Extreme heat in the USA alerts World Cup organizers

The United States National Weather Service has issued extreme heat warnings across parts of the country and Canada, coinciding with the round of 16 matches of the World Cup. The situation has prompted special attention from athletes, coaching staffs, and FIFA officials.

Forecasts indicate heat indices will rise above 40°C in several host cities. The match between Paraguay and France is of particular concern, with projections suggesting the heat index could surpass 42°C. The combination of high temperatures and elevated humidity significantly increases physical strain on players over the course of 90 minutes.

This heatwave, moving from the Midwest toward the east, is expected to peak around the July 4th holiday. Beyond daytime highs, authorities are concerned about the lack of nighttime cooling, as temperatures are expected to remain above 20°C, hindering the body's recovery process after physical exertion.

Host cities have adopted specialized protocols to manage the conditions. In New York, authorities have expanded cooling centers and installed hydration stations, while Chicago has opened climate-controlled spaces to support vulnerable populations. Similar conditions are being managed in Canadian host cities like Toronto, where heat indices are also reaching critical levels.
