The 2023 Caribbean heat wave was one of the heat waves in the series of the 2023 heat waves. It was an intense weather event characterized by prolonged record-breaking temperatures affecting the Caribbean, South Florida, and the Gulf of Mexico.[1][2]
History
On June 6th, 2023, a high-pressure system from east of Puerto Rico combined with dust from the Sahara, increased humidity, and record-breaking Atlantic temperatures (likely exacerbated by climate change)[3] to form a heat dome, which drove the local heat index to historic highs.[2][4][5]
In early June 2023, a LUMA Energy power plant failed during high demand, causing a power outage that affected over 100,000 people in Puerto Rico. LUMA Energy urged customers to conserve energy, and most of the service was restored by June 7th.[6]
