Future generations can look forward to sizzling temperatures of 40C (104F) on Sussex beaches as the summer months get hotter.

At the same time, holidaymakers will face much less chance of being caught in a downpour, according to the Government's weather predictions for 2080.

But the bad news is that winters will be much wetter as the effects of global warming begin to hit home.

A new document on climate change says Sussex and the South-East will be most affected by the changes expected over the next 80 years.

The temperature across Britain is expected to rise by between two and 3.5 degrees.

However, differences in global greenhouse gas emissions will lead to the South East becoming even hotter.

The chance of rainfall will decrease by 50 per cent during summer, according to scientists. But the chance of heavy rain in the winter will become "more frequent".

At the same time, sea levels are expected to rise by between 26 and 86cm in the South-East by the 2080s.

Ministers have published the research to allow businesses to prepare well in advance.

They also hope to focus people's minds on tackling global warming.

Environment Secretary Margaret Beckett said: "The change will be earlier and sharper than we thought and some of the change is already built in."
