The best time to go to Othonoí is during the shoulder seasons, specifically late May to June or September to early October. These periods offer comfortable weather, fewer crowds, and pleasant conditions for exploring the island.
During these months, the average temperature is warm but not excessively hot, typically ranging from the mid-70s to low 80s Fahrenheit (24-29°C). The sea is also warm enough for swimming and water activities, making it ideal for couples or solo travelers looking to enjoy the island's natural beauty without the peak summer rush. You'll find it easier to secure accommodations and enjoy a more relaxed pace.
July and August are the warmest and busiest months, with temperatures often exceeding 90°F (32°C). While all services are available, the island can feel crowded, and prices for accommodations and activities are at their highest. This time of year works well for families who are restricted to summer travel and enjoy a lively beach atmosphere.
Conversely, the winter months, from November to April, are much cooler and quieter. Many businesses close for the season, and ferry services are less frequent.
