Castle Hayne experiences a noticeable shift in temperatures across its four distinct seasons. Summers, typically from June to August, are hot and humid, with average daily highs often reaching into the upper 80s to low 90s Fahrenheit (around 30-34°C). The heat index, which accounts for humidity, can make it feel even warmer, frequently exceeding 100°F (38°C). Winters, from December to February, are generally mild, with average highs in the 50s and low 60s Fahrenheit (10-17°C) and overnight lows usually staying above freezing. While freezing temperatures occur, prolonged deep freezes are uncommon. Spring (March-May) and Fall (September-November) serve as pleasant transitional periods, offering comfortable temperatures, often in the 60s and 70s Fahrenheit (15-25°C), with less humidity than summer.

Precipitation Patterns

Rainfall is abundant in Castle Hayne, distributed fairly evenly throughout the year, though summer often sees a slight peak due to convective thunderstorms. The annual average precipitation is around 55-60 inches (1400-1500 mm). Thunderstorms are common during the spring and summer months, often intense but brief. Tropical systems and hurricanes can also contribute significantly to the total rainfall, sometimes leading to localized flooding. Snowfall is rare, with most winters seeing little to no accumulation, and significant snow events occurring only once every few years. — Dutchess County Fair: Your Ultimate Guide
