Many visitors may prefer coming to see Lafayette and Central Louisiana in the spring and late fall when the sometimes oppresive sub-tropical heat and humidity has not fully kicked in.   Even in January the low temperatures will stay in the manageable 40-50 degree range. Starting in February the temperatures will start to steadily rise, so that by March many days are back in the 60-70 degree range.
     By April and early May, temperatures will routinely start hitting the 80s and by June, daytime temperatures will be fairly lodged in the 90s. The  temperature will rarely ever fall below 70 during this period. Cooler fall temperatures usually take until around mid-October to set in.  Hot summer weather lasts well through September.
     Because of the humidity and wet terrain, the area gets more rain than most other places in the U.S. Plan accordingly if you are heading to Lafayette - and bring your bug repellent.  Late summer and early fall hurricane season is sometimes a major issue for Lafayette for the southern part of the parish is less than 25 miles from the coast. In most cases, a hurricane making landfall south of Lafayette will only weaken one category by the time it reaches the city, so stay abreast of hurricane information during hurricane season while in Lafayette.
