10+ Very high, sunburn can occur in less than 15 minutes

SPF recommends that when applying sunscreen to exposed areas of your skin that you apply it in lower indexes every 2 hours. During higher temperatures, you will want to apply it more often due to perspiration, around every half hour. We recommend this because when you are out in the heat, you perspire and your sunblock can wear off quicker than what the bottle states. Sun protective is beneficial in not having to apply in hard to reach areas. If you are in the water, you should apply sunscreen to exposed skin ever 20 minutes, even if it says waterproof, we still recommend it to be safe.
