Broussard plays for keeps on both ends of the thermometer — 110° in August 2023 and 4° in January 2025 tell you this place doesn't do mild extremes. The wettest single day on record dropped a staggering 10.4 inches in August 2016, and even a 14-inch snowstorm showed up in February 1895, which feels almost mythological for south Louisiana.
Summer runs long and hot here, with highs in the low 90s from June through August and a peak average of 92° the last week of July into early August. If you're heat-averse, January is your best bet — highs hover around 62°, the coolest stretch of the year. July is the wettest month, so pack accordingly if you're visiting mid-summer.
