Gray whale migration season has concluded, and we are reflecting on an unforgettable few months along the coast! We experienced stunning close encounters, rare behaviors, and meaningful observations that remind us why gray whale migration is one of the most incredible wildlife events on Earth. Gray whales endure the longest migration compared to any other mammal! Every year, these gentle giants undertake an epic journey from their Arctic summer feeding grounds to their winter breeding grounds in the warm lagoons of Baja California. Our San Diego coast is located along their migration path so we are lucky enough to witness these transient whales each year! This year, we witnessed gray whales traveling closely along our coastline, each with their own unique story.
Migration Highlights
The annual gray whale migration is one of the longest of any mammal. They travel anywhere between 10,000 – 14,000 miles per year! Here are some of the highlights from this season:
- Record Numbers: This year, we observed a 27% increase in the number of whale sightings compared to last year!
- Calf Sightings: We witnessed numerous sightings of mother whales with their calves, a heart-warming reminder of the circle of life. However, recent research has noticed a decline in the number of cow/calf pairs compared to previous years likely due to food scarcity which may be hindering females from having enough energy to sustain themselves & reproduce.

- Close Encounters: We shared so many close encounters with friendly gray whales, some even displaying intriguing behavior such as rolling over and exposing their under bellies, acting like giant sea puppies! We have also seen a good amount of full body breaches!
Impact of Conservation Efforts
The recovery of the gray whale population is a testament to successful conservation efforts. Once on the brink of extinction, these whales have reached carrying capacity in previous years! However, we have observed a noticeable negative impact to gray whale sightings that could be correlated to lack of food due to melting of sea ice reducing their prey population of benthic amphipods.
Observations and Research
This season also provided valuable opportunities for researchers to study gray whale behavior, migration patterns, and overall health. The data collected will contribute to ongoing conservation strategies and help ensure the future of these incredible animals.
Looking Forward
As we bid farewell to the gray whales for now, we eagerly await their return next season. The journey of the gray whales is a reminder of the interconnectedness of nature and the importance of preserving our oceans. We hope to see even more whales next year!
