Orangeville is set for a sunny and hot start to the week, but the Environment Canada forecast shows a shift on the way. Monday, July 20, 2026, will bring sunny skies, a high of 24°C, and a humidex that makes it feel like 27. The UV index is expected to hit 9, which is considered very high.
When the UV index is in the very high range, sun safety becomes essential. Residents are advised to limit time in the sun, especially between 11 a.m. and 3 p.m. If you are heading outdoors, wear UV-blocking sunglasses, find some shade, and use sunscreen with regular reapplication every couple of hours.
The humidex reading of 27 means most people will feel only a little discomfort, but it is still warm enough that staying hydrated is a good idea. These conditions are right around what Orangeville usually sees in July, when the average high is 26°C and the low dips to 14°C.
A change in conditions is expected overnight, bringing a few showers and a risk of thunderstorms before Tuesday morning. On Tuesday, showers are likely with another risk of thunderstorms. The forecast calls for local rainfall amounts between 10 and 15 millimetres, a high of 23°C, and a humidex of 31. Cloudier skies and slightly cooler air are expected to settle in through the middle of the week.
For those with outdoor plans, Monday is the day to enjoy, but taking a few simple sun precautions will help everyone stay safe under the bright July sky.
