytime heating and afternoon sea breezes cause rain clouds to form over mauka slopes.

Tradewinds should gradually start to build Monday and Tuesday with more moderate tradewind weather returning on Wednesday.

The light winds should benefit surfers taking advantage of a small south swell on Friday.

All shores should see some surf with south shores wave heights expected at 2 to 4 feet on friday. North and east shores are also expecting 2 to 4 foot surf and west shores should see 1 to 3 foot waves.
