What does the forecast for Llanelli show today?
The live forecast above reflects Llanelli’s position on the Carmarthenshire coast, where sea breezes and incoming weather fronts often bring quicker changes than inland spots.

If you’re planning a trip to the beach or Pembrey Country Park, note that coastal mist and wind gusts can arrive without much warning, so keep an eye on the hourly breakdown.
How far ahead can I rely on the forecast?
