Is May Right for You?

Advantages

Essential Tips

What to Pack

Quick-dry hiking pants - 70% humidity makes cotton uncomfortable, synthetic materials dry 3x faster after rain exposure

Reef-safe mineral sunscreen SPF 50+ - UV index reaches 8 and Palau strictly enforces coral protection laws with $1000 fines

Lightweight rain jacket with pit zips - afternoon storms last 45-90 minutes with 28°C (82°F) temperatures requiring breathable protection

Waterproof phone case rated IPX8 - essential for kayaking and sudden downpours, local replacements cost 3x US prices

Merino wool base layers - naturally antimicrobial for multi-day wear in humid conditions, cotton breeds bacteria rapidly

Diving booties or water shoes - mandatory for Palau and rocky shore entries, hotel pools require foot protection

Insect repellent with 30% DEET - mosquito activity peaks at dawn/dusk, dengue prevention requires consistent application

Dry bags in multiple sizes - 15L for day trips, 5L for phone/wallet, essential for boat tours and kayaking activities

Wide-brim hat with chin strap - afternoon winds on boats reach 25km/h (15mph), sun exposure intense on water

Probiotics supplements - dietary changes plus humid climate stress digestive systems, local pharmacies have limited options

Insider Knowledge

Book diving and snorkeling tours for 7am-11am slots - afternoon storms make 2pm+ tours frequently cancelled, morning departures have 95% completion rate

Purchase Palau permits online before arrival - saves 2+ hours in Palau queues and guarantees access during busy weekends when daily limits reached

Rent gear in Palau rather than bringing - 90% humidity causes personal equipment to retain moisture and develop mold within 48 hours

Stay hydrated with coconut water from local vendors - isotonic properties better than sports drinks in 70% humidity, costs $2-3 vs $8+ for imported alternatives

Avoid These Mistakes

Scheduling outdoor activities after 1pm - 60% chance of afternoon storms means missed tours and no refunds for weather cancellations

Bringing cotton clothing for multi-day activities - retains moisture in 70% humidity leading to chafing and odor, synthetic materials essential

Underestimating sun exposure on water - reflected UV from ocean surfaces doubles radiation exposure, many visitors suffer severe burns despite cloudy conditions
