Greece: When to go
The Cradle of Western Civilization
Greece has a mild climate though the winters can be harsh up in the mountains. The best time to holiday in Greece is between April and June. The summer brings a lot of tourists to the country so it’s best to avoid the rush and holiday in an uncluttered atmosphere. In July and August the country has an influx of tourists and it becomes difficult to find accommodation anywhere. Winters are best avoided.
While the mountainous northern interior has harsh winters and brief summers, Southern Greece enjoys a relatively mild winter, with temperatures averaging around 55° to 60°F (13°-16°C) in Athens. Summers are generally hot and dry, with daytime temperatures rising to 85° to 95°F (30°-35°C), usually cooled by prevailing north winds (meltemi), especially on the islands, which often cool appreciably in the evenings. And at some point in most summers, usually July, the temperature will rise to over 100°F (38°C).
