Hour-by-hour Devon weather forecast for another very hot day

Thursday sees yet another prediction of incredibly hot weather across Devon.

With a Met Office ‘amber warning’ for extreme heat being issued just days ago, today is, according to the Exeter-based weather forecasters, the final day of the unbroken sunny spell.

As the beaches and beauty spots keep getting busier, tourists and locals alike have flocked to the waters to cool off.

With highs of nearly 30°C in some areas of the county, today’s weather matches the past few days’ low humidity and scorching hot sun.

Devon and Cornwall Police has warned of wildfires, urging caution during the current hot weather.

Unlike the last few days, however, there is some cloud cover to break up the constant sunlight.

In some areas, the sun is only due to be exposed for half of the day – a far cry from the unbroken blue skies of the past working week.
