You’ve no doubt seen these around the place… An anemometer is a wind speed measuring device that is commonly used by weather stations and individuals or institutions interested in measuring changes in the wind speed. To give the best reading, an anemometer is typically mounted on a pole positioned in an open space so that they are not obstructed by buildings or trees.

They often contain a set of three or four cup-like shapes that catch the breeze and spin at a speed proportional to the speed of the wind. Other smaller variations of these “weather-station” varieties include hand-held models that contain a fan or miniature propeller that works in a similar fashion.

In sailing, many yachts have wind instruments located at the top of the mast – clear of any obstructions. However, dinghies typically do not have the same equipment installed. An anemometer is not necessarily a requirement for laser sailing or dinghy sailing in general, but a hand-held version can be a handy piece of equipment. As these are not considered an expensive device, an anemometer may prove to assist you in selecting different sails or rigging based on the wind speed it measures. Or it can be just used for interest to see exactly how hard the breeze is blowing.

Whatever your use, there are quite a few handheld anemometers that work well and are very reasonably priced. Here is a closer look at selected portable models of anemometers that are available for purchase online:

The accuracy is said to be within 0.1 dgts with quick measurements to assist in determining conditions at any given moment.

There are many different functions built into this wind gauge. In addition to reading wind speed, this handheld device provides temperature and wind chill readings. All data is shown on an LCD display. Wind speed can be read in m/s, km/h, ft/min, knots and mph measurements.

Extras include adjustments to read the temperature in either °F or °C and you can record and recall conditions. They include maximum, minimum, average and current temperatures. There is also a low battery indicator and a built-in screw hole permits attachment to a lanyard.
