New Caledonia in March

April through November brings New Caledonia's dry season — think 75-85°F days with low humidity and trade winds that keep mosquitoes at bay. This is prime time for diving, with 100-foot visibility common in the lagoon. But here's what the guidebooks don't mention: July and August see an influx of French tourists escaping winter back home, so book accommodations early and expect higher prices. May and September hit the sweet spot — perfect weather with fewer crowds and better deals on hotels. The wet season from December to March isn't necessarily a write-off. Sure, you'll get afternoon thunderstorms and higher humidity, but the rainforest comes alive, waterfalls run full, and hotel rates drop by 30-40%. Cyclone season technically runs November through April, though direct hits are rare. Water temperatures stay warm year-round (75-82°F), so you can dive comfortably in just a 3mm wetsuit even in winter.
