Whether you are visiting to see the bright city lights of Dublin or are hoping to get back to nature with an exploration of the lochs, the weather in Ireland is certain to affect your plans. The good news is that regardless of the season, the climate tends to be fairly mild. That means you’re unlikely to have to deal with a lot of extremes. However, because the weather tends to be changeable, you may find that you have to be prepared for a bit of everything.
Nonetheless, Ireland’s climate is rather predictable overall. Spring, which locals consider to be between February and April, usually brings high temperatures of about 50°F. The summer season officially begins in May and runs through August.
This is when weather in Ireland is at its warmest. High temperatures may reach between 65°F and 70°F. Visitors who come in July and August will also experience approximately 18 hours of daylight, which might allow for some extra exploration.
Fall and winter can be lovely times to visit Ireland. Colder temperatures are to be expected, though September and October sometimes rival the summer months for heat. As winter draws near, temperatures may only reach about 45°F to 50°F. However, Ireland rarely gets snow, and temperatures drop below freezing only on rare occasions.
Most people who have been there agree that there is not one perfect time to visit Ireland. Precipitation can happen in any season, and it’s virtually impossible to avoid at least a few days of mists and rains. Still, the countryside looks lovely in these conditions. If you get wet, you can always duck into a pub to pass the time with a pint.
As a shoulder season, many people consider the best time to visit to be spring. Summer is more crowded, but the days are longer, everything is in bloom and it’s possible to enjoy each of the attractions Ireland has to offer. Other visitors swear by autumn or even winter. Essentially, it all comes down to the experience each person is hoping for.
Because Irish weather can be changeable, be sure to bring along light layers, one of which should be waterproof. Along with good hiking boots, layers are absolutely essential for dealing with the vagaries of weather that you are certain to encounter while you’re exploring.
