What to do when
Good, mixed or best avoided – for each part of the day. A part of the day takes its worst hour, so one thunderstorm at 15:00 marks the whole afternoon.
More than 3 days ahead the forecast is much less certain – use it as a rough guide.

Weather model grid: —. Marine model grid: —.Requested point: 5.940° N, 80.720° E. These are regional models: the weather is the same for all the beaches around Nilwella; what differs is what it means for each activity.
Wave height is the modelled significant wave height offshore, not the height of the waves on the beach. The forecast does not include tides, and it does not say whether it is safe to go in the water – always look at the sea first.
