The Runway Visual Range minium values below 200 m were measured only at few observational occasions in April, June and September. The occurrence frequency of horizontal visibility below 1500 m and/or cloud ceiling below 500 ft is the highest during winter months and the lowest during summer months.
The prevailing wind direction in spring and in summer is 260-280 degrees, whereas in autumn and in winter it is 200-220 degrees. Wind speed is mainly 6-10 knots.
Most frequent weather phenomena are rain mist, and snowfall.
A similar climate handbook was published in 1969 and a short version in 1975. A climate handbook for Kuressaare Airfield was published in 2022 and for Tartu Airfield in 2021.
