Meteo Port Vila in maggio

Forum posters describe March as Vanuatu's rainiest month, hot, humid and steamy, though conditions are generally less severe than that label might suggest - rain most often arrives at night or during a stretch of the afternoon before clearing to a genuinely beautiful day, rather than washing out the whole visit. Posters are direct that March sits within cyclone season (October-April), though cyclones don't hit every island every year, and it's been several years since one directly struck Port Vila specifically. Posters describe a real upside to visiting during this less-touristed stretch: noticeably fewer visitors than the peak season. Posters generally rate March as hot, humid and genuinely rain-prone but rarely a washout for Port Vila, with real (if statistically modest) cyclone risk and lighter crowds as the trade-off.

Forum posters consistently describe September weather in Port Vila as just about perfect, particularly later in the month, with warm days, plenty of sunshine and noticeably cooler evenings around 20C - posters recommend packing a long-sleeved layer for after dark since the wind can turn chilly. Posters generally rate the water as warm enough for swimming and snorkeling by late September. Posters do flag real year-to-year variability, though: some visitors report spectacular weather throughout while others hit torrential downpours in the same month. Posters generally name the August-through-October stretch, September included, as one of the best overall windows to visit.
