July 21, 2026 — A new study published by NOAA’s Fisheries’ Southwest Fisheries Science Center found that population numbers of gray whales along the U.S. West Coast have increased since 2025.
How and why populations of Eastern North Pacific gray whales are seeing an uptick is still under research, but in a release, NOAA confirmed that the increase “likely exceeds the reproductive capacity of the population.” Last year, the most recent estimate for gray whale calves was the lowest on record at 85. Now, researchers estimate the population of Eastern North Pacific gray whales is between 15,930 and 20,530, which is much higher than last year’s estimate of between 11,690 and 12,890.
