Warm salt air, the engine’s low thrum and the Pacific unfolding blue beyond the bow — this is a typical morning launching for a two-tank dive out of Playa Flamingo and Tamarindo. Divers step off well-provisioned boats into water that alternates between glassy turquoise and a deeper indigo, the sea daring you to look deeper.

Book morning boats for calmer seas
Early departures often have gentler winds and better visibility; afternoon sea breezes can pick up quickly.
Bring a shorty wetsuit
Water temperatures and sun exposure between dives make a 3mm suit or shorty a comfort essential even in warm months.
Use reef-safe sunscreen
Apply biodegradable, reef-safe sunscreen before boarding to protect coral and comply with local conservation practices.
Manage ear clearing on repeat dives
Do slow equalization between descents—multiple dives increase ear pressure risk; stop if you feel pain and inform your dive leader.
Mask & snorkel
A well-fitting mask improves underwater visibility and comfort during surface intervals.
