Ballycastle’s weather today, as shown in the live forecast above, brings a mix of cloud and bright spells typical of the north Antrim coast. The coastal breeze keeps conditions fresh, with the chance of a light shower passing through during the afternoon.
What is the weather usually like in Ballycastle?
Ballycastle sits on the north-east coast of County Antrim, so its weather is heavily influenced by the Atlantic and the North Channel. Winters are cool and damp, with average highs around 7–8°C, while summers are mild, rarely exceeding 18°C. The town sees frequent cloud and rain, but also enjoys some of Northern Ireland’s sunnier spells when high pressure settles over the Irish Sea.
Does Ballycastle get much wind?
Yes, the town is exposed to south-westerly and westerly winds coming off the Atlantic. Gusts can pick up noticeably along the seafront, especially in autumn and winter. If you’re planning a walk to Fair Head or the Glens, it’s worth checking the live forecast above for wind speeds.
When is the best time to visit Ballycastle for good weather?
Late May to early September offers the mildest conditions, with longer daylight and the lowest chance of heavy rain. Even then, pack a waterproof — the coast can turn showery quickly.
Is Ballycastle weather similar to Belfast’s?
Not exactly. Ballycastle is cooler and windier than inland Belfast, thanks to its coastal position. It also tends to catch more cloud from the sea, though it can be sunnier when the wind comes from the east.
Does it snow often in Ballycastle?
Snow is rare on the coast. When it does fall, it usually melts quickly. The surrounding Antrim hills see more frequent snow, but Ballycastle itself gets only a few dustings each winter.
