August weather forecast
Louisiana, USA

August continues to uphold Louisiana's reputation for sweltering summers, with the month typically being the climax of the season's heat. The southern sectors, including prominent cities such as New Orleans, usually experience daytime highs oscillating between 90°F (32.2°C) and 94°F (34.4°C). In contrast, the northern portions of the state, covering locations like Shreveport, typically witness temperatures from 86°F (30°C) to 90°F (32.2°C).

As the sun sets, temperatures moderately dip, yet they remain quite warm. In southern Louisiana, nighttime lows gravitate between 71°F (21.7°C) and 75°F (23.9°C). The northern areas, while marginally more refreshing, also persist in maintaining warm nights, with temperatures settling from 67°F (19.4°C) to 71°F (21.7°C).

August sustains the pattern of regular rain events seen in previous summer months. The likelihood of afternoon thunderstorms remains high, characterized by potent, transient tropical showers. These sudden bouts of heavy rain often lead to localized flooding scenarios, especially in areas more prone to water accumulation.

When juxtaposed with July, August's temperature profile is quite similar, if not marginally cooler towards the latter half of the month. The oppressive humidity lingers, leading to a perceived temperature that can feel considerably hotter than actual readings. Moreover, August resides in the peak of hurricane season. Given Louisiana's vulnerability to these tropical systems, especially its coastal regions, it is paramount for locals and tourists to monitor weather updates and remain prepared for any potential storm threats. Notably, Plain Dealing recorded Louisiana's highest-ever temperature of 114°F (45.6°C) on August 10, 1936, emphasizing the month's potential for extreme heat.
