All boomerangs are affected by the wind, some more than others. Wind is the force that will bring your boomerang back to you or blow it away from you. You must learn each boomerang's characteristics and always be aware of the wind speed and direction. For right handed people, the boomerang is thrown usually between 30-90 degrees to the right of the wind heading. For left handed people, that is 30-90 degrees to the left of the wind heading See the Boomerang Manual.

Estimating the Wind with the Beaufort Scale Learn how to determine the wind speed. This Beaufort Scale is modified for judging the wind on the land.
Wind Speed	Beaufort Category	How to Judge the Wind
1-3 mph	Light Air	Smoke drifts. Wind cannot be felt.
4-7 mph	Light Breeze	Wind felt on face. Leaves rustle. Weather vanes move.
8-12 mph	Gentle Breeze	Leaves and twigs in motion. Light flags are extended.
13-18 mph	Moderate Breeze	Wind raises dust and loose papers. Small branches move. Flags flap.
19-24 mph	Fresh Breeze	Small trees in leaf sway slightly. Wavelets form on ponds and lakes.
25-31 mph	Strong Breeze	Large branches move. Telephone lines sing.

Summer can be deceptively hot. Here is a heat index calculator

Get the current conditions from your local Weather section. Then enter the values below:
Temperature (70°F - 140°F)	Relative Humidity (0 - 100%)	Heat Index (°F)

Note: The formula used to calculate the heat index gives only an approximation because of the complexity of human and environment interaction.
