Basking sharks frequent the Bay of Fundy from May to November, although your best chance of spotting one is in August and September. Despite being common in these months, there are some areas of the Bay where you are far more likely to see a basking shark than others. What makes good basking shark habitat??
Zach Siders, currently a doctoral student at the University of Florida, did his Master’s research (at the University of North Carolina Wilmington) on the habitat use and diving behaviour of basking sharks in the Bay of Fundy and spent several summers conducting his research out of the Grand Manan Whale & Seabird Research Station. He recently published a paper on the habitat use of basking sharks in the Bay of Fundy entitled “Seasonal Variation in the Spatial Distribution of Basking Sharks (Cetorhinus maximus) in the Lower Bay of Fundy, Canada” in the scientific journal PLOS ONE. Zach found that from July to September, basking sharks are more likely to be found in waters that are deeper than 100 m, and especially in the Grand Manan Basin. In October, sharks were found primarily further south in the Gulf of Maine, in waters more than 200 m deep.
