From SRD:
*********** spell Owl’s Wisdom
The transmuted creature becomes wiser. The spell grants a +4 enhancement bonus to Wisdom, adding the usual benefit to Wisdom-related skills. Clerics, druids, paladins, and rangers (and other Wisdom-based spellcasters) who receive owl’s wisdom do not gain any additional bonus spells for the increased Wisdom, but the save DCs for their spells increase.
************ class monk
AC Bonus (Ex): When unarmored and unencumbered, the monk adds her Wisdom bonus (if any) to her AC. In addition, a monk gains a +1 bonus to AC at 5th level. This bonus increases by 1 for every five monk levels thereafter (+2 at 10th, +3 at 15th, and +4 at 20th level).
These bonuses to AC apply even against touch attacks or when the monk is flat-footed. She loses these bonuses when she is immobilized or helpless, when she wears any armor, when she carries a shield, or when she carries a medium or heavy load.

So, if I cast "owl's wisdom" on a Monk - does his AC increase by 2 under most circumstances?
