September 29, 2018 Surf Forecast
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 Saturday October 06: Choppy surf along east facing shores will gradually increase this weekend as the trade winds strengthen. Small long-period south- southwest swells are expected to hold into early next week. A larger reinforcing south-southwest swell is expected to fill in Tuesday and peak on Wednesday at heights slightly above the summer average. The current short period north-northwest swell is expected to gradually decrease Sunday into Monday. A slightly larger and longer period northwest swell is expected to arrive Monday night or Tuesday and linger through mid week. A small but longer period east swell generated by east Pacific tropical cyclone Rosa may give a boost to surf along east facing shores during the early to middle part of next week. Surf is expected to remain below advisory levels along all shores through the middle of next week.
Surf heights are forecast heights of the face, or front, of waves. The surf forecast is based on the significant wave height, the average height of the one third largest waves, at the locations of the largest breakers. 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.
