About

Drawing on my own experience at the helm of a small boat, I wanted one map with the information a skipper needs to plan a day on the water. That was the beginning of Sea.Net.Gr.

Choose a destination to see the wind, waves and approach conditions at the time you have in mind. Once on board, you can find nearby ports and marinas.

The site was designed and built by the teams at Iridium artlab and Iridium Marine, with care at every stage and commercial licences for the forecast services.

Choose a place and time

Tap a point on the map to open its local forecast. At the top you will find wind in Beaufort, temperature, wave height and an estimate of approach conditions for small boats around six metres long.

If you plan to arrive at 12:00, tap the corresponding time on the bar “Hourly approach conditions” to see the forecast for that hour. On a computer just hover over the bar. You can compare different arrival times. All times are local to Greece, in 24-hour format.

If you are still choosing a destination, the home page lists the three most favourable and three least favourable approaches for the coming hour.

When you are on board

With “Near me”, if you allow location access, you can see the nearest forecast and nearby ports and marinas. Each entry shows the straight-line distance, in nautical miles, and the direction from your position. With “Show on map” you can see where the port or marina lies relative to your boat.

Straight-line distance gives you an initial estimate. To plan your actual route, consult a nautical chart of the area. Before departure consult official forecasts, port instructions and the skipper’s own judgement.

From one skipper to another

When planning a trip with friends, “Share forecast” lets everyone see the same destination forecast and choose a time together. To tell someone where you are, send your position with “Share location”.

If you found Sea.Net.Gr useful, I would love you to share it with someone who enjoys the sea too.

Fair winds!
