  • Daily UV index: This is the most important factor. The higher the UV index, the stronger the sun’s rays and the higher the SPF you need. You can find the UV index for Jefferson County, Tennessee on the Environmental Protection Agency (EPA) website https://www.epa.gov/sunsafety/uv-index-applications
  • Skin complexion: People with fair skin, red hair, and freckles tend to burn more easily and need a higher SPF (ideally SPF 30 or higher). People with darker skin tones can generally tolerate the sun better but still need protection, especially at high UV indexes (SPF 15 or higher).

Here’s a general guideline:

  • UV index 0-2: Low risk, SPF 15 may be sufficient
  • UV index 3-5: Moderate risk, SPF 30 is recommended
  • UV index 6-7: High risk, SPF 30+ is recommended
  • UV index 8+: Very high risk, SPF 50+ is recommended

Additional factors to consider:

  • Time spent in the sun: If you’ll be on the lake for a long time, reapply sunscreen every two hours, even if it’s waterproof.
  • Sweating and swimming: Reapply sunscreen more often if you’re sweating or swimming a lot.
  • Reflective surfaces: Water reflects sunlight, so you’ll be exposed to more UV rays while on a lake.

Remember, even with sunscreen, it’s important to seek shade, especially during peak sun hours (10 am to 4 pm). Wear protective clothing like a hat and sunglasses for extra protection.
