A diving snorkel assembly (10) including a snorkel tube (12) having an air inlet end (14) and a mouthpiece (16). The snorkel tube (12) defines a fluid passageway (18) extending between the end (14) of the tube (12) and the mouthpiece (16). An exhaust valve (24) is disposed between the mouthpiece (16) and the end (14) of the tube (12) for allowing one-way exhaust of fluid from the fluid passageway (18). An exhaust baffle (26) extends across the fluid passageway (18) adjacent to the exhaust valve (24) for establishing an exhaust fluid flow from the mouthpiece (16) through the fluid passageway (18) toward the exhaust valve (24) in response to air pressure from the mouthpiece (16).
