Swell Summary
A medium size, short period north (360-020 degree) swell generated by the winds behind a stalling front northwest of the islands is arriving this morning. This swell will produce small to moderate size surf along most smaller island north-facing shores through tonight and will gradually decline Tuesday. A mix of small north northwest swells may maintain modest surf along many exposed north and west-facing shorelines Wednesday into Friday. These north swells may wrap around and subtly increase surf along east-facing shores with more northern exposures through Tuesday. Strengthened mid week trades will result in more choppy wind waves along east-facing shores. A very small, long period south (190 degree) swell arriving today will result in an additional foot or two of surf along many south-facing shores through Tuesday before gradually lowering on Wednesday.
