Live Swansea forecast: Today and tomorrow’s temperature, rain chance, wind speed and direction, tide times, water-quality checks and activity windows load in the outlook above.
Swansea fronts Swansea Bay, with the River Tawe, marina and docks on the eastern side and the Mumbles headland and pier towards the west. Wind, tide and wave exposure can vary across the curve of the bay and around the river mouth.
Local practical checks
- Choose the exact bay, marina or Mumbles-side access before relying on the town-level forecast.
- Check tide timing and local water movement near the Tawe mouth and harbour areas.
The outlook uses provider-backed weather and tide information for Swansea Bay and the nearby South Wales coast. Use the five-day selector to compare the returned forecast days. A suggested window is planning information, not a safety decision.
