Hilo side: Wave heights are forecast from overhead to double overhead today for the best breaks.

Kona side: Wave heights are expected to be pretty flat today.

Overlapping northwest swells are expected for this week and through the end of the month. A north-northwest should fill in Wednesday. The Big Island will be heavily shadowed from these swells.
