The climate of Arkadelphia

Arkadelphia, located in the heart of Arkansas, has a humid subtropical climate, identified as 'Cfa' as per the Köppen Climate Classification. The subtropical moniker illuminates the abundance of humidity. The hallmark of this region is the lack of a dry season, which extends a welcome mat to rain throughout the year.

Perusal of the climate records reveals the fluctuating face of Arkadelphia's weather. Temperature highs oscillate from 50.5°F (10.3°C) in January to a toasty 93.2°F (34°C) in July. Correspondingly, lows vary from 34.3°F (1.3°C) in January to 71.8°F (22.1°C) in July. Although a study of these variations shows no drastic swings, it does highlight a steady increase from winter to summer and an equally unhurried decrease from summer to winter.

Arkadelphia's wet aspect is further underscored by the rainfall data. It registers an uptick from 1.26" (32mm) in January to a peak of 2.52" (64mm) in April. Then, it gradually loses ground, hitting a low of 1.14" (29mm) in September, before climbing again. A similar fluctuation is noted in the average number of rainfall days per month, rising from 8.1 in January to a high of 14.3 in August. The months of December to February are accompanied by infrequent, minimal snowfall. The city basks in the longest daylight hours in June with 14.4 hours, but by December, it is down to 9.9 hours.

The Best Time to Visit Arkadelphia

The details offer insight into the ideal time to visit. Consideration of various factors such as temperature, rainfall, and daylight hours culminates in the identification of late spring and early summer as the optimal period for a visit.

Rainfall during this time, between 2.09" (53mm) and 1.97" (50mm), does not pose a significant deterrent. The added allure of long daylight hours, from 14 hours to 14.4 hours, and a promising UV index ranging from 6 to 7 make this period particularly enticing.
