Long-term development of temperatures from 1992 - 2022

In contrast to single record values, long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. An average value would give a distorted result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and distorts the average again. The subsequent long-term development was therefore reduced to only 1 measuring points in order to have comparable data over as long a period as possible.

In the years 1992 to 2022, there were only these 1 weather stations in the whole country, which reported continuous temperature values (Saint Denis). From these weather reports, we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was February 1998 at 27.8 °C. August 1992 was the coldest month with an average temperature of 20.5 °C.

The average annual temperature was about 23.8 °C in the years after 1992 and about 24.5 °C in the last years before 2022. It has therefore increased only slightly by about 0.7 °C over the past 31 years. This trend only applies to the selected 1 weather stations in Reunion. A considerably more comprehensive evaluation of global warming has been provided separately.
