The Complete Seasonal Guide to Oceanside Whale Watching
Winter Months (December – February): Gray Whale Migration Season

- Species: Primarily California gray whales
- Behavior: Steady southward migration to breeding grounds in Mexico
- Success Rate: 95%+ whale sighting probability
- Weather: Cool temperatures, occasional rain, calmer seas
Why Visit in Winter: Gray whales travel close to shore during their migration, often passing within just a few miles of Oceanside’s coastline. Mothers with calves make the return journey north starting in February, offering incredible opportunities to witness these tender family moments.
Spring Months (March – May): Peak Whale Watching Season
