June and July sit inside Zanzibar's Kusi season — the south-east monsoon that brings the island's driest, coolest, breeziest months. Expect daytime temperatures in the mid-to-high 20s°C, low humidity, and a steady wind that keeps the heat honest, plus the busiest stretch of the year at Boutique Hotel Matlai. It's a genuinely good time to visit the east coast; it's also worth knowing what "breezy" and "busy" actually mean before you book.
What is the Kusi season, and why does it matter for June and July?
Kusi is the south-east trade wind that blows across Zanzibar roughly from May through October, and June and July are squarely in the middle of it. It's the opposite of the Kaskazi north-east monsoon that runs November through March — Kusi means dry, cooler, and consistently breezy; Kaskazi means warmer, more humid, and prone to short afternoon showers.
The practical effect at Michamvi Pingwe, on the island's exposed east coast, is a coast that stays comfortable outdoors from morning until night, with the wind picking up through the day rather than the still, heavy air of the wet season.
What's the actual weather like?
Daytime highs run roughly 25–28°C, nights cool to around 20°C, and the sea itself stays a swimmable 25–28°C year-round — Kusi doesn't make the ocean colder, just the air more comfortable to be in. Rain is genuinely rare in June and July; when it does show up, it's a brief shower rather than the daily downpours of the April–May long rains. Humidity is the lowest it gets all year, which is also why these months produce some of the clearest skies and sharpest light for photography.
The trade-off is wind. The south-east breeze that keeps the heat down also builds swells on this exposed stretch of coast, more noticeably in June and July than in the calmer, warmer months of January and February. It's rarely a problem for swimming — the beach at Matlai has a semi-diurnal tidal cycle, so there's a comfortable window around high tide most days — but it does mean the sea has more texture than the glassy conditions some other months offer, and it's exactly why this stretch of coast is popular with kitesurfers heading a little further south to Paje.
Is June or July better for diving and snorkelling?
Both work well, and neither is a clear winner over the other — visibility across the Kusi season generally runs strong from May into October, with mornings the more reliable window before afternoon wind stirs the surface. Blue Lagoon and Starfish Beach, the two snorkelling spots Matlai's butlers arrange boats to, are both doable in June and July; expect a touch more chop on the crossing than you'd get in the calmer shoulder months, without it affecting what you see once you're in the water.
If a fishing trip is on your list, June through September tends to favour reef species over the big pelagics — marlin, tuna and the larger game fish that Beach Bums Fishing Charters run out of run stronger from October through March. Neither season is empty-handed; it's a question of what you're fishing for.
Why are these the busiest months at Matlai?
June through September is peak season across Zanzibar's east coast, and July and August in particular line up with the northern-hemisphere summer break — school holidays, longer stays, more couples and families booking the full window. With only six rooms across Villa Kidosho and Asili House, Matlai fills up for these dates well in advance; three to six months ahead is a realistic booking window if you have specific dates in mind, longer still if you want a particular room. June itself is a shade quieter than July and August — the shoulder edge of peak season, with the same weather and a little more breathing room.
What should you pack and expect day to day?
Light layers cover most of it: the days are warm enough for swimwear and linen, but evenings with the wind up can call for a light layer at dinner, especially if you're eating at Zatiny's beachfront tables. Sun protection matters more than the mild temperatures suggest — the low humidity and clear skies mean UV exposure is strong even when it doesn't feel scorching. A hat and reef-safe sunscreen are worth packing rather than sourcing locally.
Because this is the sunrise coast — Michamvi Pingwe faces east, so the ocean views from the villas and pools are a morning event, not a sunset one — June and July's clear mornings are genuinely one of the highlights of visiting now. For sunset, your butler can arrange a ngalawa (the local wooden outrigger canoe — not a "dhow," which is a different, larger vessel) sail across to Chwaka Bay, where the view faces west.
Is it worth visiting Zanzibar in June and July with a Tanzania safari?
Yes, and it's a natural pairing: June through October is also the classic dry-season safari window on the mainland, when animals concentrate around water sources and game viewing is at its most reliable. The flight from Zanzibar to Arusha or Kilimanjaro takes about 45 minutes on a jet, longer on the smaller propeller aircraft common on this route — worth checking which you're booked on before you plan connections tightly.
Frequently asked questions
Is June a good month to visit Zanzibar? Yes — it's the start of the Kusi dry season: low rainfall, comfortable temperatures, and a steady breeze. It's also the quieter edge of peak season compared with July and August, so it suits guests who want the good weather without the fullest crowds.
Does it rain in Zanzibar in June and July? Rarely. Occasional brief showers can happen, but June and July are among the driest months of the year on the island.
What winds should I expect in June and July? The Kusi south-east monsoon — consistent, cooling, and a little stronger than the calmer January–February window. It's not the Kaskazi north-east monsoon, which runs November through March.
Do I need to book Matlai far ahead for these months? Yes — June through September is peak season, and July–August especially fills up. With six rooms across two villas, three to six months' notice gives you the best chance at your preferred dates and room.
