The SPF rating should vary according to a person's skin type. The sun is strongest between 10 a.m., and 3 p.m., although burning can occur even in the early morning or late afternoon.
Extra protection is needed during peak hours.
Overcast days should not be taken lightly. Ultraviolet rays can burn through fog or haze. Even when working and playing outdoors, the skin needs protection against the sun. Many common outdoor surfaces including sand, road, cement and water reflect and intensify the sun's rays. The sun's rays pass through and reflect off the water, increasing sun exposure.
