Beneath the surface of the tropical Pacific Ocean at the equator, a deep pool of cooler-than-average (blue) waters has been building up throughout the summer to date (June 7-August 1, 2024). This pool of relatively cool water is a key factor behind the prediction for La Niña later this fall and winter.
