LEEWARD MAUI MARINE CONDITIONS
Maui Marine Weather: read the forecast like a mariner.
Wind, seas, period and swell direction shape every day aboard a small power catamaran. Plan your Kīhei departure by the marine zone forecast and the conditions you actually observe—not just an app’s sunshine icon.
WIND · KT
Wind direction and gusts
Review sustained wind and gusts in knots; trades can accelerate near points, channels and open coasts, particularly in the afternoon.
SEAS · FT
Combined seas and wind waves
Wave height is only part of the story: assess short-period chop, swell direction, wave period, and how the boat will meet them.
VIS · NM
Visibility and advisories
Monitor rain squalls, reduced visibility, small-craft advisories and notices that can make a planned route inappropriate.

BEFORE DEPARTURE
Read the trend
Compare forecast morning and afternoon wind, sea-state changes and swell. Save a return-time margin.
UNDERWAY
Monitor conditions
Look for building whitecaps, lightning risk, rain lines, lee shores, cross-seas and fatigue. Adjust course early.
IF CONDITIONS WORSEN
Return safely
Reassess rather than push on to a planned stop. Do not use a website forecast as a substitute for seamanship.
