Chetumal, Quintana Roo — Quintana Roo has recorded 22 heat-related illnesses since the start of summer, placing it among the 15 most affected states in Mexico, according to the latest report from the federal Health Department.
The Weekly Report on Health Damage from Extreme Natural Temperatures, covering Epidemiological Week 23 through June 17, 2026, shows that the state ranks 14th nationally. Nationwide, 820 cases linked to extreme temperatures have been reported, with Quintana Roo accounting for 2.7% of the total.
Heatstroke leads the list of conditions in the state, with 12 confirmed cases, followed by six reports of sunburn and four cases of dehydration.
Health officials warn that the Caribbean coast’s climate encourages prolonged sun exposure, increasing risk, especially between 11 a.m. and 4 p.m., when solar intensity is highest. Specialists recommend constant hydration, light clothing, hats, and sunscreen.
At the national level, Tabasco, Oaxaca, and Jalisco have the highest number of cases, while states like Colima and Coahuila report minimal figures. Quintana Roo shows an intermediate trend but with an upward trajectory as the hot season progresses.
Authorities urge both residents and tourists not to ignore warning symptoms such as dizziness, headache, nausea, or disorientation, which could indicate severe heatstroke. The monitoring is part of the Epidemiological Surveillance System operated by the General Directorate of Epidemiology of Sinave.
