In the capital, Tbilisi, summer and autumn temperatures are warm with summer temperatures above 30˚c for most of July and August in the daytime and in the evening. Winters are generally quite dry and bright albeit cold and from November -March you will need a coat. April, May and June are warm but rainy and so a raincoat is strongly advised. The mountainous areas of Georgia can be considerably colder than Tbilisi even in July and August and so if you are planning on visiting Svaneti or Kazbegi for any length of time long trousers, hiking boots, a fleece and layers of clothing are necessary.
