Visitors should research these differences to maximize their enjoyment based on seasonal offerings.

  6. UV Radiation Levels:
    UV radiation levels indicate the intensity of ultraviolet light from the sun, which can lead to sunburn and skin damage. Due to high elevation, UV radiation can be more intense at the Grand Canyon. The Environmental Protection Agency states that UV exposure increases by 4% for every 1,000 feet ascended. Therefore, visitors should apply sunscreen and wear protective clothing, especially during midday hours.

  7. Weather Alerts and Warnings:
    Weather alerts and warnings are notifications issued by local authorities regarding severe weather conditions such as storms or extreme temperatures. The National Weather Service frequently updates alerts that can impact safety in the park. Visitors should check conditions regularly, listen for alerts, and be prepared to change plans if necessary for their safety.

By being aware of these additional weather considerations, visitors can enhance their safety and enjoyment while exploring the Grand Canyon.
