According to Met Éireann, Valentia Observatory took the most rays last month, recording over 166 hours of sunshine — the best it has seen since 1972. However, the month’s sunniest day was September 10, in Belmullet in Mayo which recorded 12.3 hours — its sunniest September day since 1969.
For the rest of the country, things fared pretty well also. With monthly rainfall below average everywhere, most weather stations in the south, southwest and west recorded their driest September in 28 years. Malin Head reported just under a quarter of its average rainfall for September — its driest September since in 81 years. Every region also recorded above average temperatures for this time of year. The month’s highest temperature was 23.9C at Shannon Airport on September 4 — its highest since 2004.
Valentia Observatory and Cork Airport reported 1.7C and 1.6C above their average mean temperature making it the warmest September for Valentia since 1991 and since Cork Airport opened more than half a century ago in 1962.
Most stations across the country reported their warmest September since 2006, while the highest maximum temperatures were mostly recorded on September 4, with parts of the southwest, south and midlands recording their highest September temperatures in seven to 15 years.
Given all this September sunshine, it’s no surprise that wind speeds were the lowest on record (up to 74 years) in places as the month was dominated by extended periods of high pressure.
Met Éireann can’t guarantee a similarly tropical October yet, and the next few days don’t look too promising for shorts and flip flops, with a return to the cold and wet weather expected.
Tonight is forecast to be very wet for much of the east and south, with some flooding in places. If you’re living in the west, expect some rain and hail.
Tomorrow will be cool, fresh and breezy, but heavy showers or rain and hail are expected in most parts of the country, with a possibility of thunder.
While Sunday is expected to begin on a positive note, it looks like it will be more of the same with some very wet and windy weather promised and the possibility of flash flooding.
