Temperatures had climbed into the 30s well before any mad dogs or Englishmen could venture into the noonday sun today.
With highs to rival the Med predicted today the heatwave quickly lived up to its promise with only light winds to ease the conditions.
Temperatures in Thetford had already hit 31C by 11.45am, while Bury St Edmunds, Newmarket, Sudbury and Haverhill were only a degree cooler, according to the Weather Channel, while Diss was a comparatively mild 29C.
But by the end of the day all are expected to reach 32C, except Bury which is expected to be a couple of degrees warmer.
It made the 28C recorded at the Wattisham weather station at the same time seem almost cool, but hinted you were better off even if you were only a few miles closer to the coast.
In fact, if you want to keep your cool, head down the A14 to Felixstowe where by noon the temperature was only 22C and its high for the day was expected to be 10 degrees lower than Bury’s.
Norfolk Police issued a heatwave warning to anyone attending Royal Norfolk Show today and tomorrow, urging them to take food and water with them as they faced sitting in traffic in high temperatures.
Suffolk Police and Fire Service jointly Suffolk Police issued water safety advice becauise of the heat and following the recovery of man’s body from Alton Water reservoir yesterday.
They urged people not to cool off by jumping or diving into rivers because quick entry into cold water can cause your body to go into shock.
You will also be unable to judge the depth of water just by looking and there could be submerged hazards such as weeds, rubbish or pollution.
There may be strong currents, which could pull you downstream or under the surface of the water.
They say not to assume because you can swim in a pool that you can deal with the challenges of open water swimming. Swim in safe areas, or where there is supervision and/or a lifeguard and never go into the water after drinking alcohol.
Temperatures in the high 20s and low 30s are expected to last through the weekend with thunderstorms on Saturday and showers on Sunday.
