Charleston weather in October is generally warm, comfortable, and much less humid than during the summer months, making it one of the best times of year to visit the city. Days are usually warm enough for summer clothing, while mornings and evenings can be pleasantly cool, especially toward the end of the month.
I'm not just a tour guide. My background as a retired meteorologist means I can give you a better idea of what to expect from the weather when you're planning a trip to Charleston in October.
What Is the Weather Like in Charleston in October?
October marks the transition from summer to fall in Charleston. The month typically begins with warm afternoons and mild mornings, while temperatures become noticeably cooler as November approaches.
Charleston's October climate averages a high of about 77°F (25°C) and a low of about 56°F (13°C).
Early in October, afternoon temperatures can still reach the low 80s°F (27–28°C), and occasionally the temperature can climb into the upper 80s or even around 90°F. By the end of the month, afternoon temperatures are more likely to be in the 70s°F (21–26°C), with mornings and evenings becoming considerably cooler.
So while you shouldn't expect consistently cool fall weather, October is generally much more comfortable for walking around Charleston than the hot and humid summer months.
Is October a Good Time to Visit Charleston?
Yes. October is an excellent month to visit Charleston.
The weather is generally comfortable for walking, sightseeing, and spending time outdoors. The oppressive summer heat and humidity have eased, but you can still expect plenty of warm days.
October is particularly good for exploring Charleston's historic district on foot. You can spend several hours walking between historic homes, churches, parks, markets, and other landmarks without dealing with the intense heat that can make summer sightseeing uncomfortable.
It's still worth remembering that Charleston is a coastal city. Warm weather can return at any point during October, and rain is always possible.
What Should You Wear in Charleston in October?
Packing for Charleston in October is relatively easy.
For daytime sightseeing, summer clothing usually works well, particularly during the first half of the month. Lightweight shirts, blouses, shorts, skirts, dresses, or lightweight pants are all appropriate for many October days.
You'll also want to bring:
- A light sweater or jacket for mornings and evenings
- Comfortable walking shoes
- An umbrella or lightweight rain jacket
- Layers that you can add or remove as temperatures change
If you're visiting toward the end of October, I'd be more inclined to pack a light jacket or sweater, especially if you plan to be outdoors after sunset.
And if you're taking a walking tour, comfortable shoes are more important than almost anything else!
Does It Rain in Charleston in October?
Yes, but October is not normally a particularly wet month.
Charleston averages roughly 5–6 days with measurable precipitation in October, with around 3 inches of total precipitation for the month.
That doesn't mean you'll lose several days of your vacation to rain. October weather can change quickly, and a rainy period may be followed by clear skies.
Because Charleston can experience periods of heavy rain, it's a good idea to have a backup plan for rainy weather. But don't let the possibility of rain discourage you from visiting in October.
Is Charleston Humid in October?
Charleston can still be humid in October, but the humidity is generally much more comfortable than it is during the summer.
You may notice humidity on warmer days, particularly early in the month, but the combination of cooler temperatures and shorter summer-like heat makes October much more pleasant for walking around the historic district.
If you dislike Charleston's hot, humid summer weather, October is a particularly appealing time to visit.
What Are the Temperatures Like in Charleston in October?
The biggest thing to remember about October is that the weather changes considerably over the course of the month.
Early October
Early October can still feel almost like summer.
Afternoon temperatures are commonly in the upper 70s or low 80s°F, while mornings are generally comfortable and mild. A warm spell can push afternoon temperatures considerably higher.
Mid-October
By the middle of October, temperatures generally become more comfortable for sightseeing.
Warm afternoons are still common, but mornings and evenings begin to feel more like fall.
Late October
Toward the end of October, daytime temperatures are more likely to be in the 70s°F, with cooler mornings and evenings.
This is when you'll be especially glad to have a sweater or light jacket with you.
