Wettest June for 160 Years

Armagh Observatory reports that June was slightly cooler and much wetter and duller than average.

The mean monthly temperature was 12.9 degrees Celsius (55.3 degrees Fahrenheit), that is, about one degree C below the most recent (1981-2010) 30-year average for June. The maximum temperature recorded was 23.2 degrees C on the 27th. The minimum air temperature was 3.4 degrees C on the 10th. There were two nights with grass frost, the nights of 3rd/4th and 9th/10th.

Rainfall amounted to 146.6 mm (5.77 inches), which is almost 151% more than the most recent 30-year average (58.44 mm). This makes last month the second wettest June in Armagh since records began in 1838. June 1852 had a total rainfall of nearly 7 inches.

The number of hours of sunshine was 87.2, that is, about 40% lower than the most recent 30-year average (144.26 hr). This was the dullest June for 25 years, that is, since June 1987, and the second dullest June since the Observatory’s sunshine records began in 1880.

These data refer to observations at Armagh Observatory, which has been recording the weather at Armagh since 1795.
