Kinsales climate type according to the Koppen Climate Classification System is a Marine West Coast climate (1). This sub type is classified under the Moist Sub-Tropical Mid-Latitude Climates. These climates experience dry summers and wet winters, with cyclones and tropical storms making the precipitation heavier in the winters (2).
Compared to other parts of the world Kinsale, Ireland, is a fairly cooler climate. From 1991-2021, July had the highest average temperature of 15.6 degrees Celsius (60.1 degrees Fahrenheit) and February had the lowest average temperature of 7 degrees Celsius (44.5 Fahrenheit) (3).
As of 2023, Kinsale, Ireland, saw most of its precipitation during January, October, November, and December. This precipitation came in the form of rainfall with an average of 111 mm during the month of December. With an average of 71mm of precipitation, May was Kinsales driest month (4).
Since Kinsale is near the coast and sees a good amount of precipitation during the winter and fall months, the humidity is higher during those months. As of 2023, September saw more and more intense humidity (5). Throughout 1991-2021 November had the highest humidity with a percent of 82% (5).
The air mass that affects Kinsale Ireland the most is the Tropical Maritime air mass. Tropical Maritime comes from the Atlantic Ocean and brings cloudy skies and precipitation with it. During the winter this air mass can come in and raise air temperatures (7).
Ireland experiences weather events like cyclones, anticyclones, and hurricanes. During the drier months through February and June, Ireland experiences anticyclones that clears the skies and produces little to no precipitation (8). During Late July into the fall Ireland experiences tropical storms. During the 2022-2023 storm season Ireland experienced four main storms. The 2022-2023 storm season ran from early September to late August (9).
In Ireland the wind normally blows from the south and west to northern and northeast lands. In the summer east winds are more prominent bringing drier weather along with it and in the winter times the south winds are more prominent (10).
The global winds that affect Irelands climate are the Westerly Winds (10). These winds are more forceful and stronger during the winter times which is from December to February in the northern Hemisphere (11). Researchers are saying that as climate change increases, the westerly winds will weaken and then weather extremes will become more frequent and harsh (11).
Ireland has a Moist Sub-Tropical and Marine West Coast climate. The average annual temperature of around 49.5 degrees Fahrenheit comes from the influence of the coast and the winds that come from the ocean (12). The precipitation and humidity is related to the marine and west coast influence. The tropical storms and rainfall is also related to the Westerlies winds that is common in the west coast marine climates (13).
