Jannik Sinner is struggling with the London heatwave, training in temperatures as high as 93°F ahead of Wimbledon.

What happened?

The Italian tennis player was spotted using ice packs during practice to get some relief from the heat.
Sinner will hope to overcome the heat as he begins his title defense at the All England Club next week.
He succumbed to the scorching sun in Paris last month, losing to Juan Manuel Cerúndolo in five sets.

Why it matters for Jannik Sinner

The World No. 1 will need to adjust to the conditions better during Wimbledon, with the European heatwave expected to ease next week.
Temperatures are forecast to range between 75 and 85°F for the first week of the Grand Slam.
Sinner hasn’t played on the ATP Tour since his shock early exit in Paris, but will make his return to action in an exhibition tournament.

What comes next?

He will take part in the Giorgio Armani Tennis Classic in London, facing Cameron Norrie on Wednesday.
The event will also feature Ben Shelton, Flavio Cobolli, Casper Ruud, and several other top ATP Tour players.
Sinner told Vogue that he hasn’t played any matches on grass, so the first few matches will be difficult.
But if he can get through them, he knows the confidence on grass can come back.
Sinner will be the overwhelming favorite to win a fifth Grand Slam at Wimbledon, with Carlos Alcaraz still sidelined due to a wrist injury.
He has lost just one match since February, going on an incredible run of 30 matches in a row before his loss to Cerúndolo.
Among the other big names expected to be in contention are Novak Djokovic, French Open champion Alexander Zverev, and last year’s semifinalist Taylor Fritz.
Sinner's ability to cope with the heat will be crucial in his bid to win another Grand Slam title.
The Italian player will need to use all his experience and skill to overcome the challenging conditions.
And with the heatwave expected to ease next week, Sinner will be hoping to make a strong start to the tournament.
But for now, he is focused on getting used to the grass courts and finding his rhythm.
So far, it's been a tough challenge, but Sinner is determined to succeed.
The 2026 Wimbledon Championships are just around the corner, and Sinner is ready to defend his title.
