The best time to go to Silba for pleasant weather and fewer crowds is during the shoulder seasons of late May to early June or September.During these periods, the weather is typically warm and sunny, ideal for swimming, sunbathing, and exploring the island without the intense heat of mid-summer. The sea temperature is comfortable for swimming, usually around 20-23°C. You'll find the island to be more peaceful, allowing for a relaxed holiday experience, and accommodation prices can be more favourable than in peak season.For those looking for a lively option and guaranteed hot weather, July and August are excellent. The island is at its busiest, with all restaurants and cafes fully open, and there's a buzz of activity. The sea is at its warmest, often reaching 25-27°C, superb for extended swims and water sports.
