About

MadeiraOcean

Read full description

MadeiraOcean app (in experimental phase) was created with the purpose of displaying graphically the results of COAWST (Coupled Ocean Atmospheric Wave Sediment Transport) model, implemented by the Oceanic Observatory of Madeira for Madeira Archipelago. Although the model is regularly validated, it is difficult to guarantee the accuracy of the presented data, as forecasts are predictions and should be considered as such. In this app you can check the forecasted data for air and water temperature, direction and speed of currents, waves and tides, plus precipitation, winds and atmospheric pressure. All these variables are available for more than 30 points around the island, with forecasts for every three hours. Additionally, the satellite data presented in this app come from the Copernicus Marine Service (https://resources.marine.copernicus.eu/).

Know what you'll see before you dive — the first app to forecast both marine life abundance and underwater visibility, at dive sites worldwide. Updated daily. Pick the right site, the right day, and the right season before you ever get wet. WHY DIVESIGHT Weather apps help tell you if you can dive. DiveSight also tells you how good it's likely to be — how much marine life you're likely to encounter and how far you'll see, days in advance, anywhere in the world. It's the difference between hoping and making decisions based on the best ocean intelligence available. THE FORECASTS - Marine Life Index (0–100) of abundance for every site, updated daily — see which days will be better than usual, up to a week ahead. - Underwater visibility — including the tens of thousands of sites no crowdsourced app has reports for. DiveSight predicts visibility worldwide from satellite data and fisheries oceanography. Plan your dive with confidence. – 10 years of monthly climatology per site: water temperature, visibility, currents, weather, wind, and more — so you can pick the actual best month to go, year over year. – Depth-resolved conditions: temperatures at the surface, 10m/30ft, and 30m/90ft, plus currents, waves, tides, sun, and moon.
