Well, I don't know exactly, but a few possibilities:
In what season do you swim? (Testing knowledge of seasons, perhaps?)
In what station (in this case, place, 'lugar') do you swim?
Perhaps this helps.
in what station is it.
It means, "What season is December in?"
In what season is it very cold?
Que te gusto hacer en junio y en diciembre
en que consisten las actividades secundarias
in what station is it.
As a translation: What season are we in? As an answer: Estamos en la primavera.
It means, "What season is December in?"
In what season is it very cold?
In what season/part of the year is (your) birthday
¿En que estacion hace frio? means: In what season is it cold?
In what season do you like to swim?
what station are we on during the forecast
The translation of "en que estacion esta el mes" from Spanish to English is "in what season is the month."
This means "On what station is your birthday?" in Spanish. It seems there might be a typo or mistranslation in the phrase "de tu compleanos," as it should be "¿En qué estación es tu cumpleaños?" to inquire about the date or time of someone's birthday.
Tu nadas EN la pisCina = you swim in the fishpond/swimming-pool
La primavera comienza el 21 de marzo.
