Different fields answer different questions
Wind, waves, sea-surface temperature and sea level describe different aspects of the water. Read each with its time, location and units. A warm sea or sunny sky does not establish calm conditions.
Read waves alongside wind
The sea reflects wind over time and distance. Locally generated waves and arriving swell can occur together, so lighter wind at your departure point does not necessarily mean the wave motion has subsided.
Sea-surface temperature
Regional surface temperature provides seasonal context and a value for the model point. Conditions in shallow water or at diving depth can differ. Use the forecast for the actual date rather than treating a monthly figure as a promise.
Sea level and tide information
A wave-height forecast is not a tide table. Tides, atmospheric pressure and wind can affect sea level. Use a relevant, current source when sea level or clearance matters; do not infer them from the wave-height number.
What Weather.mt currently shows
The marine page displays available regional wave height, direction and sea-surface temperature beside local forecast wind. Missing fields remain unavailable rather than being filled with an assumed value.
