This was in large part due to the warm temperatures that carried on into the early autumn. September and October were very mild, with an average of 23.7°C and 20.3°C respectively.
The summer was also extremely hot. During the heatwaves, the temperature high point was 34.9°C, recorded on August 24, 2023. This places 2023 just behind 2022’s record of 35.1°C.
The year’s trends also confirm those observed since the 1970s. Each decade shows a temperature average that is higher than the previous one.
An exceptional drought
In 2023, IMSEE also recorded an average rainfall of 436.4 mm, well below the norm of 794.5mm. It is one of the three driest years recorded in the last two decades (355.6 mm in 2001 and 336.6 mm in 2007).
In fact there were only 46 days of rain in 2023. With a recorded norm of 63 days, this further underlines the exceptional drought experienced in the region.
