November 2019 brings more Wetter than Average Weather

The autumnal transition continued over the course of November. However, air temperatures remained relatively warm throughout the month, rising to over 20°C on most days. Daytime highs followed typical patterns. Nighttime lows were particularly warm, however. At 20.7˚C, daytime highs exceeded the norm by only a fraction of a degree. At 19.4˚C, nights were just more than a degree warmer than average. Temperatures were fairly consistent over the past four weeks. November air temperatures ranged from a pleasant maximum of 25.9˚C to a cool minimum of 11.6˚C.

The 129.3 mm of rain measured last month exceeded the 93.6 mm expected in November of a typical year. This was the result of spells of bad weather brought about by unstable weather patterns which traversed the central Mediterranean on a consistent basis. The 14 days of rain and 3 days of hail observed last month were greater than the average for this time of year. The 4 days of thunder conformed with the climate average.

Averaging at 10.0 km/h, the wind speed was weaker than the norm. Weaker winds have been a dominant feature of autumn so far. The month’s windiest day was the 25th, when a gust of 61.2 km/h (Force 8) blowing from a Northwest direction.

Atmospheric pressure was lower than the norm, perhaps due to the intense low pressure of a Mediterranean Tropical-Like Cyclone on the 11th and 12th.

Last mnth’s highlight was a Mediterranean Tropical-Like Cyclone on the 11th and 12th. It was responsible for most records this month. It accounted for the only single occasion when the air temperature varied considerably from one day to the next. The margin from the 11th to the 12th was of 5˚C. More than half of November 2019’s rain fell over a span of the two days. The highest 24 hour rainfall was measured at 47.8 mm on the 12th. The severe gale-force winds and heavy rain from the system caused disruption and some light damage.
