Obervations of wind directions and air temperatures in Hornsund, Spitsbergen, in 1978—1985 were used to compute frequency distribution of wind directions and mean air temperatures at particular wind directions. Prevailing easterly winds (60°, 90° and 120°) resulted in lower air temperatures (to —2.2°C) than winter and spring means and in higher (nearly 1°C) than summer and autumn mean temperatures. Greatest positive deviations from mean seasonal temperatures are observed in winter at southerly and southwesterly winds and reach 10°C. Greatest negative deviations from mean seasonal temperatures are noted at northerly winds (330° and 360°) in autumn and reach —3.7°C.
