About us
MareCalmo grew out of a simple question we ask ourselves every summer morning: where can I find the calmest sea today?
Who is behind it
Tullio Conte, doctor in computer engineering and IT consultant. He founded MareCalmo in 2026 and writes its code, its sea model and its articles.
His skill is building models from data and checking them. The sea state you see in the app comes from marine forecasts, from the geometry of each beach measured on the map and from rules written one by one, corrected over time with feedback from people on the beach and with webcams.
He writes the articles himself, starting from analyses of the app's data, and they go out under his name. If you find a mistake, write to him.
The project
Italy's coasts are long and very different from one another: the Adriatic and the Ionian, the Tyrrhenian, the Ligurian Sea, the Sardinian Sea and the Strait of Sicily, the sheltered bays and the exposed stretches, the rocky shores and the sandy beaches. The same windy day that makes one side unusable leaves another completely flat. MareCalmo gathers marine weather forecasts for hundreds of locations and turns them into something immediate: where it's worth going today, based on what you want to do. We cover every Italian coast, from Friuli-Venezia Giulia to Liguria, islands included.
Sign-up optional, nothing to install (although you can add the app to your Home screen like a regular app). Open it, look at the map or the ranking, choose.
How it works, in brief
- For each location we calculate the sea state with six simple levels (from Flat to Very rough), together with wind, water temperature, UV index and chance of rain.
- You can pick an activity - swimming, relaxing, snorkelling, SUP, kayaking, boating, surfing, wind - and the app ranks the locations by how suitable they are for that activity today.
- The forecasts cover today and the following days, so you can plan ahead.

Where the data comes from
MareCalmo does not own a sensor network: it processes high-quality open data.
- Weather and marine forecasts: Open-Meteo, under the Creative Commons CC BY 4.0 licence.
- Maps and locations: OpenStreetMap and its contributors.
The processing, the bathing-suitability indices, the criteria for each activity and the texts are developed specifically for MareCalmo.
