The best time to visit Puerto Cayo is during the dry season, which runs from June to December.During these months, you'll experience consistently sunny weather with pleasant temperatures, typically ranging from 24°C to 30°C. This period offers the most reliable conditions for enjoying the beaches and outdoor activities like whale watching, which peaks from June to September. The ocean is generally calmer, making it ideal for swimming and snorkelling.For those looking for a more relaxed and quiet experience, the shoulder months of May and January can also be appealing. While there might be a slight increase in rainfall, the weather is still largely agreeable, and you'll find fewer visitors, often leading to better value on accommodation and activities.Ultimately, if you're seeking guaranteed sunshine and the full range of outdoor adventures, the dry season is your best bet.
