Glenn Zimmerman’s 2026 Spring Outlook March March is a tricky month, and one that sells itself as a spring month. But a lot of times it is much cooler than you want it to be. Marches have been trending warmer, but after the cold winter months, probably not as warm as you would like. I think this month is split with the beginning of the month calm and generally dry. We are in the middle of a global shift from La Niña to a neutral pattern, which generally indicates stormy weather.
