Forecast for Big Island Leeward

HIGH SURF WARNING FOR WEST FACING SHORES

Swell Summary

Overnight observations at the offshore and nearshore buoys have surged well above predicted levels, which supports larger surf and an increasing likelihood for coastal impacts today as it peaks. See the updated High Surf Warning for more details regarding impacts. A gradual downward trend is then expected through the second half of the weekend. A new pulse expected out of the same direction Sunday night could be enough to keep the surf around advisory levels into Monday before lowering Tuesday into midweek. Surf along east facing shores may rise tonight into Sunday as an easterly swell arrives. This source should peak below the advisory level for east facing shores late Sunday through Monday. Surf along south facing shores exposed to large westerly swells wrapping in will come up today as the west- northwest swell peaks.
