Rainfall is minimal, ensuring that boat tours and visits to historical sites are less likely to be disrupted. It's an ideal time for couples and families looking for a relaxed and predictable travel experience.While the dry season is optimal, the shoulder months of October and February can also be good choices. During these months, you might encounter occasional rain showers, but they are usually brief, and the weather remains generally pleasant.
