For the latest Porthcawl weather, the live forecast above gives you conditions right now. This seaside town on the south Wales coast enjoys a mild maritime climate, though sea breezes can make it feel cooler, especially when the tide turns.
What should I expect from Porthcawl’s weather today?
Based on the live forecast above, you’ll see how cloud, wind and any rain are shaping up. Porthcawl sits on a promontory in the Bristol Channel, so it often catches sea breezes that keep temperatures a few degrees lower than inland spots. If you’re heading to the beach or walking along the harbour, check the wind direction: south-westerlies bring moisture and cloud, while north-easterlies tend to bring clearer, cooler air.
How does the wind affect Porthcawl compared to nearby towns?
Wind is the main talking point for Porthcawl. The live forecast above will show you gusts, which can be strong around the coast. This exposure makes it popular for watersports but also means you’ll want a windproof jacket. On stiller days, the weather can feel much warmer than the numbers suggest. For comparison, inland towns like Bristol Weather often see less wind, so our forecasts for Porthcawl keep a close eye on that extra coastal element.
Is Porthcawl always windy?
Not always, but it is windier than many inland spots. The Bristol Channel funnels south-westerly winds, so gusts over 30mph are common in autumn and winter. On a calm day you can enjoy much milder conditions.
What’s the best time to visit Porthcawl for good weather?
Late spring (May–June) often sees the most settled weather, with lighter winds and less rain. July and August are warmest but can bring sea mists. Autumn can be stormy but dramatic for watching the sea.
Does Porthcawl get fog?
Yes, especially in spring when cold sea air meets warmer land. “Haar” can roll in off the Channel, reducing visibility to a few hundred metres. It usually clears by midday if the sun breaks through.
