in the worst possible way.
water is almost the only substance that makes honey go bad.
honey is hydroscopis-it bonds water from the air, that is why it didn't go bad in egypt, well it didn't go bad because egypt is hot and dry.
one way for perservation is crystalization, it stops the honey being hydroscopic.
anyway, if your water content rose above 18% there's a possibility your honey will ferment.
how much water into how much honey? if you can borrow the refracto-meter, borrow it and measue, if the ammount of honey is small enough, try to use it up ASAP, and keep an eye on it.
