According to the live forecast above, Harlech is currently experiencing conditions typical for a coastal town in Gwynedd. The key takeaway is that the weather changes quickly here, so check the live forecast before heading out.
What is the weather like in Harlech today?
Harlech sits on the west coast of Snowdonia, so its weather is heavily influenced by the Irish Sea and the nearby mountains. The live forecast above shows the current temperature, wind speed, and chance of rain. Expect cloud cover to build from the west, with showers possible at any time. Wind speeds often pick up in the afternoon, especially near the castle and beach.
How does the coastal location affect Harlech weather?
The sea keeps temperatures milder in winter and cooler in summer compared to inland Wales. However, the prevailing south-westerly winds bring frequent rain bands. The mountains to the east can trap cloud, making Harlech cloudier than towns further inland.
