Temperature Outlook June 2023

June to August 2023

JJA night-time (min.) and daytime (max.) temperatures are forecast to be high enough to often be uncomfortable to many, especially because they may end up even higher than usual. Moreover, heat and humidity will ramp up by August as the Caribbean approaches the peak of the annual Heat Season. Recurring heat waves are expected to further compound to sharply increasing heat stress in a summer that may rival the hot year 2020.
