About Webster Parish Weather
Moderate Southern Heat with Northern Influence
Webster Parish has an annual average temperature of 65.3°F, which is warm by national standards but cooler than the Louisiana coast. Its humid subtropical climate is influenced by its northern position, leading to more distinct seasonal shifts. This parish experiences more varied weather than the southernmost parts of the state.
One of Louisiana’s Cooler Parishes
At 65.3°F, Webster Parish is nearly two degrees cooler than the Louisiana state average of 67.0°F. It ranks as one of the cooler parishes in the state, particularly during the winter months. This is largely due to its proximity to the Arkansas border and greater exposure to continental air masses.
Drier and Snowier than Southern Louisiana
Webster receives 56.0 inches of annual precipitation, making it significantly drier than the state average of 60.8 inches. It also sees more snowfall than southern parishes, averaging 0.6 inches compared to the 0.1 inches seen in Vermilion. The July average of 83.5°F is actually higher than many coastal areas, showing more extreme seasonal swings.
Hotter Peak Summers and Chilly Winters
July is very hot with an average of 83.5°F and 88 days topping 90°F. Conversely, January is noticeably cooler than the south at 46.0°F. The parish sees a significant seasonal range, with summer averages of 82.4°F dropping to a winter average of 47.9°F.
Prepare for Seasonal Temperature Swings
Residents need to winterize pipes for the 46.0°F January average, which is colder than most of the state. During the 88 days of extreme heat, cooling systems will work hard to counteract the 83.5°F July peaks. The lower rainfall of 56.0 inches means drought conditions may be a more frequent concern than in the south.
