The climate in ReunionAverage daytime and nighttime temperatures
All climatic diagrams of this site are taken from the collected data from the official weather station of Reunion at an altitude of 13m above sea level. All data correspond to the average monthly values of the last 20 years.

Long-term development of temperatures from 1992 - 2019In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 1 measuring points in order to have actually comparable data over as long a period as possible.
In the years 1992 to 2019 there were only these 1 weather stations in the whole country, which reported continuous temperature values (Saint Denis Reunion). 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 1998 with 27.8 °C. 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 24.7 °C in the last years before 2019. So in less than 28 years it has increased by about 0.9 °C. This trend only applies to the selected 1 weather stations in Reunion. A considerably more comprehensive evaluation of the global warming has been provided separately.
