Hilo side: Wave heights for spots exposed to the trade swell are expected to be waist/head high today.
Kona side: Wave heights are expected to be knee/thigh high today with the best breaks a bit bigger on the sets. Spots that aren’t as exposed could be flat.
South: Wave heights are expected to be under waist high high today, some spots could even be flat. Spots catching trade swell could get up to waist/head high.
Small south-southwest pulses linger into the weekend. Nothing significant through at least mid-month. Perhaps something will line up around the 16th.
Trade swell will hold steady. Tropical Storm Howard will generate some east swell that may bring wave heights above advisory levels for eastern shores. Sunday, sets could be occasionally overhead at the best exposures with the winds also weakening.
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.
