USVI Faces Extended Heatwave Threat as Forecasters Predict Intense Heat Stress Through October

As the Caribbean enters a peak heat season, the USVI is forecast to experience intense heatwaves that could strain power supplies, impact agriculture, and affect productivity in schools and workplaces

As the territory puts Ernesto in the rear view mirror, the beginning of the week brought a different weather concern: a heat advisory was issued for the USVI on Monday, and there will likely be more to come, with the Caribbean Climate Outlook Forum predicting intense heat for the next three to six months.

“Near-record heat causing significant heat stress can be expected until October,” CariCOF says in its latest Heat Outlook (Aug ‘24 to Jan ‘25). The peak of the regional heat season, from now until October, is forecast to be “considerably hotter than usual,” with “intense…night-time and daytime heat,” increasing in humidity as September draws closer.
