Plan a swim, sort your gear, and give clear water-safety instructions — out loud.
First, the word for pool: in Mexico it's la alberca; most of the rest of Latin America and Spain say piscina — match your interlocutor and don't mix the two mid-conversation. The safety line worth knowing cold: si sientes que te jala la corriente, no luches contra ella, nada paralelo a la orilla — and a rip current is corriente de resaca, never a literal "corriente rota". One more that matters: drowning is pronominal — me estoy ahogando, not estoy ahogando (and definitely not estoy drogando, which means drugging).
Below: the phrases lesson by lesson — pool, open water, safety, gear — the Mexican pool-deck expressions locals actually use, and a way to rehearse the whole beach conversation out loud with a lifeguard who talks back.

Regional Spanish
Textbooks teach one word. Locals use several — pick your region's and stay consistent.

The part no phrase list can do
Isabella
Your conversation teacher for this pack
In the Dive Bomb pack, the final lesson is a Saturday morning at the lifeguard stand in Puerto Vallarta — and Isabella plays Marisol, a certified lifeguard and swim coach: warm, direct, a little jokey (órale, sale, ándale), and instantly serious the moment she spots real risk. Rescue boards and colored flags in view, she's finishing her coffee before the shift change and has fifteen minutes. You want to get into the sea and teach your nephew — who can barely swim — the basics, and she won't let either of you in the water until you show her you've understood the flags, the rip current, and what to do if someone gets in trouble. Out loud. And she talks back:
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.
Quick answers
Both mean swimming pool. Alberca is standard in Mexico and Central America; piscina everywhere else and in Spain. Pick the one your listener uses — mixing them in the same conversation marks you as a learner.
Corriente de resaca, or just resaca — not a literal "corriente rota", and don't confuse it with the other resaca (a hangover). The rule that saves lives: no luches contra ella, nada paralelo a la orilla.
¡Auxilio! — and get the professionals moving: llamen al salvavidas y avisen al 911 ahora mismo. If you're the one who spots trouble: si ves a alguien en apuros, grita pidiendo ayuda y llama al salvavidas — never go in alone.
¿Está picado el mar hoy o se puede entrar tranquilo? — is the sea rough or can we get in? Then check the flag: antes de meterte al mar, fíjate siempre en el color de la bandera; yellow means hay que tener cuidado.
Three things, by context: the lifeguard (pregúntale al salvavidas antes de entrar), the life jacket (chaleco salvavidas — póngase el chaleco salvavidas aunque sepan nadar), and a rescue float (flotador salvavidas).
