The best time to visit Serifos for a vacation rental is during the vibrant summer months, particularly in July, when the island truly comes alive. This is peak season, spanning from June to August, and it's ideal for travellers seeking sun-soaked beaches, crystal-clear waters, and a lively atmosphere. July offers warm temperatures, often reaching the low 30s Celsius, making it superb for enjoying outdoor activities, such as swimming, sunbathing, and exploring the charming villages scattered across the island.
During this bustling period, visitors can indulge in the local culture at various festivals and events, while enjoying the delicious cuisine at seaside tavernas. The island's famous beaches, like Livadakia and Agios Sostis, are superb for relaxation and socialising with fellow adventurers.
If you're looking for a more budget-friendly option, consider visiting in November. While this is outside the main tourist season, you can still enjoy the stunning landscapes and peaceful atmosphere that Serifos offers. The weather is milder, with temperatures in the low 20s Celsius, which can make for pleasant hiking and exploration of the island's natural beauty without the summer crowds.
