nineThe Irish weather has had some bad press. In fact, one joke quips that the usual way to tell the difference between winter and summer in Ireland is to measure the temperature of the rain. While it is true that there are no really major temperature differences between the seasons, and that rain is likely every second day, the Irish weather is manageable. That is if you are prepared for everything it can throw at you, often on the same day.
Temperatures will rarely go below 32 degrees Fahrenheit (zero degrees Celsius) and only occasionally above 68 degrees Fahrenheit (20 degrees Celsius), with June, July, and August being the warmest months, and January and February the coldest. Extremes are not unknown though; the summer of 2006 was one for the ages, with temperatures jumping above 70 degrees Fahrenheit (21 degrees Celsius) nine times. On the other hand, rare freezing spells tend to bring the country to a grinding halt and even a sprinkling of snow will have most drivers panicking.
The best times to travel to Ireland vary based on opinion. At this point, it should be enough to say that March through to June, and the September and October, ranks pretty high, though even a January trip to Ireland can be nice, albeit with short and often bitterly cold days.
