Temperatures could exceed 30C and humidity will hit nearly 80% when Scotland face Brazil in Miami next Wednesday – conditions that will feel far hotter than the thermostat suggests. It is the final group game of a World Cup that has already forced hydration breaks, ice jackets and cooling towels onto the pitch, and for Steve Clarke’s side it presents the sternest test of their acclimation yet.
Scotland’s opening win over Haiti in Boston was played at a relatively mild 25C, but the heat has been building. When they return to the same venue on Friday to face Morocco, the kick-off being three hours earlier means warmer conditions are likely – the forecast is 27C. Then comes Miami, where the combination of 30C-plus temperatures and oppressive humidity will push players to their limits.
“Scotland's final World Cup group game against Brazil could see temperatures over 30C with 80% humidity.”
Clarke’s squad has been preparing for this since early June, flying out to Fort Lauderdale for an extended warm-weather camp. Sun cream, tan-lines and ice buckets were part of the routine as they trained under the Florida sun before their final warm-up win over Bolivia in New York. Their current training base is in Charlotte, North Carolina – roughly midway between Boston and Miami – where temperatures have already hit 30C.
Before they even left Scotland, some players visited the University of the West of Scotland’s extreme environments chamber, which was able to replicate the humidity and heat of Miami. “It’s 10 or 12 days that Scotland have been there so the acclimation and adaptation to the conditions has probably taken place quite nicely,” said Vish Unnithan, a professor of sports science and exercise physiology at the university. “Maintaining hydration and fluid levels, but also nutritional recovery is going to be key. We know when you’re exercising at the intensity these guys are exercising in the heat, the rate at which you use stored carbohydrates is much faster. So the nutritionists with the Scotland team will be key to making sure the carbohydrate intake is where it should be.” Unnithan added that players sweat at different rates, requiring individualised hydration and recovery programmes.
Morocco and Brazil possess players far more accustomed to living and playing in heat, giving them an edge. But after a long club season, residual fatigue is a factor – and that may play to Scotland’s advantage, with their own conditioning and early arrival helping offset the disadvantage.
Speculation over Clarke’s starting XI for the Morocco match has already begun. A predicted lineup in the Scotsman does not include Ben Gannon-Doak, instead featuring a Celtic man in a system change as Scotland face a dangerous Moroccan side.
The heat is not going away. With one of the toughest games in the group still to come, Scotland’s ability to manage the conditions could decide their fate.
