If you have been outdoors today – you know how hot it is.  The Environmental people report that this is what it is going to be like for three days.

Halton Region Public Health has issued an Extended Heat Warning starting July 28, 2025 for Halton Region as a result of Environment Canada continuing its Heat Warning. An Extended Heat Warning is issued when the daytime temperatures are expected to reach at least 31 degrees Celsius with overnight temperatures above 20 degrees Celsius for three or more days, or when the humidex is expected to reach 40 for three or more days.

Exposure to these weather conditions can cause serious health problems those especially at risk include: older adults, infants and young children, people who work and exercise in the heat, people without adequate housing and those without air conditioning. People who have breathing difficulties, heart problems, kidney problems or are taking medication that affect their sensitivity to heat are also especially at risk of preventable heat illness. This warning is intended to inform the general public and community agencies, to keep residents safe and healthy during the heat and to recommend that precautions are taken when temperatures are high.

As the climate changes, heat events are expected to become more frequent, longer and hotter in Halton Region and other parts of Ontario.

Heat stroke is a medical emergency. Call 911 if you are caring for someone who has a high body temperature and is either unconscious, confused or has stopped sweating. Cool the person as best you can while waiting for medical attention to arrive.

Too much of a good thing – be careful.

You can prevent heat-related illnesses by avoiding strenuous outdoor activities; seeking shade from the sun; spending time in air-conditioned places, such as shopping malls and community centres; and staying hydrated. Call or visit friends and neighbours who may be at risk and never leave people or pets in your care unattended in a car.
