The Met Office has advised on what to expect including adverse health effects (sunburn and heat exhaustion) and, as people flock to the coast to cool off, an increased risk in water safety incidents.

There's also a chance of delays to road, rail and air travel.

The Met Office's twitter profile says this is the first ever 'extreme heat warning' issued.
