Winter fairytale at Hvar Observatory

Written by Jaša Čalogović Thursday, 01 March 2018 00:00

snow hvar2018Snow at Hvar and other islands in Dalmatia is quite rare and it happens just for a short time usually once in few years. Cold weather in Europe at the end of February followed with north and cold wind Bora was the reason for snow on Hvar and other nearby islands. It is quite strange to experience Hvar in such white winter atmosphere and we publish several pictures from 27 February to illustrate that.
