Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

A moderate short period NNE (020 degree) swell generated by a gale low NE of the state will hold through tonight. Spectral analysis indicates energy with this swell is spread throughout the spectrum, but the vast majority is contained within the shorter period bins. Observations indicate surf is underachieving as longer period energy insufficient to generate High Surf Advisory (HSA) level surf. The HSA has therefore been dropped.

For other shorelines, surf along east facing shores will remain choppy and short-period due to the strong trade winds, with some areas also being exposed to the incoming NNE swell. South shores will continue to see small pulses from the southern hemisphere over the next few days. A storm-force low developing southeast of New Zealand over the next few days could send a moderate south- southwest swell the following week.

WEST

am        pm  

Surf: Minimal (ankle high or less) surf.

Conditions: Semi glassy in the morning with N winds less than 5mph. Bumpy/semi bumpy conditions for the afternoon with the winds shifting WNW 5-10mph.
