Safety and preparedness

- Use broad-spectrum sunscreen of at least SPF 30 and reapply every two hours or after swimming or sweating.
- Wear a wide-brimmed hat and UV-protective sunglasses; seek shade during midday hours.
- Stay hydrated during humidex peaks and avoid prolonged strenuous activity outdoors when the humidex approaches the low 30s.
Breezy conditions, particularly Tuesday around midday, could produce gusts near 40 km/h; secure loose outdoor items and take care if driving high-profile vehicles.
