What we’re building
Seyva is a UK coastal planning tool. It combines weather, tide, sea-temperature and available water-quality information, then highlights windows that fit sensible starter settings for each activity.
Why it exists
Getting a useful picture of coastal conditions normally means opening several websites and mentally joining the data together. Seyva is designed to make that first check fast, calm and understandable.
Where it’s going
The public Today page begins with swimming and paddleboarding. More activities, personal preferences, longer forecasts and app features will follow as the service develops.
Seyva is a planning aid, not a safety service or a substitute for local knowledge and official warnings.
