Charleston Weather, When to Go and Climate Information

(Charleston, West Virginia - WV, USA)



West Virginia's capital of Charleston features an appealing four-season climate, which is both humid and subtropical in character.

The weather in the city is especially mild and pleasant, with temperatures usually being amongst the highest in the whole state. This is due to the city's situation, as it is somewhat protected by the elevated landscape to the east.

The end of March is when the springtime climate begins to make itself known. Daytime temperatures start to rise above 15°C / 59°F and daylight hours lengthen. However, from March to May, the weather in Charleston is particularly variable and temperatures can fluctuate wildly, due to extremes of wind, rain and sun.


Seasonal Climate Variations / When to Go

As May begins to approach June, the Charleston climate settles down and temperatures rise sharply, regularly topping 25°C / 77°F in June, and approaching 30°C / 86°F in July and August, the city's two hottest months. On the sunniest days, highs in the region of 35°C / 95°F are not unheard of.

It is worth noting that summer highs are often accompanied by noticeable spells of high humidity. From late spring onwards, there is a greater chance of thunderstorms, with the most severe even causing a subsequent tornado, although this is not commonplace.

The autumn weather in Charleston soon begins to cool down, both by day and by night. Evenings can feel quite crisp in October, when you will need warmer clothing if you are out and about after hours. December, January and February see the worst of the winter climate. While daytime temperatures generally stay at least a few degrees above freezing, frosty nights can be expected, along with snowfall, anytime from late November to March or even the early part of April.
