Our weather team will bring you any urgent weather alerts or updates as they occur. Check our breaking news section for the latest.
Outlook through Wednesday July 18: Breezy trade winds will keep rough choppy surf along east facing shores through the week. An increase in trade wind swell is expected over the weekend as trades upstream strengthen. Surf along south facing shores will get a small boost today, followed by a Tasman Sea SW swell over the weekend. The SW swell is expected to slowly fill in on Saturday and peak Sunday or Monday near the summer average. No other significant swells are expected.

Some waves may be more than twice as high as the significant wave height. Expect to encounter rip currents in or near any surf zone.
