Little Rock, Arkansas, experiences a humid subtropical climate shaped by its inland location and proximity to the Arkansas River Valley. Understanding local weather helps residents and travelers plan effectively across seasons. This guide explores the city’s weather year-round, key seasonal shifts, and practical tips for staying prepared.

Spring in Little Rock: Warming Up with Precipitation

Spring, from March to May, brings mild temperatures averaging 50°F to 75°F, ideal for outdoor activities. However, this season is marked by frequent afternoon thunderstorms—driven by warming air masses colliding with cooler fronts. According to NOAA data from 2024, Little Rock averages 14 rainy days in spring, with occasional heavy downpours that can lead to flash flooding. Humidity levels rise steadily, making the air feel warmer than the thermometer shows. Early spring may still bring cold snaps, with overnight lows dipping near 40°F, so layered clothing remains essential.

Summer Heat and Humidity

From June to August, Little Rock enters its hottest and most humid season. Average daytime highs reach 85°F to 95°F, often pushing into the 100°F range. Combined with relative humidity above 60%, heat index values frequently exceed 105°F, increasing health risks like heat exhaustion. Thunderstorms remain common, especially in late summer, fueled by intense solar heating and moisture from the Gulf of Mexico. Local reports note that July typically sees the highest rainfall totals—averaging 4 to 5 inches—with brief but powerful downpours that can disrupt travel.

Autumn: Transition to Cooler, Drier Days

September to November brings a welcome shift. Temperatures gradually decline from summer highs, averaging 70°F to 85°F, and humidity drops significantly. Rainfall decreases steadily, with October often the driest month, ideal for outdoor events and travel. Fall foliage paints the region in warm colors, enhancing Little Rock’s scenic beauty. Light wind and clear skies create comfortable conditions for hiking, biking, or exploring parks like William V. Hart Park. This season balances warmth and cool, making it the most pleasant for visiting or living year-round.

Winter Chill: Cooler and Occasionally Snowy

Winter spans December through February, with daytime highs between 45°F and 60°F and nighttime lows averaging 25°F to 38°F. While snow is rare and usually light, occasional winter storms dump 1 to 3 inches of snow, creating picturesque landscapes and seasonal activities. Cold fronts can bring brief periods of freezing rain or sleet, particularly in January. Wind chills may drop below 20°F during prolonged periods, emphasizing the need for warm layers and winter preparedness. Despite the cold, winter nights offer crisp, clear skies perfect for stargazing.

Climate Trends and Future Outlook

Climate data from 2023–2025 indicates a subtle but measurable warming trend in Little Rock, with average annual temperatures rising by approximately 1.2°F over the past decade. This shift aligns with regional patterns linked to global climate change, affecting rainfall distribution and intensifying summer heat. Local environmental studies suggest increased frequency of extreme weather events, including more intense thunderstorms and longer dry spells. Residents and visitors are encouraged to stay informed through real-time forecasts and prepare for variable conditions beyond typical seasonal norms.
