Is May Right for You?
Weigh the advantages and considerations before booking
Advantages
- + The first week of May is the tail-end of Palau's dry season, giving you the year's clearest water visibility for diving and snorkeling before the rains settle in
- + Hotel rates drop 25-30% from peak season prices starting mid-May, while marine life viewing remains excellent
- + Jellyfish Lake typically reopens in late May after seasonal closures, offering the surreal experience of swimming among millions of stingless jellyfish
- + Local fruit season peaks - you'll find the sweetest mangoes, papayas, and soursop at Koror's morning market, flavors that never make it to export
Considerations
- − Afternoon thunderstorms roll in like clockwork around 2pm, lasting 30-45 minutes and making boat schedules unpredictable for the second half of the month
- − The UV index hits 8 - without proper sun protection, you'll burn within 15 minutes on the water, even through cloud cover
- − Humidity at 70% means clothes never fully dry. Cotton stays damp and everything develops that unmistakable tropical mustiness within days
Best Activities in May
Top things to do during your visit
Rock Island Lagoon Kayaking Tours
May's morning glass-off conditions create mirror-calm water in Palau's famous lagoon before afternoon winds pick up. The limestone islands reflect well at 7am, and you'll have the hidden beaches to yourself before day-trippers arrive from Koror. Water temperature hovers at 29°C (84°F) - warm enough to jump in without hesitation.
Booking Tip: Book sunrise departures through licensed operators (see current options in booking section below). Morning tours typically run 6am-1pm to beat the afternoon storms.
German Channel Manta Ray Dives
May happens to be peak manta ray season at German Channel, where these giants come to cleaning stations in 12m (40ft) of crystal water. The incoming tide brings them in groups of 8-12, and the visibility - still 30m (100ft) in early May - makes for photography that looks like it was shot in an aquarium.
Booking Tip: Certified divers should book 2-3 days ahead through PADI operators. Bring a 3mm wetsuit - you'll spend 45 minutes stationary at cleaning stations.
Ngardmau Waterfall Jungle Treks
The 30-minute hike to Palau's tallest waterfall feels different in May - the trail stays muddy from intermittent rain. But the 250-foot cascade is at its most powerful. The pool at the base runs deep enough for swimming, and the surrounding jungle amplifies the roar to cathedral-level acoustics.
Booking Tip: Start early to avoid the steam-room effect on the trail. The 3km (1.9 mile) hike involves rope sections - wear shoes you don't mind ruining.
Milky Way Mud Bath Experiments
This natural limestone pool - Palau's famous 'spa' - works best in May's humid conditions when the white clay sticks to your skin long enough for the full treatment. Locals swear by the silica-rich mud for sunburn relief, and the surrounding rock formations create natural shade during the hottest part of the day.
Booking Tip: Most Rock Islands tours include a stop here. The mud works - leave it on 15 minutes before rinsing for the full effect.
Stone Monolith Cultural Tours
Badrulchau's ancient stone monoliths - some weighing 5 tons - sit exposed on Babeldaob's north coast. May's cloud cover makes midday visits bearable, and the recent paving of the access road means you won't destroy your rental car. These 100+ basalt pillars predate European contact, and local guides explain their connection to Palau's complex clan system.
Booking Tip: Hire guides through the booking section below - they'll explain which stones represent which clans, knowledge not in any guidebook.

May Events & Festivals
What's happening during your visit
Mid May
Palau Fishing Derby
Local fishermen compete in this weekend tournament targeting wahoo, tuna, and mahi-mahi. You'll see traditional outrigger canoes alongside modern sport fishing boats at the Koror dock, and the weigh-in becomes an impromptu fish market where visitors can buy the day's catch straight off the boats.
Late May
Liberation Day Commemoration
Palau marks its 1994 independence from US administration with parades and traditional dance performances at the National Capitol. The morning parade features every school and government office, while evening brings beach BBQs where families share reef fish and tapioca pudding.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The locals' secret: hit the Koror market at 6am when fishermen unload. You'll see species that never appear on restaurant menus, and prices drop by half after 7am when the hotels finish buying.
May's weather pattern is predictable enough to plan around - do water activities before noon, schedule indoor/cultural stuff for 2-4pm during storms, then back outside for sunset around 6pm.
Palau's famous fruit bat soup is a ceremonial dish - tourists requesting it at restaurants are unknowingly asking for something sacred. Skip it unless invited to a traditional feast.
The 'no sunscreen' rule at Jellyfish Lake isn't environmental overreach - the chemicals kill the jellyfish. The park rangers check bags, and they've seen every smuggling attempt.
Avoid These Mistakes
Booking afternoon boat tours in late May - storms make schedules unreliable after 1pm, and operators won't refund for weather cancellations
Assuming all beaches are public - many are traditional clan lands requiring permission or small access fees that support local families
Never wear new snorkeling gear untested. A leaking mask turns great destination into pain after 30 minutes. Outer islands sell zero replacements. Test the fit at home. Pack a spare.
