About Seyva

Less searching. More time on the water.

Weather apps tell you the weather. Tide sites tell you the tides. Seyva brings the signals together and turns them into a practical daily outlook for people who swim and paddle.

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.
