A Double-Dip La Nina Ahead in 2025

The International Research Institute (IRI) for Climate and Society released a collection of Nino34 SSTA forecasts for 2025 earlier today. The consensus of dynamic (and especially) statistical Nino34 SSTA forecasts is a trend toward a “double dip” La Nina for later this year. Previously, Climate Impact Company issued a Nino34 SSTA constructed analog forecast indicating a second La Nina later in 2025 somewhat more intense than the 2024-25 version.
