Heatwave Plan for Wales
Extreme heat conditions are dangerous to everyone, with temperatures in Wales of 30oC or more during the day and 15oC or more during the night, regarded as having the potential to adversely affect health and well-being, particularly amongst more vulnerable population groups. The public health risks associated with extreme heat and heatwave conditions are significant and include dehydration and hyperthermia, which can further lead to shock, organ failure and even death.
Whilst Wales has a temperate climate with temperatures usually not getting too hot or too cold, extreme heat conditions and heatwaves can occur. In a heatwave in 2003, the UK experienced its hottest weather on record when temperatures were thought to be the highest in Europe for around 500 years. This hot spell resulted in over 2,000 excess deaths across England and Wales and pushed deaths among people aged over 75 years up by 60%.
In view of the impact that conditions of extreme heat can potentially have on public health and the fact that most heatwave-related illness and death is preventable through prompt and effective actions, the Welsh Government has developed this Heatwave Plan for Wales.
It aims to enhance resilience in the event of a heatwave and to reduce the risks to health associated with extreme heat by alerting appropriate health, social and other care staff and members of the public (especially vulnerable groups) to the dangers of excessive heat.
