On a trip to the beach, what can I do to prevent getting sun burned?

Here are some things you can do to prevent being sun burned at the beach:
- Don't go to the beach if the UV is over 7
- Bring a tent to the beach so you can be in the shade
- Wear strong sunscreen and reapply it regularly
- Wear SPF protected long sleeve shirts
- Wear a hat to cover your head and face
