It's also a matter of what you want out of it. The temps of your water bath on on the low end or below the preferred range of all the ale yeasts I'm aware of. That's not necessarily bad, but you will get a different beer that if you fermented in the high 60s or low 70s. Check the specs on the yeast strains you are considering. Nearly all of them are fairly accurate descriptions of what you can expect and what temperatures are preferred. Of course, they are all fairly vague and subjective (e.g., "makes a rounder, fruitier beer"), but they are accurate to that extent.
Keep in mind that, typically, lower temperatures lead to crisper, cleaner beers and that higher temperatures lead to rounder, fruitier beers. However, get outside a yeast's preferred range and bad things may happen. For example, temperatures that are too low may lead to a stuck fermentation or too much diacetyl left in the beer because yeasts don't metabolize it before you rack. Temperatures that are too high may lead to fusels, undesireable acetaldehydes, phenols, or overpowering esters that you did not care for.
