Heat Health Alert

Year round planning is necessary so that longer term actions, such as those linked to spatial planning and housing, are taken to reduce the harm to health of significant hot periods when they occur. Should thresholds for an alert be reached outside of this period, an extraordinary health alert will be issued and stakeholders are advised to take the usual public health actions.

The Heat-Health Watch Service is designed to help healthcare professionals manage through periods of extreme temperature. The service acts as an early warning system forewarning of periods of high temperatures, which may affect the health of the UK public.

The Heat-Health Watch Service operates in England from 1 June to 15 September each year, in association with Public Health England. This is the period when temperature thresholds are most likely to be reached. However, should thresholds for an alert be reached outside of this period, an extraordinary heat-health alert will be issued and stakeholders are advised to take the usual public health actions.
