November 2023: mild with very wet periods
With an average temperature of 8.2 degrees compared to 7.2 normally, November was a warm month. Furthermore, the month was wet with 245.62 mm in Tielt compared to 67.8 normally. The big absentee in November was the sun, which shone for only 23.1 hours compared to 65 normally.
The minimum and maximum temperatures were initially around the norm for the time of year, but in the second half, it was clearly too warm. The warmest day was 13 November when it reached 15.3 degrees! Overall, this resulted in a month that was slightly too warm.
Storm Ciarán
At the beginning of November, Storm Ciarán brought windy and rainy weather, peaking on 2 November when we recorded gusts of up to 86.9 km/h. The low-pressure systems continued to find their way to us in the following days, leading to a very wet episode with all the known consequences.
Very wet month
Almost every day of the month saw rain, leading to large precipitation totals and waterlogging. Ultimately, 245.62 mm fell in Tielt. Rain fell on a total of 25 days in Tielt, with the most rain recorded on 14 November, when the rain gauge showed 35.05 mm.
Absent sun
The big absentee in November was the sun, which shone for only 23.1 hours compared to 65 normally.
Air quality
Thanks to the windy first days of the month, we had 18 days with good (AQI 0-50) air quality.
As the weather became calmer, air pollution increased, resulting in 7 days with acceptable (AQI 50-100) and 5 days with unhealthy for some (AQI 100-150) conditions.
During periods of calm, stable winter cold, a so-called inversion often occurs: a bubble of cold air that remains trapped beneath warm layers of air. The atmosphere close to the ground becomes heavily polluted with, among other things, fine dust particles.
The polluted air tends to stick to the ground and does not disperse, as there is little wind.
