When do UVB rays reach their maximum levels?

UVB rays, which are responsible for causing sunburn and contributing to skin cancer, have their maximum levels during the summer months when the sun is highest in the sky. June specifically marks the onset of summer in the Northern Hemisphere, leading to the longest days and most direct sun exposure. During this time, the angle of the sun allows for stronger UV radiation, making it crucial to take protective measures against overexposure.

In contrast, the other months mentioned typically coincide with lower sun angles or seasonal changes that result in reduced UVB intensity. In June, individuals are at a higher risk for UV-related skin damage due to the substantial increase in UVB radiation, which is why this period is emphasized for sun safety awareness and protection.
