Tallinn aerodrome Climate handbook is a statistical analysis of the observations data provided by Tallinn Airport.
The handbook covers a 22-year period between 1997–2018, and contains the distribution of meteorological elements (visibility, cloud height, wind speed and direction, wind gust and direction, air temperature, air pressure, relative humidity, atmospheric phenomena, precipitation), and significant statistical parameters of aviation meteorology.
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.
