evidence: The vast majority of Northern Ireland has a temperate maritime climate, (Cfb in the Köppen climate classification) rather wetter in the west than the east, although cloud cover is very common across the region. The weather is unpredictable at all times of the year, and although the seasons are distinct, they are considerably less pronounced than in interior Europe or the eastern seaboard of North America. Average daytime maximums in Belfast are 6.5 °C (43.7 °F) in January and 17.5 °C (63.5 °F) in July. The highest maximum temperature recorded was 31.4 °C (88.5 °F), registered in July 2021 at Armagh Observatory's weather station.[133] The lowest minimum temperature recorded was −18.7 °C (−1.7 °F) at Castlederg, County Tyrone on 23 December 2010.[134] [...] As of the 21st century, Northern Ireland is the least forested part of the United Kingdom and Ireland, and one of the least forested countries in Europe.[137]
