Heat health alerts
The alerting system provides an early warning when adverse temperatures are likely to impact on the health and wellbeing of the population.
The Weather health alerting system is provided by the UK Health Security Agency (UKHSA) in partnership with the Met Office. It's intended to provide early warning to the health and social care sector, the responder community, the voluntary and community sector and government departments when adverse temperatures are likely to impact on the health and wellbeing of the population. The Weather health alerting system is made up of the Heat-Health Alerts (HHA) and Cold-Health Alerts (CHA). The Weather health alerting system underpins the Adverse Weather and Health Plan.
The Heat-health alerting systems core alerting seasons runs from 1 June to 30 September each year. However should an episode of heat occur outside of this core period, an extraordinary alert will be issued. Make sure you are registered to receive the alerts directly by email by completing the registration form.
