Try the following tips:

1. Stay out of the sun during peak hours. While these times may vary slightly depending on the season and where you live. You should be indoors if all possible between 10:00 and 15:00.
2. Keep covered up. Floppy hats and large umbrellas work well and so do cover-ups. Long-sleeved cotton shirts are excellent for hiking, cycling etc; see your sports store for special brands that allow breathing as well as cover-up.
3. Use sunscreen on any exposed areas. An SPF of  is recommended for it allows even the fairest skinned folks to stay out in the sun for a few hours before reapplying. Try chopstick on your lips. Follow the instructions on sunscreen carefully. Always reapply after leaving the water, as it'll have washed off.
4. Don't forget hard-to-reach places. Don't forget to cover the backs of your knees, back of your neck, elbows and back of your ears (if you have short hair). Feet should also be included if you are wearing sandals, flip-flops or going bare-foot. Even these places can hurt a lot with sunburn.
5. Don't lie in the sun purposefully seeking a tan. This is not only damaging to your skin but might burn you the first few times you try it at the beginning of the season. If you want to tan, do it gradually and sensibly, with short exposure and building up over time.
6. Put a small amount of oil or sunscreen in your hair so you will avoid burning your scalp. Or cover it with a hat. Some shampoos and hair conditioners contain SPF protection.
