March continues the drier pattern with clear days and good marine visibility, making it well suited for diving and boat tours. Crowds are moderate compared with peak winter holidays.

Main Hub
Late-morning humidity rises in March and the heat becomes more noticeable in Airai; thermometers commonly read around 29-30°C. Water visibility on day dives often remains very good before the wetter months set in, and ferries keep a regular schedule. For city-side visitors, shade is your friend-light clothing, a hat and an umbrella will keep you comfortable during sudden tropical showers.
Interior & North
March brings warmer afternoons in the interior and the rainforest begins to feel heavier and stickier; short heavy showers can appear suddenly but often clear within an hour. Rivers behind the hills slowly swell compared with the dry months, so waterfall flows start to pick up-this is an attractive time for visiting falls before the full monsoon arrives. Wear closed shoes for trails that start to show mud patches after sudden rains.
Diving, Kayaking & Snorkeling
March is pleasantly warm and the lagoon often holds steady visibility, making snorkeling at sites like Ngeruktabel a joy before the deeper wet season begins. Jellyfish Lake remains an iconic spot-check current access rules locally as conservation measures change-but many interior lagoons are perfect for midday glass-bottom observation. Pack waterproof reef shoes for rocky entry points and expect the odd short shower.
Southern Historic Islands
March warms noticeably and humid afternoons can make inland walks feel more exerting; if you plan to explore WWII trails, start early in the day to avoid the heat. Dive visibility on wrecks often remains good in the mornings, but expect rising humidity and occasional short rains by late afternoon. Carry water and sun protection on walks through sun-exposed battle sites where shade is limited.
Kayangel, Ngarchelong
March finds the atolls warming and slightly more humid; reefs offer excellent snorkeling before the wetter months begin to affect water clarity. Local captains recommend morning departures to avoid an afternoon swell, and day trips often include extended stops on sandbars and reef edges. Bring reef shoes and bottled water-expect long daylight hours exploring sparse infrastructure.
There are no major festivals or events in Palau during March to be aware of.
