A dangerous heat warning remains in effect across Norfolk County as temperatures and humidity levels continue to rise, making this the first significant heat wave of the season. Daytime highs are expected to range between 33–36 °C, with humidex values reaching an oppressive 42–46. Even nights will offer little respite, as temperatures only drop to 22–25 °C through Tuesday night.
Extreme heat can affect everyone, but especially seniors, those with chronic illnesses, people living alone, and young children. Health authorities advise residents to remain vigilant for signs of heat exhaustion, including headaches, dizziness, fatigue, dark urine, and thirst. At the first signs of trouble, rest and rehydrate immediately.
More serious is heat stroke, which is a medical emergency. Symptoms can include confusion, hot and red skin, intense nausea, and loss of consciousness. In such cases, call 9‑1‑1 right away and attempt to cool the person down by moving them to a shaded area, applying ice packs, and removing any excess clothing.
Residents are urged to drink water regularly (even when not thirsty), limit exposure to direct sun, and wear lightweight, light-coloured clothing and wide-brimmed hats when outside. Use fans or air conditioning when available, and consider seeking cooler spaces like libraries, community centres, or shaded parks. Never leave children or pets in parked vehicles.
With temperatures and humid conditions set to continue until Tuesday evening, public health authorities recommend checking in on elderly or isolated neighbours, limiting outdoor activity to cooler times of the day, and following official guidelines to stay safe throughout the heat wave.
