Con Dao Islands in September
Not the best time
Still firmly in wet season territory. The brave few who visit find better deals but still face significant weather challenges.

September shows the first signs of monsoon weakening, but rain still dominates most days. Winds begin shifting, creating brief windows of calmer weather. Humidity starts a slow decline from peak levels.

All Months
November through April gives you the calmest seas and clearest skies. December and January are perfect — dry, breezy, and temperatures that hover around 26°C. The northeast monsoon from October through March brings choppy waters to north-facing beaches but makes the southern shores even more protected. Avoid May through September unless you're here for turtle season. The rains come hard and fast, flights get cancelled, and humidity makes everything stick to your skin. Vietnamese holidays like Tet in February turn the island into a domestic tourist magnet — book accommodations six months out or risk sleeping on the airport floor.
