The available whale watch expeditions at Granite State Whale Watch are weekends at 11 am from May 12 to June 10; 2 pm from June 11 to June 15; 8:30 am and 2 pm from June 16 to August 26; weekends at 8:30 am and 2 pm and Monday through Friday at 11 am from August 27 to September 2; and weekends at 11 am and Monday, Wednesday and Friday at 10 am from September 3 to October 7.

Granite State Whale Watch has a 99% sighting record, so the odds are definitely in your favor, but unfortunately there's no guarantee to see a whale during your whale watch. Your whale watch boarding pass is chance to observe, rather than an admission to a show. It's up to the whales whether or not you get to see them. It's definitely worth trying to see if you can catch a sighting.
