You can indeed change the language at Special:Contact.

However, if your wiki is very new, it may be beneficial to instead leave the wiki and start a new one. This is because if you accidentally start an English wiki (meaning to start a Spanish wiki), you will be given English templates and the like - whereas if you started it in Spanish, they'll all be proper Spanish templates.

Switching the language of a wiki will not correct these templates, so it may be better to just start anew. Think for yourself if this is worth the amount of effort it'd take to move any content you've created (and know that you can move anything.)
