- Whale migration: In January, the San Diego Bay and surrounding waters serve as a critical breeding ground for humpback whales. These massive creatures arrive in the area to give birth to their young and nurse them for several weeks.
- Sea turtle nesting: Sea turtles, which have traveled thousands of miles to reach San Diego’s beaches, take advantage of the January weather to lay their eggs safely above the high tide line.
The significance of these events cannot be overstated, as they contribute to the preservation of marine species and the integrity of the coastal ecosystem.
