And the sun shone and shone. The spring had been warm, but from mid-June to mid-July the heat was almost unbearable. Crops wilted in the fields, Cheshire ambulancemen were disciplined for taking off their ties, Heathrow flights were cancelled after overheated check-in staff refused to serve bad-tempered passengers, forest fires ravaged North Yorkshire, Inverness-shire and Surrey, British Rail stopped washing trains, workers at Aston Martin in Newport Pagnell began work at 6.30am to beat the heat.
It rained on St Swithin's Day (15 July), but the respite was brief, and serious high temperatures resumed in August.
Besides the heat, there was drought. 1975 had also been hot and the winter between saw little rain, so reservoirs were low before the heatwave started. By July many were dry and cracked as an American desert and emergencies were being declared all over the country. Anglian Water suggested that customers put a brick in their lavatory cistern to conserve water, while Thames Water urged them to brush their teeth from a mug rather than a running tap. In South Wales, a grocery chain imported French bottled water but failed to impress - housewife Molly Rodgers of Cardiff declared: 'Anyone who would pay 27p for a bottle of water must be out of their minds.' Periodically, the shortage would prove too much and supplies for tens of thousands were restricted to stand-pipes in the street.
Most notorious of all were the hosepipe bans, imposed in a record 33 counties. Britain became a nation of furtive waterers, dousing the flowerbeds and lawns under cover of darkness. An exasperated toff in a classic Marc cartoon in the Times remarked to his wife: 'Damn gardener wants overtime for working nights.' Many insisted they would water on while they could see sprinklers at work in broad daylight in parks, cricket grounds, golf courses, racecourses and the like.
James Callaghan's government, still in its first few months, did not shine. No one expected the heatwave to last so a sense of urgency was slow to build, and it did not help that when MPs finally debated the drought the sprinklers were playing on the grass outside in Parliament Square. On 14 July a Drought Bill was introduced to restrain unnecessary water use, but it was too little, too late.
By late August industry was facing a crisis and Len Murray, the TUC chief, coined a characteristic catchphrase: 'Save Water, Save Jobs'. In South Wales, plans were being laid to ship in water from Ireland, while the Central Council for Physical Recreation was hiring tankers to deliver watery effluent from sewage plants to playing fields.
On 24 August Denis Howell was appointed Minister for Drought. This was to prove one of the most effective political appointments ever, for a week later, to universal delight and relief, it finally rained.
