A warm and very dry September
Although it cooled down the last week of the month, the rest of the month was very warm with even a couple of days above 30°C (we usually only see one of those every 2 years). This resulted in an overall average temperature almost 1.5 degrees above average.
With only 22.2 mm of precipitation during this was the fourth driest September in the weather records in the region which go back to 1914.
This very dry month put the total for the year of 408.9 mm even more below the average of 683.5 mm.
