If you have a place that is consistently in the 60 to 62 range that should be ok. Just wrap a blanket around the carboy or something to keep it insulated. Once the Fermentation takes of it will heat up a bit anyway and should raise the temp. Otherwise you can go with a heater of some kind but it won't take much.
What you also want is consistency in your temps if possible.
