This past winter, Puerto Vallarta recorded a decline of over 50% in Humpback whale arrivals according to Deep Blue Conservancy. A chief researcher recorded less than 400 of the whales in the Bay of Banderas compared to a normal year where more than 1000 are observed.
Stumping researchers was also how much further from the coast the whales remained, and the amount of time the whales stayed under water. Typically the whales emerge every half hour on average, but this year researches stated that they documented dives of over an hour.
