What’s the outlook for Anglesey today and tomorrow?
The live forecast above gives the most reliable picture for the next few hours. For weather in Anglesey today, expect conditions to be shaped by the prevailing wind off the Irish Sea.

Should I check the 7-day or 14-day forecast?
For planning a trip, the weather in Anglesey 7 days ahead is usually reliable enough for outdoor activities. For a longer view, bbc weather Anglesey 14 days can give a broad trend but expect details to change. For weather in Anglesey 10 days out, treat it as a guide rather than a firm plan—especially if you’re booking coastal walks or ferry crossings.
Is Anglesey generally windier than the mainland?

Does Anglesey get its own weather microclimate?
To a degree. The island often holds onto cloud or sea mist when the mainland is clear, particularly along the north coast near Amlwch and Cemaes Bay. Temperatures also tend to stay a degree or two milder in winter.
When is the best time to visit Anglesey for settled weather?
Late May to mid-June often brings the steadiest conditions, with lighter winds and longer daylight. July and August can be warmer but also carry a higher chance of Atlantic showers moving through.
