JULY COOLER, DRIER, AND DULLER THAN AVERAGE – Astronotes

Armagh Observatory stories that July 2024 was cooler, drier, and duller than common, the primary time this has occurred at Armagh since 2011.

The imply temperature this month was 15.1 levels Celsius (59.2 Fahrenheit).  Though that is roughly 0.26 C hotter than the 225-year long-term (1796-2020) common July temperature at Armagh (14.87 C), it’s 0.59 C cooler than the newest (1991-2020) 30-year July common (15.72 C).  This was the best July at Armagh for 4 years, that’s, since 14.6 C was recorded in July 2020.

The warmest day, or highest each day most, was 24.3 C on the nineteenth, adopted by 22.6 C on the thirty first and 22.4 C on the twenty eighth.  The warmest day this month was barely cooler than the warmest final month (24.8 C, on June twenty fourth), so that continues to be the warmest day of the yr up to now at Armagh.

The best day, or lowest each day most, was 14.2 C on the tenth, adopted by 14.8 C on the ninth and 16.5 C on the eleventh.  The very best minimal temperature, normally the warmest evening, was 14.6 C on the twenty fifth, adopted by 14.3 C on the night of the twenty third (and due to this fact attributed to the twenty fourth) and 14.1 C on the 18th.  The bottom minimal temperature, normally the best evening, was 7.0 C on the eighth, adopted by 8.1 C on the twelfth and eight.4 C on the sixth.

There have been no air or floor frosts this month.  The best floor frosts have been 0.7 C on the eighth, adopted by 1.1 C on the twelfth and a couple of.7 C on the ninth.

 There was no thunder or lightning this month at Armagh, nor any rainbows.  On the sixteenth the observer noticed a rook chasing off a buzzard, a a lot bigger hen.  It is a surprisingly widespread prevalence when the smaller hen (rook or gull) acts instinctively to guard their younger.  On the twenty ninth, within the insect world, a wasp was seen attacking and rapidly despatching a big fly.

Complete precipitation was 49.15 mm (1.94 inches) together with seven hint values, that’s, 48.8 mm if hint values are ignored.  That is simply two-thirds of the 183-year long-term (1838-2020) common July precipitation at Armagh (73.4 mm) and roughly 71% of the marginally decrease most up-to-date (1991-2020) 30-year July common (69.0 mm), making this July drier than common at Armagh.

Opposite to broadly reported predictions earlier within the yr of a washout summer time for the UK, the three months Might, June, and July have every been drier than common at Armagh and this yr has seen no days with extra than 25.0 mm (about an inch) of precipitation at Armagh.  Rain has been as frequent as ever however typically in comparatively small quantities.  This has maybe given the impression of a moist month regardless of the instrumental file. At Armagh, the wettest July day was 14.9 mm on the ninth, adopted by 6.9 mm on the twenty sixth and 4.4 mm on the twenty second.

With simply 116.5 hours of robust sunshine, July 2024 was duller than common, supplying solely 85.7% of the 140-year long-term (1881-2020) July common (135.9 hours) at Armagh and 86.4% of the newest (1991-2020) 30-year common (134.8 hours).  This was the fifth month in a row at Armagh duller than common, which partly explains the perceived poor summer time and lack of scorching summer time days.  The sunniest day was the eighth, with simply 9.8 hours of robust sunshine, adopted by the 4th with 9.0 hours and the thirtieth with 8.9 hours.
