How to cope with a heatwave
The hot weather's here at last, but do you know how to keep cool in a heatwave?

This year, the Department of Health has published a Heatwave Plan to let people know what they can do and what to watch out for.

Why can heat be dangerous?

Excessive heat can:
  • Increase heart problems
  • Raise breathing problems
  • Cause heatstroke

What makes a heatwave?

There are four different heatwave levels.

- Level 1 - Green: This is the 'normal' state, where there is no more than a 50% risk of heatwave. People should just be aware of the risks of heat and the need to keep cool.
- Level 2 - Amber: Alert and readiness - there's now a 60% chance that 'threshold' temperatures will be reached for 2 or more days. 'Threshold' temperatures vary from region to region around the country, but are around 30°C during the day and 15°C at night.
- Level 3 - Red: Heatwave action - this stage is reached when threshold temperatures have been reached in at least one region around the country.
- Level 4 - Red Emergency: When the Heatwave Plan hits 4, the situation is extremely serious - this is when the heatwave is so severe that it's likely to cause power or water shortages.

Practical tips for a heatwave

  • Check up on friends, relatives and neighbours who may be less able to look after themselves
  • Shut and shade windows when it's hotter outside and open them for ventilation when it's cooler outside
  • If you're vulnerable to the effects of heat, avoid going out between 11am-3pm
  • Drink cold drinks like water or fruit juice regularly and avoid tea, coffee and alcohol
  • Stay tuned to the weather forecast and plan ahead with supplies
  • Keep plenty of water to hand and stay in the shade where possible
  • Identify the coolest room in the house

What homeowners can do

Homeowners can take other practical steps to stay cool during the summer, including:
  • Shading south and west-facing windows
  • Painting buildings and surrounding walls white to reflect heat
  • Planting small trees and shrubs around buildings
  • Replacing metal blinds with curtains with white linings to reflect heat outwards where possible.
