The best time to visit Alphonse Island is typically during the dry season, from April to November, for ideal weather conditions.
During these months, you'll experience consistently warm temperatures, generally ranging from 25°C to 29°C, with less humidity and a lower chance of rain. The sea conditions are usually calmer, making it superb for water activities such as snorkelling, diving, and paddleboarding. This period offers the clearest waters and best visibility for exploring the coral reefs and marine life.
Couples looking for a romantic escape will find this period particularly appealing. The pleasant weather allows for uninterrupted enjoyment of the island's pristine beaches, private dining experiences, and sunset cruises. The calm seas are ideal for leisurely swims and relaxing by the water without concern for rough conditions.
For those interested in fishing, particularly fly-fishing, the shoulder months within this dry season, such as April, May, October, and November, are often considered prime.
