Warmer but Wetter October 2019

October air temperatures ranged from a pleasant maximum of 27.7˚C and a cool minimum of 15.7˚C. They were recorded towards the start and the end of the month respectively. With a mean air temperature of 22.2˚C, October was warmer than average. At 25.0˚C, daytime highs almost conformed with the norm. At 19.4˚C, nights were much warmer than average. Overall, temperatures were consistent throughout October, with no notable heat or cold spells.

The 106.0 mm of rain measured last month exceeded the 83.3 mm expected in October of a typical year. More than half of October 2019’s rain fell in the last week of the month. This was the result of showers and thunderstorms produced by an unstable air mass which remained almost stationary over the central Mediterranean. The 11 days of rain and 8 days of thunder observed last month were greater than the average for this time of year. The highest 24 hour rainfall was measured at 24.6 mm on the 28th, during a set of thunderstorms. The 7th, with a total of 24.1 mm, came in at a close second. A notable pattern observed throughout October were the long periods of dry weather in between equally long periods of wet weather.

Averaging at 7.9 km/h, the wind speed was lower than the norm by half. Weaker winds have been a dominant feature of autumn so far. The month’s windiest day was the 8th, on which a maximum gust of 59.5 km/h blowing from an easterly direction was recorded.

Atmospheric pressure was in line with the norm.
