Is May Right for You?
Weigh the advantages and considerations before booking
- + May lands cleanly between April's heavy rains and the June-July increase, gifting you deserted stretches like Praia Jalé where the only soundtrack is palm fronds brushing overhead while the sea holds steady at 28°C (82°F).
- + Humpback whale migration peaks now, watch them hurl themselves skyward off Ilhéu das Rolas from fishing boats that push off at dawn, the air thick with salt spray and the diesel rasp of old Yamaha engines.
- + Room rates at the older roças like Roça Sundy fall 30-40% from Easter highs. Yet the bougainvillea keeps spilling purple across the plantation buildings.
- + Afternoon rains arrive like clockwork at 3 PM, last 20-30 minutes, drop the temperature, and leave behind the petrichor locals link to the end of coffee harvest season.
- − Humidity climbs to 70% by 10 AM and stays there until sunset, your cotton shirts glue themselves to your back while you hike toward the 663 m (2,175 ft) base of Pico Cão Grande.
- − A handful of smaller guesthouses on Príncipe shutter for annual maintenance right after Easter, cutting accommodation choices in spots like Santo António.
- − River crossings en route to Lagoa Azul can balloon after morning rains, turning the 4WD track into a no-go zone until late afternoon when everything drains to the Atlantic.
Best Activities in May
Top things to do during your visit
May is prime time, humpbacks breach within 100 m (330 ft) of boats, mothers coaching calves in tail slaps. After 8 AM the sea lies glass-calm before the trade winds stir. Captain João has run these trips since 1987 and reads whale behavior better than many marine biologists.
May's on-and-off rain keeps the 4 km (2.5 mile) trail muddy yet passable, you'll catch the scent of wild ginger and hear African grey parrots scolding from 30 m (98 ft) up in the canopy. The 40 m (131 ft) waterfall runs strongest this month, forming the mist-cooled pool locals nickname 'banho de rainha'.
The old plantation houses at Roçan Agostinho Neto and Roça Água Izé clear out after Easter, handing you unobstructed shots of crumbling colonial walls wrapped in bougainvillea. Coffee-drying terraces still reek of fermentation under May heat, and you may spot elders roasting beans over open fires the way they've done since 1855.
From Praia Piscina's natural lava pool to the 7 km (4.3 mile) sweep of Praia Jalé, you'll own entire stretches. Water sits at 28°C (82°F) and visibility reaches 20 m (66 ft) offshore, good for drifting weightless with only the sound of your own breathing through a snorkel.
May evenings invite wandering the Mercado Central at 6 PM when the day's heat snaps and vendors fire up espada fish over coconut-husk coals. The market reeks of sea salt, diesel from idling boat engines, and the sweet smoke of calulu stew simmering in clay pots.
