Understanding the UV Index is crucial for residents of Sainte-Catherine, Canada, where sun exposure can vary significantly throughout the day. Being aware of UV levels is key in preventing sunburn and promoting long-term skin health. With a Dfb climate, the region experiences warm summers, which means that peaks in UV exposure, reaching up to 9 around midday, pose a greater risk for harmful effects.

With this trajectory, it's crucial to take precautions during the peak hours of 11 AM to 1 PM, ensuring skin protection against harmful UV rays. Stay safe and enjoy the sun wisely!
