Temperature Outlook September 2023

September October November 2023

SON night-time (min.) and daytime (max.) temperatures are forecast to be uncomfortably high to many until October, especially because they are likely to end up even higher than usual during the peak and end of the annual Heat Season. Moreover, humidity and the frequency of heatwaves in September could even surpass previous months, further increasing heat stress and rivaling record hot months in 2010, 2016 and 2020.
