Marea translates to "tide" and is a beautiful, evocative word that isn't as common in everyday song lyrics as more direct emotional terms.
In the song, the lyric "subió la marea" (the tide rose) is used metaphorically to describe the surge of emotion the singer feels upon seeing someone. It paints a vivid picture of being overwhelmed by feelings, much like a rising tide, making it a memorable and poetic choice.
This song is built entirely around one moment: catching someone's eye and being too nervous to say anything. It opens on a train, "En el calor del tren, un día cualquiera" [In the heat of the train, on any given day], and then someone sits down close by and the whole song shifts gears, "Cuando te vi entrar, subió la marea" [When I saw you come in, the tide rose]. Surfistas Del Sistema keep the setting small on purpose. It's just two people on a commute, both aware of each other, neither one saying a word.
The title is the whole idea in one line, "Te miro, para ver si me ves mirarte" [I watch you, to see if you catch me watching you]. Since the narrator can't say anything out loud, he writes it down instead, "Te escribo lo que no te pude hablar" [I write you what I couldn't say to you], then just goes home hoping to dream about them, "Me duermo para, al menos, poder soñarte" [I fall asleep so I can at least dream of you]. By the last chorus the band drops the subtlety completely and just shouts "Más, más, más, más" [More, more, more, more], which says everything the shy glances couldn't.
