Surf Forecast - Hawaii

5 Day Surf Forecast

Forecast Updated:
 
Tuesday, December 1, 2020 4:56 PM

Surf Scale: 3 ft = waist high, 4 ft = chest high, 5 ft = head high, 10 ft =double overhead
Swell Direction is direction swell is coming from. 90=East, 180=South, 270=West, 360-0 = North

Forecast does NOT account for enhancing bathymetry (i.e the 'reef effect') common at best breaks. For top spots with swell period 14 +secs, multiply surf size X 1.25-1.5 with peaks X 2 (or consider the stated size 'Hawaiian Scale').

A local gale is forecast tracking from north of Hawaii to British Columbia Thurs-Fri (12/4) with 20-23 ft seas aimed east. And another strong storm is forecast tracking from the dateline to the Gulf Fri-Sun (12/6) with up to 56 ft seas aimed east. A long run of solid surf is possible. And yet maybe another storm to follow.
