The ATP Tour and its players are currently preparing for another season, which is rapidly approaching.
Many players have already signalled their intentions for the start of the 2026 ATP season, with Novak Djokovic signing up to the Adelaide International.
Meanwhile, Jannik Sinner will start his season at the Australian Open, the first Grand Slam tournament of 2026.
The ATP Tour will be all change in one particular area by then, having finally caught up with the WTA Tour’s heat rule policy.

Every player should love the new ATP Tour heat rule
A new ATP heat rule will come into play from 2026, which is aimed at helping players deal with extreme conditions while playing.
Clear thresholds for cooling measures and suspension of play in best-of-three singles matches have been introduced, which is welcome news for everyone on the ATP Tour.
Players have often found it difficult to compete when the conditions prove too much, never mind perform to the best of their ability.
Who is your favorite ATP player right now?
But that should no longer be an issue with the introduction of this policy, which should also improve the spectacle for fans.
New factors such as the 10-minute cooling break should prevent fatigue, which has impacted so many ATP players in recent times.
The number of retirements during matches may also decline thanks to the measure, which is again a boost for all parties.

The ATP heat rule is a short-term and long-term boost
The ATP heat rule has come long after the WTA’s, but the good news for players is that it has arrived before the Australian events.
The action starts with the United Cup at the beginning of January, which takes place across Perth and Sydney.
There are also ATP 250 tournaments in Brisbane and Adelaide before the Australian Open arrives in Melbourne.
If you could change one rule in tennis what would it be and why?
Of course, it isn’t just in Australia that players feel the heat, while issues such as humidity also create a big problem for those on court.
It is once again a packed schedule on the ATP Tour in 2026, but along with providing short-term relief, the heat policy should also be a positive in the long term.
