The best time to go to Arraial Do Cabo is during the dry season, which runs from April to October, with May to September offering the most consistently pleasant weather.During these months, you'll experience less rain and more sunshine, making it ideal for enjoying the stunning beaches and outdoor activities Arraial Do Cabo is famous for. The sea is generally calmer and clearer, superb for snorkelling, diving, and boat trips to explore the region's natural beauty.For those looking to avoid larger crowds and potentially find better value on accommodation, visiting just outside the peak school holiday periods within the dry season, such as May, June, or September, can be particularly rewarding.
