Temperatures in Rio, where the closing ceremony of the Olympic Games was held on Sunday 21 August, will be cool in comparison rising from 21°C on Tuesday to 23°C on Thursday.

Ibiza will bask in temperatures around the 30°C mark all week while Kingston, Jamaica, will be cooler than parts of the UK with the mercury reaching 31°C by the end of the week.

"Through the week ahead, we will see warmer temperatures across many southern areas of the UK as we draw in warm air from the continent," a Met Office spokesperson said.

"By Tuesday and Wednesday, temperatures in the south-east may reach 29C, which will feel very warm if not hot. Sunshine will accompany the high temperatures but with rain across some northern parts.

"The south-east is expected to see the highest temperatures with it feeling cooler and fresher the further north you go."
