Advisory-level surf will continue through the night for the exposed north and west facing shores from the current west-northwest swell. A larger swell is forecast late Sunday into Monday, which may bring warning-level surf. When in doubt, don't go out! #HIwx #SurfForecast

A high pressure ridge positioned just north of the Hawaiian islands will be weakened by two passing cold fronts over the next several days. Light southeast winds will allow for daytime sea breezes and nighttime land breezes into the middle of next week. weather.gov/hfo

Whether your a #SurfingSanta or a #SnowBird, your Hawaii Christmas Forecast is going to be a pleasant one. Highs in the lower 80s, Lows in the upper 60s, some light winds, and maybe a raindrop or two. We do have a High Surf Advisory until Saturday morn, be careful in the water!
Pleasant forecast and pic of waves on beach in Hawaii. High Surf Advisory as well.
