Jannik Sinner is unquestionably a great tennis player. He's the current ATP No. 1 and is likely to stay that way for the foreseeable future, as Carlos Alcaraz is missing time with a wrist injury. But beyond Alcaraz, Sinner might be facing his greatest opponent the rest of his current Wimbledon run.
That is because, historically, the Italian has literally wilted in the heat, and London is going to get hot in the second week of the grass-court major. He was flushed out of the French Open in May in the second round because his body could not take the European heatwave. This is far from the first time Sinner has struggled in such conditions.
There is good and bad to this. For one, Sinner will be fortunate to play under a roof, as neither of the two courts he is scheduled to play on at Wimbledon (Centre Court or Court 1) will be covered. That doesn't necessarily mean they will be air-conditioned, though.
Jannik Sinner could still be facing his nemesis, the heat, at Wimbledon 2026
Wimbledon doesn't have air-conditioned courts. Even the US Open doesn't. While the players might not get rained on, they could still have to deal with some heat and humidity. No guarantee exists that either court will be covered, either. Assuming Sinner, the defending champion, plays on Centre Court the rest of the way after the quarterfinals, that court might not be covered unless it rains.
Or unless the Wimbledon decision-makers have mercy on Sinner and the fans and close the roof. The possibility exists.
On Tuesday, when Sinner is scheduled to play Jan-Lennard Struff in the quarters, the temperatures are expected to reach 30 Celsius (86 degrees Fahrenheit). The match will take place at 1 pm BST (8 am ET), so by the time the match is done, the heat could be at its worst in London. If Sinner versus Struff is close, could the heat be the deciding factor?
If Jannik Sinner gets past Struff, he will play in the semifinals on Friday. The temperatures will dip, but only slightly. The high will be 85 degrees Fahrenheit, and the real feel, according to AccuWeather, will be 88, or 31 degrees Celsius. That could have an effect on the ATP No. 1's form.
The Wimbledon 2026 final will be held on Sunday, July 12, when temperatures will once again be in the upper-mid 80s. Maybe none of that affects Sinner, and he pushes past his opponents for his second straight Wimbledon crown. He might need to beat his other opponents as well as the heat to get there, though.
