The best time to visit Cades Bay is during the dry season, which runs from December to May, offering warm, sunny weather and calmer seas.
During these months, you'll experience consistently pleasant conditions, ideal for enjoying the beaches, water sports, and outdoor activities. The sea is typically tranquil, making it superb for swimming, snorkelling, and sailing around the bay. This period is particularly good for couples looking for a relaxing escape with reliable sunshine.
While the dry season is popular, for those who prefer fewer crowds and don't mind the occasional shower, the shoulder months of June and November can also be a good option. You might find slightly better value on accommodation during these times, and the island remains beautiful, albeit with a higher chance of rain.
