Is May Right for You?
Weigh the advantages and considerations before booking
Advantages
- + May is your final dry window before the June monsoons. Dirt tracks to the Bijagós islands and the Casamance border stay open to normal cars. That door slams shut by mid-June. Plan now.
- + Coastal mangroves near Cacheu and Orango Islands National Park glow emerald. Water clarity for pirogue trips through saltwater channels is surprisingly good. You see the archipelago's complex ecology before rains turn everything brown.
- + Hotel rates and flight availability tilt in your favor. You slide between dry-season expats and the rainy slowdown. Europeans have not yet flooded the system.
- + Evenings cool just enough. Sit streetside in Bissau Velho with a chilled Super Bock. Morna drifts from a radio. The Atlantic rustles cashew trees overhead.
Considerations
- − Variable means brutal. Morning heat shimmers like a sponge. A violent squall turns sandy streets into rivers for twenty minutes. Sun returns, blinding. Rigid plans fail here.
- − Humidity hovers at 70%. A walk through Mercado de Bandim becomes a full-body event. Dried fish, ripe mangoes, diesel exhaust cling to skin.
- − The Bijagós archipelago is still reachable. Yet the sea builds a swell. The two-hour pirogue hop from Bissau to Bubaque Island can turn choppy. Not for fragile stomachs.
Best Activities in May
Top things to do during your visit
Bijagós Archipelago Island-Hopping
May is your final clear shot at the islands before the rains make crossings dicey. The sea stays mostly calm, sandflies are fewer, and island-hopping from Bubaque to Rubane to Orango is straightforward. Lodges remain open but uncrowded. Water temperature invites long wades, and empty stretches like Bruce Beach on Bubaque feel private. Expect bouncy pirogue transfers, bags wrapped in plastic, salt spray on your face.
Booking Tip: Arrange everything through local operators in Bissau. Online last-minute booking does not exist. Budget two full days in the capital to secure boat tickets and park permits. The widget below shows current day-trip options, yet multi-day island stays are fixed on the ground.
Bissau Velho Historical Walking Tours
Explore the capital's crumbling Portuguese colonial core in the gentle light of early morning or late afternoon. Pastel walls of the old Presidential Palace and Fortaleza de São José da Amura glow. Shutters squeak, guava scents the air, azulejo tiles flake under fingers. Guides often share family stories. No plaque can match that.
Booking Tip: Seek licensed guides linked to the Instituto Nacional de Estudos e Pesquisa (INEP). They turn ruins into living narrative. A half-day tour is plenty. Book a day or two ahead through your hotel or a downtown office.
Cacheu River Mangrove Exploration
The Cacheu River mangroves, a protected biosphere, drip green in May. Pre-rain humidity sharpens leaf color and the smell of tidal mud. A local guide poles the pirogue through overhung tunnels where egrets lift, monkeys shake branches, and a saltwater hippo might surface. Silence returns when the motor cuts.
Booking Tip: Community outfits in Cacheu town run the trips. Drive three hours from Bissau and negotiate on the spot. The experience is raw, unfiltered. Some Bissau operators sell day trips. Check the booking section for current slots.
Local Market & Street Food Exploration
May harvest piles the stalls high. Mercado de Bandim erupts with scarlet chilies, sweet cashew fruits, and the smoky perfume of grilled chicken piri-piri. Try caldo de mancarra, a peanut stew locals trust against the shifting weather. Bring a guide who knows the maze.
Booking Tip: Skip formal food tours. Ask your concierge or guide for their favorite stall. Lunch costs pennies and tastes honest. No booking, just appetite and sanitizer.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
Repeat 'Cedo é melhor' at dawn. Leave for islands or interior first light. Heat stays low. Photo light glows. You beat afternoon storms.
Cards work in maybe two Bissau hotels. Economy runs on West African CFA francs cash. Many tourist spots take euros but rate is worse. Change small amount at airport. Use banks in Bissau city center for better rate.
Hire car and driver for the vehicle, not per head. Toyota Land Cruiser day-trip to Cacheu costs same for one or four. Split with travelers met at hotel.
Sudden afternoon headache or lethargy signals dehydration, not illness. Humidity masks thirst. Drink water constantly. Buy rehydration salts cheaply at local pharmacies.
Avoid These Mistakes
Packing only for beach weather fails. May brings equatorial pre-monsoon sun, rain, humidity, muddy paths all in one day. Bring layers.
Do not wing island travel. Boat schedules to Bijagós depend on tide, weather, passenger count. Arriving at Bissau port without plan can strand you 2-3 days.
Ignore Google Maps. 100 km can take four hours on sand roads, past checkpoints, pushing vehicles from mudholes. Patience is mandatory.
