Intense heat could occur during the month of October. “A very high-intensity El Niño episode is expected starting in October. (…) This rise in temperatures is one of its impacts,” explained Zo Rakotomavo, Director at the General Directorate of Meteorology, yesterday. It is around October that maximum temperatures will begin to climb, which could mark the start of these extreme heat episodes. “Forecasts anticipate a temperature increase of between 2°C and 4°C. (…) Some days could record temperatures more than 4°C above seasonal norms,” he continued.
It is expected to be hot, but without reaching a heatwave comparable to those observed in Europe. “There will be no heatwave here, because the temperature generally drops as evening approaches and during the night. In Europe, during heatwaves, the temperature barely drops, even at night. It will be hot, but it will not last for several days in a row like in Europe; that is why it will not be a heatwave,” the specialist clarified.
This El Niño episode could also lead to a disruption of the rainy season. “There is a risk of drought, especially in the South. The disruption of the rainy season will vary from one region to another, but we will confirm this when we publish the seasonal forecasts at the beginning of October,” the source added.
Average temperatures are expected to be above normal in a large part of Madagascar, with the exception of Androy and the southern part of the Atsimo Andrefana region, where they are expected to be normal to above normal, according to seasonal forecasts covering the period from August to October. Furthermore, rainfall is expected to be normal to above normal across the entire Great Island during the season from August to October 2026, according to the General Directorate of Meteorology.
