Publicly accessible observations organised into a continuous sequence.
Ligurian Sea · coastal observation
Right now, the sea is being observed.
Ceonda is reading the latest available signal along the coast.

Purpose
Know whether the sea is moving, even when you are not watching it.
Forecasts describe what might happen. Ceonda observes what is happening along the coast.
It is designed to detect changes that may arrive unexpectedly: a clean residual swell, a sudden increase in movement, or waves beginning to reach the coast while nobody is continuously checking the sea.
How it works
It follows change, not a single observation.
Ceonda uses a machine-learning and computer-vision model trained on years of coastal observations.
At regular intervals, it compares each observation with previous ones and checks whether the same change appears at several points along the coast. This helps distinguish an isolated variation from movement that grows and continues over time.
The model operates during the day and, when the signal is readable, at night as well. If the information is insufficient, it does not force an answer.
- 01
Observes in sequence
Compares every new observation with what happened shortly before.
- 02
Looks for consistency
Checks whether the change continues over time and appears along the coast.
- 03
Returns a signal
Describes the sea as flat, moving slightly, moving, or rough.
Data
Public sources, collected over time and transformed into a signal.
Ceonda draws on publicly accessible coastal sources and marine measurements made available by institutions and monitoring networks.
Observations are collected at regular intervals and organised into a historical series. The model can compare the present with years of sea changes and relate what happens along the coast to the measurements available offshore.
Marine data published by institutions and monitoring networks.
In the future, voluntary reports may help us understand local conditions more clearly.

Why
It began with missed waves.
After returning to Italy following almost a decade in Portuguese-speaking countries, I had lost many of the instincts that once helped me understand whether it was a good day to surf.
Sometimes work kept me busy, and only in the evening would I realise that I had missed good conditions, perhaps after seeing friends' photos on Facebook, Instagram or surf groups.
After too many missed opportunities, I began aggregating the near-real-time data available in the area to follow what was happening along the coast.
The first source of marine data I relied on was discontinued soon afterwards. I did not abandon the idea: I continued observing webcams and collecting information at regular intervals for two years.
That history led to a classifier designed to recognise signals useful to surfers and notify them when the sea changes quickly or interesting conditions begin to form.
Today the model is still being optimised, while some Ceonda features are already running.
Waiting list
Would you like notifications when the sea begins to move?
Ceonda is still experimental. The observation network has grown and we are refining it: join the list and, when we are ready, we will gradually open the service to the public.
