May 2023 dumped more than five inches of rain on Boulder and concluded as the 11th wettest May since the late 1800s. Though there were no exceptionally warm days, the month did see an above normal mean temperature, breaking a streak of cold months stretching back to November. Other monthly headlines included multiple severe weather outbreaks and of course the thick wildfire smoke from Canada which created days of degraded air quality. Here’s a quick and colorful graphical recap of our weather during May and how it relates to climatology.
