Portsmouth sea weather & tides

Portsmouth sea conditions for swimming, paddleboarding and kayaking

Live Portsmouth 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.

Portsmouth is a harbour and Solent waterfront rather than a single open beach, with Portsmouth Harbour, ferry routes and the Southsea shoreline close together. Wind, tide streams and vessel activity can differ between the harbour entrances, waterfront and open seafront.

Local practical checks

• Decide whether your planned access is at the harbour, marina or Southsea frontage before using this town-level outlook.
• Treat ferry lanes, harbour entrances and tidal streams as local factors outside a basic weather forecast.

The outlook uses provider-backed weather and tide information for Portsmouth and the nearby Hampshire coast. Use the five-day selector to compare the returned forecast days. A suggested window is planning information, not a safety decision.
