These Meteorological Observations are an important accurate record of the local weather since the decades. They are part of Flagstaff Hill's Meteorological Observations collection of over seventy record books dating from the late 19th century.

Anemometer
This device was used to measure surface wind speed and direction. This anemometer was located on a concrete pad outside room 2.15 on a steel pole. The pole was considered unsafe and the anemometer was relocated to it's current position. When lowering the pole it fell over and was badly damaged. The Bureau of Meteorology donated it to the museum. It was then repaired and restored. The central pole on which it is mounted is galvanised iron pipe painted black. The anemometer, a portable device that manually measures wind speed, was a necessary instrument once common to all weather stations. The arms are attached to a vertical rod and as the wind blows, the cups rotate, making the rod spin. The stronger the wind blows, the faster the rod spins. The anemometer counts the number of rotations, or turns, which is used to calculate wind speed, surface wind and direction. They were designed to be durable to withstand the corrosive environment and strong winds expected at coastal sites such as those at Gabo Island. Anemometers existed in the nineteenth century and their design was improved by various experts including John Robinson in 1846, John Patterson in 1926, Brevoort and Joiner in 1935 and Derek Watson in 1991 who added wind direction measurement to its functions. This example was made for the Bureau of Meteorology by the Melbourne instrument company, Synchrotac, which became registered and incorporated on 26 July 1966. It is now displayed inside the building. A good example of its kind, the anemometer has first level contributory significance for its historic value and provenance to the lightstation.Anemometer and tripod stand. Three cupped brass discs on rotating arms fixed to turned brass cylinder shaped shaft. Beneath discs is a lead directional wind arrow attached to a rotating arm. A wooden three legged stand with central supporting pole of black painted hardwood and attached to a white painted marine ply circular base.Under wind cups: " SYNCHROTAC / MELB. / ser.no.70/372 / MADE IN AUSTRALIA." Above wind direction arrow: "C.OF.APT..../ SYNCHROTAC / MELB ? MADE IN AUSTRALIA / ser.no.70/372"
