What’s the weather doing in Harlech today?
Harlech sits on the edge of Snowdonia and the Irish Sea, which means its weather often feels like a blend of mountain and maritime influences. The live forecast above shows the day’s pattern, but be ready for clouds to build from the west and a chance of showers, especially later in the afternoon. Temperatures tend to stay mild, though the breeze can make it feel cooler along the seafront.

The 10 day forecast is worth checking if you’re booking a walk up the castle or a trip to the beach — the wind tends to pick up by the weekend.
Is Harlech weather different from inland Snowdonia?
Yes, often. The sea breeze keeps Harlech slightly cooler in summer and milder in winter than places like Beddgelert or Capel Curig, which sit deeper in the mountains and trap more cloud.
