Residents in Hanover, Ontario can expect a stretch of hot and sunny weather this week, with daytime highs climbing well above normal and very high UV index levels prompting reminders to stay sun safe.
Environment Canada‘s forecast for Monday, July 6, 2026 calls for sunny skies, becoming a mix of sun and cloud in the afternoon, and a high of 28°C. With humidity, it will feel more like 32. The UV index is forecast to hit 8, which is considered very high. On Tuesday, the UV index is expected to reach 9, the highest level for the week, with a humidex of 33.
These temperatures sit above the seasonal norm of 24°C for this time of year. While it won’t be as extreme as the recent heat wave that pushed temperatures into the mid-30s across Ontario over Canada Day, the combination of heat and intense sun still requires caution.
At UV index levels of 8 or higher, Environment and Climate Change Canada advises limiting time in the sun, especially between 11 a.m. and 3 p.m. Wearing UV-protective sunglasses, staying in the shade, and reapplying sunscreen every two hours or after swimming or sweating are strongly recommended. Unprotected skin can burn quickly on clear, sunny days.
A chance of showers returns to the Hanover area on Thursday, but the rest of the week looks ideal for outdoor activities, provided residents take the right precautions against the sun.
