La Nina conditions were recorded in the fall of 2021. This is the second consecutive year of La Nina conditions. La Nina occurs when oceanic temperature anomalies along the equatorial Pacific Ocean region are below normal for an extended period. This results in cooler temperatures in British Columbia and wetter weather on the South Coast and on Vancouver Island.
Seasonal forecasts from Environment and Climate Change Canada show an increased likelihood of cooler temperatures around the province from February to April.
