Cancún, Quintana Roo — The canícula, a period of intense heat, is expected to last about 10 days in Quintana Roo and the Yucatán Peninsula, with thermal sensations ranging from 40 to 50 degrees Celsius, according to Meteored México.
Meteorologist Juan Antonio Palma explained that the phenomenon will be mild and short-lived. Initially, a longer period was anticipated due to the consolidation of El Niño, but current models indicate the canícula will last just over a week before giving way to the return of constant and more intense rains.
Starting now, there will be a gradual decrease in the distribution and intensity of rainfall in the region. Showers will become more isolated and sporadic over the next ten days.
The combination of high temperatures and residual humidity will worsen conditions across the peninsula:
- Projected thermal sensation: Values will typically range between 45 and 50 degrees Celsius due to the combination of heat and water evaporation.
- Thermal behavior: During the canícula, there is no direct increase in maximum air temperatures, but a substantial rise in humidity levels.
- End of the phenomenon: By late July, an increase in storm systems and the consecutive arrival of tropical waves is expected.
Given the forecast, Palma advised the public to avoid prolonged exposure to the sun outdoors and to maintain constant hydration. Meteorological authorities also urged extra care in food preparation and storage, as humid and extremely hot environments accelerate food spoilage and promote bacterial growth.
