Wildlife in March in Watamu

The figures below describe a typical week on the water in March, not a promise for your Tuesday. Captains still confirm what the sea did that morning before you leave the beach.

Wildlife chances in March in Watamu Marine Park
Wildlife	Chance	What that means in March
Humpback whales (breaching)	0%	Humpbacks are still on the feeding grounds. Do not book March for whales.
Humpback whales (mothers & calves)	0%	No calving activity in Watamu in March.
Bottlenose dolphins	100%	Resident pods remain the everyday mammal story. Sightings stay high on settled mornings.
Whale sharks	80%	Still a strong month, slightly behind February. Reports taper as plankton patches break up.
Manta rays	70%	Good chance on cleaning stations while warm water holds.
Green sea turtles (nesting / hatching)	60%	Nesting declines from the December–February peak; occasional hatchings continue.
Mida Creek migratory birds	70%	Northbound waders start leaving Mida. Numbers are still worthwhile on a spring low tide.

Snorkeling and diving in March

Optimal reef snorkeling and diving conditions. Kaskazi typically flattens the surface and lifts water clarity toward 22 metres — pool-like visibility on settled mornings. This is the window for snorkeling the outer coral gardens and, when certified and conditions allow, diving sites such as Vuma Caves. Morning low-tide slots still give the sharpest views.

Still a clear-water month, typically 18–25 m, until late-March squalls start to put colour in the lagoon after heavy showers.

Ocean conditions in March

Kaskazi is ageing. Surface temperatures remain near 29°C and whale sharks are still in the area, but the Inter-Tropical Convergence Zone is sliding south. Short, heavy showers at month-end can dump sediment into the creek mouths and knock visibility for a day or two. Plan marine-park mornings early in the month if you can.

Which Watamu boat trips fit March

Wind, visibility and wildlife this month decide which trips make sense. The table maps the packages people actually book in Watamu onto those conditions.

Boat trip fit for March in Watamu
Trip	Fit this month	Why
Humpback whale safari	Not in season	Humpbacks have not arrived yet, or they have already left for Antarctic feeding grounds.
Whale shark watch	Peak reports	Plankton blooms pull whale sharks toward the surface. Captains track recent sightings before you leave the beach.
Glass-bottom coral gardens	Optional extra	Clear water favors snorkeling; glass-bottom boats remain useful for children and non-swimmers.
Deep sea fishing	Moderate	Calmer Kaskazi water is pleasant on a boat, but pelagic action is usually quieter than in the Kusi months.
Kitesurfing (Garoda)	Light / inconsistent	Kaskazi is warmer and flatter — better for swimming than for powered kites.
Mida Creek dhow cruise	Recommended	A creek dhow cruise is a calm contrast to the marine park, with birdlife on the mudflats at low tide.

What to pack for a March marine day

March packing is about the sea state above, not a generic beach list. Take what the month actually asks for.

Rash guard and a light rain shell for afternoon squalls
Reef shoes for wet landings if the beach is chopped after rain
Dry bag — March showers arrive fast
Sunscreen; UV is still fierce between clouds

Local captain’s note for March

If a night of rain turns the lagoon green, shift the day to Mida Creek or wait 24 hours. Captains know when the ebb has flushed the worst of the silt back out of the coral gardens.
