Is May Right for You?

Advantages

Rainy season hasn't peaked yet - expect only 10 rainy days with short afternoon showers lasting 20-30 minutes, leaving mornings and evenings clear for outdoor activities
Tourist crowds are 40% lower than peak December-February season, meaning shorter queues at Pico de São Tomé viewpoints and better photo opportunities without crowds
Sea visibility for diving reaches 20-25 m (65-82 ft) around Saotomeandprincipe - the best underwater visibility of the year before heavy rains reduce clarity
Cacao harvest season begins, allowing visitors to participate in actual farm work at roças (plantations) and taste the freshest chocolate directly from pods

Considerations

Afternoon humidity reaches uncomfortable levels between 2-4pm (feels like 38°C/100°F), making midday hiking challenging without proper preparation
Some dirt roads to remote beaches become muddy and impassable after rain - 4WD vehicles essential for exploring southern São Tomé's coast
Ferry schedules to Príncipe can be disrupted 2-3 times per month due to rough seas, potentially extending your island stay unexpectedly

Essential Tips

What to Pack

Quick-dry hiking pants and long sleeves for 70% humidity conditions - cotton retains moisture and becomes uncomfortable during 6-8 hour mountain treks

Waterproof hiking boots rated for muddy terrain - plantation visits and forest trails become slippery after 20-minute afternoon showers

SPF 50+ reef-safe sunscreen for UV index 8 conditions - regular reapplication essential during boat trips and beach activities

Lightweight rain jacket with ventilation zippers - afternoon storms are brief but intense, and you'll overheat in non-breathable materials

Insect repellent with 20% DEET minimum - forest mosquitoes are most active during May's humid evenings around plantation areas

Headlamp with extra batteries for 4am mountain hiking starts and early morning fishing expeditions with local communities

Dry bags in multiple sizes for protecting electronics during boat trips and keeping spare clothes dry in humid conditions

Lightweight merino wool socks that dry quickly and prevent blisters during long hiking days on varied terrain

Portable water purification tablets - remote plantation areas may have limited access to bottled water during extended visits

Cash in small denominations (dobra) - rural communities and local guides prefer cash payments, and ATMs are scarce outside São Tomé city

Insider Knowledge

Book domestic flights to Príncipe for Tuesday or Wednesday departures - weekend flights get cancelled more frequently due to weather, and Monday flights are often overbooked with government workers

Hire guides through the official Tourism Association office in São Tomé city rather than street approaches - certified guides cost 20% more but carry insurance and emergency communication equipment essential for remote areas

Visit local markets between 6-8am for the freshest produce and seafood - vendors sell out quickly, and afternoon heat makes market visits uncomfortable in 70% humidity

Negotiate multi-day packages with taxi drivers for island exploration - daily rates of ฿3,500-4,500 are cheaper than individual trips, and drivers know which remote roads are passable after recent rains

Avoid These Mistakes

Attempting Pico de São Tomé hikes after 7am start times - afternoon cloud cover and rain make summit attempts dangerous and reduce visibility to zero above 1,500 m (4,921 ft)

Booking accommodations only in São Tomé city - staying overnight near Príncipe airport or mountain communities provides access to sunrise activities and reduces daily travel time by 2-3 hours

Expecting reliable internet connectivity for work - even hotels advertise WiFi but connections fail frequently during afternoon rains, making remote work nearly impossible
