The weather in Ireland has few extremes. Overall, Ireland has a mild but changeable Oceanic climate. The warmest recorded temperature was 33.3 Celsius (91.94 Fahrenheit) at Kilkenny Castle, County Kilkenny on June 26, 1887. The lowest recorded temperature was −19.1 Celsius (−2.38 Fahrenheit) at Markree Castle, County Sligo on January 16, 1881. Ireland weather can be rainy. Statistics show that the greatest recorded annual rainfall was 3,964.9 mm (156.1 inches) in the Ballaghbeena Gap in 1960. 1887 was the driest year on record, with only 356.6 mm (14.0 inches) of rain recorded at Glasnevin. The longest period of drought was in Limerick, where there was no recorded rainfall over 38 days during April and May 1938. Weather in Ireland is typically insular, and as a result of the moderating moist winds which ordinarily prevail from the southwestern Atlantic, it is temperate, avoiding the extremes in temperature of many other areas in the world at similar latitudes. Ireland weather does feature precipitation throughout the year, but it is light overall, particularly in the east. Ireland weather in the west, however, tends to be wetter on average and more prone to Atlantic storms, especially in the late autumn and winter months, which sometimes bring destructive winds and high rainfall totals to these areas. Snow and hail can also result from these storms. Weather in Ireland can be dangerous. The regions of North Galway and East Mayo have the highest incidents of recorded lightning annually (five to ten days per year). In the southern regions, Ireland weather is less likely to include snow. Munster in the south records the least snow with Ulster in the north more prone to snow. Some areas along the south and southwest coasts have not had any snow since February 1991. Weather in Ireland has more extremes in Inland areas, which are warmer in summer and colder in winter. They usually have around 40 days of below-freezing temperatures at inland weather stations, but only ten days at coastal stations. Ireland weather occasionally includes heat waves, most recently in 1995, 2003 and 2006.
