As we move through summer towards autumn, the weather can change quickly. These weather changes can create fascinating photographs, but how do you predict weather and make sure you are prepared in advance. Kestrel handheld weather meters make this easy supplying a huge amount of data that not only give instant readings but helps to predict future weather patterns.

Richard Paul Russell Ltd have recently supplied independent photographers, it seems the Kestrel is popular due to its size and ability to fit in an users pocket.

The Kestrel 4000 seems to be the meter of choice measuring a wide range of weather parameters including temperature, relative humidity, barometric pressure, wind speed, dew point, heat index, wind chill and more. It even logs data at set intervals and produces graphs so you can track trends. It runs on two AA batteries that last a long time. The unit starts up quickly and the controls are quite responsive. There’s a built-in backlight so you can read it in the dark without a flashlight. Its waterproof and it floats.

In remote areas the Kestrel comes into its own. If you are unable to get a local forecast the Kestrel 4000 will quickly give you previous and current barometric pressure readings so you can predict future patterns. If the wind shifts direction or it looks threatening you can review its logs to gauge what might be coming your way. If the weather is awful but the barometric pressure starts to rise sharply you can assume it’s going to clear up soon.

Barometric pressure depends on knowing your altitude. The Kestrel actually measures station pressure, the actual pressure the air is currently pressing down with at your location. To convert this to true barometric pressure it needs a reference altitude, something that can be easily obtained with a GPS or from a local airport.

Kestrel meters are extremely useful for outdoor photographers and for anyone who needs accurate weather information when out in the wilderness.
