Is September Right for You?
Weigh the advantages and considerations before booking
Advantages
- + September kicks off the cashew harvest. Roadside stalls from Bissau to Bafatá roast the new crop over open fires, sending caramel-smoke drifting through the thick, humid air.
- + Once August's rush ends, hotel rates fall 30, 40%; beachfront rooms in Varela that were booked solid in July suddenly accept walk-ins.
- + The season's last downpours leave the rice paddies around Bissorã an almost unreal green under afternoon sun, good for photos the moment storms pass.
- + Evenings cool to 24°C (75°F), so locals reclaim the outdoor markets; Quinhamel's Saturday fish market under string lights fills the whole village after 7 PM.
Considerations
- − September still delivers 14 inches (360 mm) of rain, sudden afternoon storms can turn Bissau's sandy streets into red rivers within minutes.
- − Humidity sticks near 70% and feels heavier. Cotton clothes never quite dry, and the salt breeze off Bubaque Island leaves metal door handles tacky.
- − Heavy rain can make dirt roads to villages like Cacheu impassable for days, scuttling day trips to the old trading posts.
Best Activities in September
Top things to do during your visit
Bissagos Islands boat expeditions
By month's end, storms exhaust themselves on the mainland, leaving the channels between islands glass-calm. Dolphins trail your pirogue from Orango to Rubane, and with mainland squalls blocked by distance, September becomes the cheapest, quietest window for multi-day island hops.
Booking Tip: Book 5, 7 days ahead through licensed operators at Bissau port, choose boats with shade canopies and life jackets for the 4, 6 hour crossings.
Bissau-Guinean food tours
Evenings settle at 26°C (79°F), good for wandering Bandim Market's palm-oil stew stalls. Post-harvest vendors sell fresh palm wine and hot cashews, while the daily rinse of rain keeps outdoor tables cooler than any other month.
Booking Tip: Guides gather at Hotel Malaika reception at 6 PM nightly, no reservation required. Just turn up hungry and in shoes you don't mind trashing.
Cacheu historical cycling routes
Cacheu's crumbling Portuguese fort and baobab-lined lanes ride best after 4 PM, when the day's rain has cooled the air to 25°C (77°F) and firmed the laterite roads just enough for two wheels.
Booking Tip: Basic mountain bikes wait at Cacheu port, allow 3, 4 hours to pedal to the slave museum and riverside fish-smoking sheds on sandy tracks.
Varela Beach kayaking tours
Post-storm swells groom the year's cleanest runs for sea kayaking through the mangrove channels where salt and fresh water mingle. Warm rain and tropical sun often trade places within the same hour.
Booking Tip: Leave Varela Beach between 7, 9 AM; local fishermen supply kayaks and know the shifting tide tables that keep you off sandbars.
Cantanhez Forest chimpanzee tracking
Forest fruit draws chimpanzees lower in September, so the 2, 3 hour morning hikes offer better sightings. The 5 km (3.1 mile) trail through primary rainforest stays cushioned by recent rain.
Booking Tip: Licensed guides are mandatory, sign up at park headquarters in Catio village and wear long sleeves against thorny vines that stay wet until 11 AM.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
Score the freshest palm wine at Bubaque Island roadside stands on Wednesday mornings, when new batches arrive from mainland distillers.
Bissau's Saturday market fires up Friday at 6 PM, vendors slash prices before weekend rains, and locals beat the crowds.
Bring coins for the Bubaque ferry, the ticket booth never has change, and fellow passengers will swap 500 CFA notes at lousy rates.
Download offline maps before arrival, September storms regularly topple mobile data towers, on the islands.
Avoid These Mistakes
Skip beachfront rooms that rely on grid power only. When storms kill the line, fan-less rooms turn into ovens within hours.
Don't bank on Bubaque's ATM, load up with cash for 3, 4 days; the single machine is often empty.
Leave the jeans at home, humidity turns denim into a pair of wet towels after half an hour outside.
