A Met Office spokesperson said: “More people are likely to visit coastal areas, lakes, rivers and other beauty spots leading to an increased risk of water safety and fire-related incidents. 

“Some delays to road, rail and air travel are possible, with potential for welfare issues for those who experience prolonged delays. 

“Temperatures will increase across much of the UK over the coming week. Temperatures will be highest across parts of England and Wales with these peaking on Friday and Saturday.  

“In addition to high daytime maxima, temperatures overnight will remain very warm, especially in larger urban areas.”
