Ireland's location amidst the warm Gulf Stream means that Limerick experiences a mild climate. In winter, temperatures rarely fall below freezing, and in the summer temperatures are conducive to swimming. Warmest months are July and August, with average highs in the seventies and lows in the fifties. In winter, the average high is 52 during the coldest months of December, January and February. Lows stay near freezing during this time.

    Ireland is famous as a lush, green land, which results from the country's steady rainfall. Average monthly rainfall remains above two inches year-round, and achieves an annual high of around 4 inches in December and January. Locals will tell you, however, that the rain falls mostly at night, and even during the winter the sun shines an average of two out of every three days. Nevertheless, make sure you pack a waterproof shell and boots, as you are sure to encounter some rain during your stay.

    Because of Ireland's latitude, days are nine hours long in the winter, and stretch to seventeen hours long during the summer, when the sun shines from 5am to 10pm.
