Wind and marine forecasts come from Open-Meteo, using DWD ICON and DWD EWAM models. Values describe regional grid cells, not individual cave entrances. The site checks for new data every 15 minutes while visible and withholds rankings when data is missing, over 30 minutes old since retrieval, or over 90 minutes past its current model valid time.

Outlooks compare peak wind, gusts, significant wave height, incoming wave and swell directions, and wave period through the next three daylight hours. We use approximate coastal bearings; exposed route segments, offshore winds, channel crossings, difficult entries and specialist dives add caution. No wave heights are reduced to simulate shelter. Cave and overhead options always need a guide check, even in quiet forecasts.

Editorial poor-outlook thresholds: diving at wind ≥18 kn, gusts ≥25 kn or significant waves ≥1.5 m; kayaking/snorkelling at ≥12 kn, ≥18 kn or ≥0.8 m. Incoming waves at cave coasts trigger poor outlook from 0.8 m for dives or 0.45 m for kayak routes. Offshore-wind and thunderstorm checks can also block a pick. These are conservative comparison rules, not validated operating limits or safety guarantees. “Guide check” can apply well below these values.

Wave height is a significant-wave estimate; individual waves can be larger. Currents, visibility, water quality, boat traffic, local closures, cave surge and your ability are not measured here. Check Malta’s official weather service and your operator before departure. Route length is not used to promise a time window.
