PUERTO VALLARTA, Mexico – Residents of Puerto Vallarta continue to experience warmer-than-usual weather conditions despite several cold fronts across the country. Víctor Manuel Cornejo López, the advisory meteorologist of the Scientific Committee of Civil Protection of the Bay, has attributed the persistent high temperatures to atmospheric patterns known as “Oestes,” obstructing cooler northern air currents.
Since the commencement of the meteorological fall season, up until November 10, the nation has witnessed nine cold fronts. Nevertheless, these climatic barriers have had a negligible effect on the coastal city of Puerto Vallarta, where temperature readings have consistently exceeded typical averages for this period.
Inhabitants have observed temperatures soaring above 32 degrees Celsius (89 f), with the heat index reaching a sweltering 39 degrees Celsius (102 f), prompting public concern over the anticipated relief from the heat. “The westers act as a shield, preventing the icy winds from the north – carried by cold fronts – from reaching our segment of the Pacific,” explained Cornejo López.
For a significant temperature decline to occur in Puerto Vallarta, a cold front must penetrate either the western or central parts of the country, which would then influence the regional climate. According to Cornejo López, the cold fronts that have made landfall thus far originated from the east and, as a result, did not extend their impact to the city.
Forecasters predict that as long as the current atmospheric conditions persist, the mercury will continue to hover above normal levels. This trend may extend until the conclusion of November or possibly into early December, marking a delayed onset of cooler temperatures for the local community.
