location at the foot of the mountain. From there a road goes to Prionia, where the hike begins at the bottom of the mountain. Climate Generally speaking Olympus's climate can be described as Mediterranean with continental influence. Its local variations are the result of the impact of the sea and the rugged terrain of the region. In the lower locations (Litochoro and the foothills) the climate is typically Mediterranean, i.e. hot and dry in the summer, but humid and cold in the winter. Higher it is more humid, warm and sometimes severe, with more intense meteorological phenomena; in these locations it often snows throughout winter, while rain and snow is not unusual even in the summer. The temperature varies in winter from −10 °C to 10 °C and in summer from 0 °C to 20 °C, while winds are an almost daily occurrence. Generally the temperature falls 1 °C per 200 m of elevation. As the elevation rises, meteorological phenomena are more intense and the changes in temperature and humidity are often sudden. The coastal northeast slopes of Olympus receive more rain than the continental northwest, so, as a result, there is a clear difference in vegetation, being more abundant in the first of them. Hottest month is August, while coldest is February. The mountain's highest zone, over 2,000 metres, is snowcapped for about nine months (September to May). In some places the winds gather snow, 8–10 metres thick (anemosouria in Greek), while in some deep ravines the snow is maintained all over the year (everlasting snow). For this Olympus's alpine region, recordings have been made in the 1960s in the highest-elevation weather station in Greece, that was established on the summit of Aghios Antonios (2,815 m), providing a number of interesting data for the mountain's climate. The average temperature is −5 °C in winter and 10 °C in summer. The average annual precipitation heights vary from 149 cm at Prionia (1,100 m) to 170 cm at Aghios Antonios, about half of them rainfall and hailstorms in summer and the rest snowfall in winter. The weather may change several times in the same day. In summer rainfalls are frequent, commonly as evening thunderstorms, many times accompanied by hail and strong winds. However water springs over 2,000 metres are scarce and visitors should ensure that they have always water and of course the necessary clothing for any weather conditions. Flora The
