North: Wave heights are expected to be double to triple overhead today. The best breaks could get even larger early on. Surf will be on a downward trend through the day.
West: Wave heights waist/chest high are expected today. The best exposures could get up to shoulder high on the sets from time to time. Spots shadowed by other islands will be smaller. Some north-northwest will fill in for breaks open to the swell bringing knee/waist high waves.
South: The south-southwest is expected to bring waist/chest/shoudler high waves today. The best breaks could be a bit bigger from time to time.
Another more ‘westerly’ swell (295° to 315°) is expected on the heels of the current swell energy. This swell is forecast to quickly build Thursday and mix in with our current swell for head high to well overhead waves. This swell should peak Friday before slowly fading.
Our current south-southwest peaked Tuesday and has begun to gradually ease Wednesday. A new south-southwest fills in Thursday/Friday to keep wave heights around waist/chest high.
Next week another pulse of south-southwest is expected. Will keep an eye on it.
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.
