Answer
Summertime in Arkansas is typically very hot and humid, with temperatures often rising into the upper 80s to mid-90s Fahrenheit (around 30–35°C). The state’s humid subtropical climate means that high humidity levels make the heat feel even more intense, especially in July and August.
Arkansas experiences high humidity due to its proximity to the Gulf of Mexico and abundant vegetation. Average relative humidity frequently ranges between 70 and 90 percent during summer mornings, which gradually decreases but remains uncomfortable throughout the day. Cities like Little Rock, Fayetteville, and Hot Springs often see heat indices—what the temperature feels like when humidity is factored in—exceeding 100°F (38°C). This combination of heat and humidity can cause discomfort and necessitates precautions such as staying hydrated and avoiding strenuous outdoor activities during peak afternoon hours.
Key Points:
- Average summer highs: 88–95°F (31–35°C)
- High humidity levels, often 70–90% in mornings
- Heat index can exceed 100°F (38°C)
- Humid subtropical climate influenced by Gulf of Mexico moisture
