When is the best time to visit Mozambique for Bazaruto Archipelago?

The Foreign, Commonwealth and Development Office states plainly that Mozambique's rainy season runs from November to April and that cyclones and floods are common in that period. It adds the practical consequence: low-lying ground near the major rivers floods regularly and at short notice, roads become impassable — including in Maputo — and landslides close transport links. For an archipelago reached by a mainland flight or a boat transfer from Vilankulo, those are not background conditions; they are the difference between arriving and not arriving.

Bazaruto itself is a formally protected area with a documented legal history. The park was proclaimed on 25 May 1971 by Legislative Diploma No. 46, covering 600 square kilometers, and its limits were revised by Decree No. 39/2001 of 27 November 2001 to the present 1,430 square kilometers, roughly 552 square miles. That extension is why the park now covers open water and seagrass beds between the islands rather than just the island shores, and it is the reason its headline species is a marine mammal: the Marine Conservation Institute's protected-area record puts more than 250 dugongs here, the largest population on the western side of the Indian Ocean.

The security picture, usefully, points away from the archipelago rather than at it. The US Department of State rates Mozambique Level 2, "Exercise increased caution when traveling to Mozambique due to health issues, crime, civil unrest, and terrorism," having lowered it from Level 3. Its Level 4 Do Not Travel designations apply to Cabo Delgado Province, the Niassa Special Reserve in Niassa Province and certain northern Nampula districts — all of them far north of Inhambane Province, where Bazaruto lies.

These are not coral islands but tall vegetated sand dunes sitting on a shallow bank, with freshwater lakes held in the hollows behind the ridges — which is why the park's bird list runs past 180 species on islands that look, from the water, like nothing but sand.

The 2001 boundary revision matters to how you behave once you are there. Because the park is a marine protected area more than an island group, the regulated space is the water column and the seagrass between the islands, not just the beaches. Dugongs feed on those seagrass beds, and four of the five sea turtle species recorded in the park breed on its beaches — so boat routing and beach access are managed, and a self-directed snorkeling plan is not how the park works.

• May to October — Travel in the dry half of the year, outside the FCDO's stated November-to-April cyclone and flood window.
• On the water — Expect boat movements and dive sites to be set by park rules inside a 1,430-square-kilometer protected area.
• North stays off the list — Keep Cabo Delgado, the Niassa Special Reserve and the named northern Nampula districts out of the same trip; all carry Level 4 designations.

Even in the dry season, access is the weak link: Bazaruto is reached through Vilankulo, and the FCDO notes that flooding and landslides disrupt Mozambican roads at short notice. Under US guidance the passport needs six months of validity beyond arrival and two genuinely blank visa pages — endorsement pages are not counted. A yellow fever certificate is required of travelers arriving from a country where yellow fever is present, and anyone who cannot produce one at the port of entry is vaccinated there at their own expense. The advisory's own headline lists health issues first, which is a fair summary of the risk profile on a tropical coast.

The Mozambique trip-planning question in this chapter handles the visa and passport sequence in detail, and the places question covers the Island of Mozambique and the protected areas further north.
