The 2025 Isle of Man TT could be hit by disruption due to bad weather, the Met Office predict.

The TT is set to begin on Monday May 26 and runs until Saturday June 7.

Only two vacant days are currently built into the 2025 Isle of Man TT schedule.

Forecaster Colin Gartshore of the Met Office, based at Ronaldsway, has warned of problems ahead.

“It will be mixed next week, and I would be extremely surprised if we get away with no disruption to the five practice days,” he told the Isle of Man Today.

“It is almost guaranteed there will be issues next week and the weather could be bad on Monday.

“It is all change next week and it is likely this unsettled weather will go into race week as well.”

Forecaster Neil Young added on Friday: "About the time the first practice starts this evening at Billown, it will start raining.

"It looks like could be a very difficult week next week and everyone involved in the TT will have to work very hard to fit everything in.

"There will be a mobile westerly which means once a weather system comes through there will be showers behind. 

"This will be a nightmare as the rain could last a couple of hours and move on before another weather front appears.

"There will also be issues with fog and mist as the warmer air will create low cloud.

"If I predict there will be rain at 10am the next day but it arrives at 9.30am or 10.30am I will be reasonably happy. But if you project that same level of accuracy days ahead that half an hour can become a few hours.

"Over the two weeks we will work through contingency planning with the organisers. Sometimes we will be in contact several times a day."

Despite a long period of warm and dry weather, the fears of TT fans that it would not last into the famous event look set to become a reality.

The Met Office forecaster also predicted that temperatures would fall to 14-15C, more normal weather for the time of the year.

On Saturday, the Isle of Man is forecast to experience heavy rain.
