The following words are not me exagerating: It would litery kill an English person, since the english are used to a colder climate, it would be like putting a block of ice in a pan of boiling water.
Ok, so I am exagerating a bit, but, you understand what I mean.
Also, Spanish is an easy language to learn, but whatever you do, do not, I repeat, do not learn Spanish from English people, or learn in a resort mostly occupied by English, go to a very Spanish area (In-land Easten Málaga, for example) and that where you can learn to speak proper spanish, some for Portugease, or any languages, infact, just head in-land and learn it from a natural.
