A quick search in Yahoo gives up these varied results:
http://www.deepdiscoveries.com/bayislands.htm says "March-June & Sept-Nov."
http://www.sfreefdivers.org/august2001.pdf says "spring & fall"
http://www.utila.com/dive.html says "year-round"
http://www.changeofscene.com/scuba/honduras.htm says "May thru Sept."
Before I went there, I saw all kinds of conflicting information too. As best as I could tell, they were around all year but you only had a 50% chance of seeing them if you were there for a week. After getting there and talking to the dive masters, I figured my estimate was right - but only on average! If you are there in February, you have an 90% chance. If you are there in June, you have a 10% chance. I learned my lesson and stopped listening to marketing hype. Now, when I plan a trip, I try to talk with divers who have experience at the site.
I hope this helps. One way or another, I hope you get to see them.
