A clearer West Sussex forecast
Seyva combines wind, rain, temperature, daylight and tide predictions so you can review the main coastal planning factors without moving between several services.
Match the activity, not just the day
Swimming and paddleboarding are checked separately against starter settings. A proposed session is a prompt for further checks, not a guarantee that conditions are suitable for you.
Check the exact location
Conditions around the coast and the River Arun entrance can differ over short distances. Assess currents, wind, waves, visibility and official warnings before entering the water.
