When to go Ireland ?
Ireland is best visited between May and September, but the country also lends itself wonderfully to off-season stays. And with a multitude of direct flights from all French regions, it is very easy to go there, even if only for a weekend. Beware: some hotels in the provinces are closed during the low season, so it is essential to book (long) in advance if you want to come and celebrate St. Patrick's Day (March 17).
The Irish climate is an oceanic, mild and temperate climate. In autumn, temperatures are around 10°C. Winters are, without exception, quite mild, and temperatures range from 3 to 8°C. Spring can still be quite cool. Summers are generally warm, and temperatures rarely exceed 20°C. In Ireland, the weather is fine when it is not raining! Showers are unpredictable (and frequent) in all seasons... And it can be sunny 5 minutes later.
