England and Wales provisionally recorded their driest July since records began in 1836, according to the Met Office. England received just 6.5mm of rainfall — roughly 10% of its long-term average for the month. The previous record, set in 1911, was 13.4mm. Wales recorded 9.3mm, about 9% of its average. Southern England was hit hardest, seeing only 1.9mm, a mere 3% of what it normally gets in July.

Nineteen English counties recorded one millimetre of rainfall or less across the entire month. July 2026 was also the sixth month in a row to post above-average temperatures in England, making it the second-warmest July on record for the country. Wales posted its joint-warmest July for mean temperature. The Met Office confirmed that southern and eastern regions were especially dry, with southern England reporting its driest July in a data series stretching back to 1836 The Guardian.

By mid-July, the situation was already serious. The UK had received just 42% of its average summer rainfall by that point, and the country had already surpassed the total number of days above 30°C recorded in all of 1976 — a year long used as a benchmark for British heatwaves Met Office. Earlier in the season, 2026 became the first year on record to reach 35°C in the UK during May. By 31 July, England was tracking just 5.6mm of rainfall, 8% of its long-term average. The BBC reported that England and Wales were on course for their driest July in roughly 190 years of records BBC.

The water consequences followed quickly. In the week before 3 August 2026, half of England and the whole of Wales were officially declared to be in drought. About 40% of England's population was placed under a hosepipe ban during the same period The Guardian.

It is natural to compare this to England's 1976 drought, which remains a reference point for policymakers and water managers. In 1976, a prolonged dry spell from spring through summer led to standpipes in streets and emergency water rationing. But the comparison is imperfect: 1976's severity came from an extended rainfall deficit over many months, whereas 2026's July record reflects an extreme single-month failure layered on top of an already warm and dry first half of the year. Think of it as the difference between a slow, steady drain on a bathtub and a sudden, near-total shutoff of the tap — both leave you short, but through different mechanisms.

The six consecutive months of above-average temperatures in England through July matter here because warm air increases evaporation — what scientists call evapotranspiration, the combined loss of water from soil surfaces and plant leaves. Higher evaporation rates compound the rainfall deficit, accelerating the drying of soils and the drawing down of reservoirs beyond what the rainfall numbers alone would suggest.

Drought declarations in England are not symbolic. They are determined by the Environment Agency in consultation with water companies, and they trigger specific operational responses within those companies' drought plans. These include reducing water pressure in distribution networks, ramping up leak detection, and accelerating supply-side measures such as connecting reservoirs to one another or, in extreme cases, obtaining emergency licenses to draw water from sources not normally used. Hosepipe bans — formally called temporary use bans under the Water Use (Temporary Bans) Regulations 2010 — restrict households from using hosepipes to water gardens, wash cars, or fill paddling pools. With 40% of England's population now affected, the geographic reach of these restrictions exceeds what was seen during the 2022 drought, when similar measures were introduced but covered a smaller, more concentrated area.

The broader context here is the trajectory of summer 2026 as a whole. The early-season milestones — reaching 35°C in May for the first time on record and surpassing 1976's total count of days above 30°C by mid-July — indicate that the heat driving the drought was not confined to one anomalous month. The consecutive months of above-average temperatures from February through July created conditions that primed the water system for a severe response when July's rainfall nearly failed entirely. Reservoir levels, soil moisture, and river flows entering August reflect the cumulative effect of that six-month warm spell, not just the July precipitation figures now dominating the headlines. Water companies and the Environment Agency will be modelling these layered deficits as they decide whether to escalate drought severity in the coming weeks — particularly if the dry pattern continues into August and early September, which are typically low-rainfall periods anyway.
