Scuba Diving in Sesimbra
The waters in Sesimbra are crystal clear but a bit chilly, if you are used to Caribbean Waters. You will need a 5 mm suit to protect you. Water temperature is the same year round. In the summer you will be very hot, getting into the suit :) but always rewarded by ample fish life!
A reputable dive school is Nautilus Sub. They have tours and rent equipment! You can also call them at +351 96 400 81 39.
Anthia Diving Center leads deep water dives in Sesimbra waters. Their website has some great pictures!
Then we have Sesimbra's Dive Center, located at the Clube Naval Sesimbra. They are one, if not the oldest school in Portugal.
