Kos Climate & Weather
Kos Climate Chart
Kos experiences hot, dry summers and mild winters, much like other Greek islands. Temperatures are hottest in July and August, when they range from 82ºF (28ºC) during the day to 72ºF (22ºC) at night. Conditions can get substantially hotter during heat waves. Rainfall is almost non-existent in summer, bar a few showers between October and March.
Summer is the most popular time to visit, though late spring and early autumn may be better options for travellers who dislike very warm conditions. Springtime visitors will find the island fresh and lush, and the seas warm enough for swimming. The ocean is pleasantly warm in autumn too. Visitors will find far smaller crowds during both shoulder seasons.
