When is the best time?
Peak: 10 Sep – 20 Oct. Mid September to mid October
Active from 15 Aug to 15 Nov (August to November) in a typical year.
Time of day
First 3 hours after sunrise, best in onshore (north-westerly) winds
- Morning seawatch: sunrise → 3 h after sunrise
What will you hear?
A visual seawatch over the Cap Blanc upwelling — the same seabird river that Ngor (Dakar) and the Banc d'Arguin islands see; gannets and skuas within the surf line on windy mornings. Sound value is low unless you deploy a hydrophone for the fish-and-dolphin activity of the upwelling.
Binoculars?
Telescope recommended. Seabirds pass 200 m to 2 km off the cape in an onshore wind; a scope is the whole point, binoculars catch only the nearest.
Where to go
- Baie de l'Étoile — Sheltered bay 12 km north of Nouadhibou inside the peninsula: Atlantic humpback dolphin records and tern/flamingo roosts; a calm-water alternative when the Cap Blanc seawatch is blown out. Map
- Ras Nouadhibou lighthouse / Cap Blanc reserve — Watch from the cape; the reserve track is the access. Map
- Nouadhibou – Baie du Lévrier shore — Terns and gulls roosting; the ship graveyard is a noisy backdrop. Map
How to go on your own, and what it costs
Taxi from Nouadhibou to the Cap Blanc track; the lighthouse point is inside the small reserve (day fee) but the Baie du Lévrier shore is public and free.
Cost: Reserve entry small fee — check current prices; shore free.
Field-recording notes
Included for completeness on the flyway: a place to hear almost nothing but a 20-knot wind and surf. Little coverage — your counts are worth submitting to Trektellen/eBird.
