Big Island Surf Forecast
Hilo side: Wave heights are forecast to be head high to overhead or more today.
Kona side: Wave heights are expected to be knee/waist high today with the best breaks getting up to tummy/chest high.
South: Wave heights are expected to be knee/waist high today with the best breaks getting up to tummy/chest high.
Small overlapping south to south-southwest swells are expected to continue through the middle of the week with the energy fading Thursday/Friday. We expect something fun to build Friday for the weekend. Long range models are showing we may get a good swell toward the end of the month. Will keep an eye on it.
East trade swell continues at advisory levels through Wednesday before easing. Modest northwest swell is forecast to build on the 18th, hold through Thursday and ease Friday. Later in the weekend, a larger northwest swell is expected to fill in through the day Sunday, peaking Sunday night into Monday, then easing early next week. This swell will gradually shift out of a more northerly direction and hold into midweek as it trends down.
Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
