Weak La Niña Forecast for Winter 2024: What It Means for Austin’s Weather

As a weak La Niña begins to take shape this winter, Austin's climate is expected to be warmer and drier than usual. The 2024 U.S. Winter Outlook predicts that Texas will experience these conditions, as La Niña generally favors a northern storm track, keeping colder air out of the state. The Climate Prediction Center also suggests that drought conditions may worsen or persist across most of Texas throughout the season.

Though La Niña typically leads to warmer and drier winters, historical data shows mixed results for Austin. Research of four weak La Niña winters from the 1980s to 2010s reveals that three of those winters were cooler than average for the city, likely due to cold air outbreaks. While weak La Niña conditions tend to increase temperature and precipitation fluctuations, overall, these winters were drier than usual, with one notable outlier in the 1883-1884 winter.

The weak La Niña pattern is expected to increase fluctuations in the polar jet, raising the chances of sudden cold spells. However, overall, Austin residents should prepare for warmer and drier winter conditions, though precipitation may remain inconsistent across the season.
