Every year between July and September, the waters surrounding the Bazaruto Archipelago National Park begin to transform.
The ocean becomes louder. Surface activity increases. Blow sightings appear on the horizon. Breaching events become part of daily fieldwork.
This is Whale season Mozambique — one of the most active and dynamic marine monitoring periods in the Western Indian Ocean. At the BCSS Ocean Observatory, humpback whale activity becomes part of everyday research operations.
Every year, Humpback whales Bazaruto migrate through the region during one of the most important seasonal windows for marine mammal monitoring in Mozambique. For researchers, marine science students, divers, and conservation-focused travellers, it is a rare opportunity to move beyond observation and become part of an active research environment.
At BCSS, whale season is not built around tourism schedules or occasional encounters. It is integrated into long-term ocean monitoring, marine megafauna research, and ecosystem observation within Africa’s first permanent multi-ecosystem Ocean Observatory.
And every season, placements fill quickly.

What Whale Season Looks Like at BCSS
During whale season, humpback whales migrate through the waters surrounding the Bazaruto Archipelago, creating near-daily opportunities for observation and monitoring.
Field days may include:
- Breaching activity
- Tail slaps and surface behaviour
- Mother and calf observations
- Migration tracking
- Acoustic detections
- Behavioural logging
- Marine megafauna surveys
The intensity of activity during this period transforms the atmosphere of the station. Days are shaped around environmental conditions, sightings, field operations, and ongoing monitoring efforts.
Importantly, this is not a whale watching programme.
This is active fieldwork taking place within a professional marine science environment.
Participants joining BCSS during whale season contribute to long-term datasets supporting marine conservation and ecological understanding in the Western Indian Ocean.
Why BCSS Is Different
One of the defining aspects of BCSS whale season is the integration of science, conservation, and immersive ocean experience.
BCSS operates from a permanent research station on Benguerra Island, Mozambique, supporting:
- Long-term cetacean monitoring
- Oceanographic observation
- Marine biodiversity research
- Conservation-focused diving operations
- Scientific training and capacity building
The Ocean Observatory structure means whale monitoring is not isolated. Whale observations are integrated into broader environmental datasets that include:
- Ocean conditions
- Acoustic monitoring
- Biodiversity observations
- Marine megafauna records
- Long-term ecosystem trends
This makes BCSS one of the few places globally where participants can live inside an active whale research environment while contributing to real scientific work.

The STP Whale Season Placement
The Scientific Training Programme (STP) whale season placement is designed for individuals seeking direct field exposure within a professional marine science environment.
Participants are not passive observers.
They work alongside BCSS researchers supporting:
- Whale sighting documentation
- Behavioural observations
- Identification work
- Data entry and logging
- Marine megafauna monitoring
- Field preparation and operations
The programme functions as a hands-on Whale research programme Mozambique, combining marine science, field monitoring, and conservation exposure in one of the most biodiverse marine ecosystems in Africa.
For many participants, this becomes their first exposure to operational marine science outside of university environments.
The placement is particularly relevant for:
- Marine biology students
- Individuals seeking Marine biology internships Africa
- Conservation-focused gap year students
- Divers pursuing ocean careers
- Early-career researchers
- Individuals seeking meaningful Ocean conservation placements
Life on Benguerra Island
Beyond the research itself, the experience of living and working on Benguerra Island becomes a defining part of the programme.
Located within the Bazaruto Archipelago National Park, participants spend several weeks immersed in:
- A remote island environment
- Daily ocean exposure
- Small-team field operations
- Diving and marine monitoring
- Conservation-focused living
The station environment is intentionally collaborative and small-scale, creating close interaction between researchers, participants, dive staff, and visiting collaborators.
For many, the combination of scientific responsibility and direct connection to the marine environment becomes transformative.
This is not simply a programme.
It is a life experience built around ocean science, conservation, and immersion in one of the Western Indian Ocean’s most extraordinary ecosystems.
Limited Whale Season Placements Available
Current availability for 2026 whale season placements:
📍 1 July – 6 August
📍 29 August – 1 October
⚠️ September currently has only 2 spaces remaining
Because BCSS operates with intentionally small groups and active field integration, placements remain limited.
This ensures:
- Higher-quality mentorship
- Greater field exposure
- Meaningful scientific contribution
- Lower operational impact within the ecosystem
Demand during whale season is consistently high, particularly among participants seeking meaningful conservation and research experience rather than traditional tourism-based programmes.
More Than Whale Encounters
While humpback whales are the catalyst for the season, the broader significance of the programme lies in contribution and participation.
Whale season supports:
- Long-term migration datasets
- Marine mammal monitoring
- Ocean conservation research
- Ecosystem understanding
- Environmental awareness and education
Participants become part of a larger effort to better understand marine ecosystems within the Western Indian Ocean.
This is what makes the experience fundamentally different from simply observing wildlife.
It is participation in an active research system.
If you’ve been thinking about joining BCSS during whale season, now is the time.
