Summary

  • More parts of England are expected to be declared in drought ahead of the fifth heatwave of 2026 - this map shows the current state of play

  • The National Drought Group, which is made up of regulators, government officials, water companies and agricultural bodies, is meeting later to decide on the areas - an announcement will likely follow

  • All of Wales and more than half of England are already in drought - new images show parched grassland and dried up reservoirs

  • Scotland doesn't declare in the same way and instead monitors "water scarcity", while there are no official droughts currently in Northern Ireland

  • Continued dry weather across the country has had an impact on water supplies, with 23 million people already under hosepipe bans

  1. Warnings of impact on health care ahead of fifth heatwave

    The UK Health Security Agency have just upgraded the heat health alerts to Amber for most of England from Tuesday to Friday.

    They warn that significant impacts are likely across social and health care services due to high temperatures.

    Impacts are likely for those over 65 or with health conditions but there may also be impacts to younger age groups too.

    Amber alerts are in place for all regions of England, aside from the North East, which is under a Yellow alert for the same period.

    The heatwave will start to develop from Tuesday and then intensify for many, peaking on Thursday or Friday.

    And just as we saw during the June and July heatwaves, it will be extreme for some with temperatures into the mid-30s Celsius.

    The hottest weather on Tuesday is likely to be across the Midlands, central southern England and east Wales where temperatures will rise to 28 to 30C.

    By Wednesday the heat will spread more widely across England and Wales, with temperatures widely 30 to 32C.

    Then by Thursday, even hotter still with the temperature exceeding 35C for some in the Midlands, eastern and south-east England.

    The heat will persist on Friday for most but turning less hot across western areas - and then for all over the weekend as the heatwave eases.

    Heat health alerts have been upgraded to amber for most of England, except the North-East, from 09:00 BST on Tuesday to 21:00 on Friday.

    The alert warns that significant impacts are likely across health and social care services due to the high temperatures, including a rise in deaths, particularly among those aged 65 and over or with health conditions.

    We'll bring you more on this shortly.

  3. The Environment Agency uses four stages to assess drought or water shortage

    As we mentioned in our last post, there is no single definition of drought.

    Caused by a shortage of rainfall, the characteristics of a drought - things like timing and duration - will vary.

    To determine an area's level of drought, in England, the Environment Agency will look at a number of factors including rainfall, river flows, groundwater levels and and public water supplies.

    It uses four stages to assess what response is needed:

    • Prolonged dry weather - which begins to impact river flows, groundwater levels and water levels in lakes and reservoirs
    • Drought - further deterioration to the environment with consequences for agriculture, people and businesses
    • Severe drought - prompting widespread and lasting effects on the environment, farming, people, communities, and the economy
    • Recovering from drought - the impacts on the environment are reducing

  4. How is drought defined?

    There is no single definition of drought, but it usually refers to a period of prolonged unusually dry weather that can have impacts on people, nature and the environment.

    The Environment Agency says some droughts are short and intense, caused by a hot and dry summer, while others are long and develop over multiple seasons due to low rainfall.

    It also highlights different types of drought. They include agricultural drought when there isn't enough rainfall to support crops and farming, and water supply drought when companies have concerns about supplies for their customers.

    Natural Resources Wales agrees that "every drought is different", adding that some affect large areas while others are more concentrated.

    It says it declares drought when a combination of indicators show a "significant shortage of rainfall and water availability", impacting things like rivers, groundwater, ecosystems and agriculture.

  5. UK set for another hot week with possible highs of 36C

    The UK has experienced unusually high temperatures in recent months and heat is set to once again build throughout the week as a fifth heatwave is likely to be declared.

    Monday will provide a bit of a break from the intense heat - with maximum temperatures in northern areas of the UK around 18 to 24C and further south temperatures between 22 to 27C.

    However, temperatures are then set to soaracross much of England and Wales.

    By Tuesday, warmer air will start to move back in across the UK with the highest temperatures across central southern England, the Midlands and east Wales.

    Yellow heat-health alerts remain in force for much of England until 21:00 BST on Tuesday, though they are likely to be extended or upgraded as the heatwave nears.

    Wednesday will see temperatures widely across England and Wales head into the high twenties and low thirties.

    Temperatures are due to peak on Thursday with possible highs of 36C (97F) in south-east England, and up to 35C likely across central and eastern England.

  7. Which areas are currently in drought?

    Drought has already been declared in large parts of England, as well as the whole of Wales.

    The Environment Agency - which made the announcement for England - said in its latest update that the week from 31 July to 6 August was the "seventh consecutive week of less than 10mm of rainfall across England".

    Areas in the east and south-east saw less than 1mm, it added.

  8. Parched ground and dried up lake beds across England

    With drought already declared across half of England, its effects are quite visible across the country.

    Photographers have captured dried up reservoirs and arid land around famous landmarks across England and Wales.

    The National Drought Group is meeting later today, to decide whether more regions will be declared as being in drought.

    The group is made up of regulators, bodies such as the Environment Agency, government officials, water companies and agricultural bodies.

    Today's meeting comes as England and Wales brace for a fifth heatwave, while nearly two months without significant rainfall have placed growing pressure on water supplies and seen 23 million people subject to hosepipe bans.

    Half of England and the whole of Wales is already officially in drought.
