For Llanharan, the live forecast above shows today’s conditions in the village. As autumn settles in across the Vale of Glamorgan, expect a typical mix of mild temperatures and occasional cloud, with the chance of light rain moving in from the Bristol Channel.

What is the weather like in Llanharan today?

The live forecast above gives the most accurate picture for your exact location. Llanharan sits inland from the coast, so conditions often differ slightly from those in Cardiff or Bridgend. The prevailing south-westerly winds bring relatively mild air, but also carry the risk of patchy drizzle, particularly during the morning and evening. You’ll notice temperatures holding steady in the low teens, with any brighter spells likely to be short-lived.

How does Llanharan’s weather compare to nearby towns?

Because Llanharan is set back from the coast, it can be a degree or two cooler than seaside spots like Porthcawl, and it often misses the heavier showers that affect the higher ground to the north. If you are heading out, checking Bristol Weather can give you a sense of what is moving east, while our UK weather hub keeps you up to date with the broader picture.
