Extreme hot and cold weather and flooding events can have an adverse impact on public health, particularly for vulnerable people such as the elderly, the very young or those with pre-existing medical conditions.
It is likely that climate change will bring increasingly frequent flooding events, severe heat waves and extreme weather events, as well as a rise in sea levels. This advice is maintained year round. It may be used by anyone, including health and social care professionals. There is also advice for organisers of outdoor events and for those with child care responsibilities.
Public Health Wales acknowledges the significant contribution of Public Health England in the preparation of this advice.
Remember this advice can be used at any time, when anyone is feeling too hot, too cold or during a flooding event.
