June weather in Charleston
Real heat — around 29°C / 84°F by day, so pace the afternoons and carry water, with rain on about 17 days, so keep a layer handy. The days are long too — close to 14 hours of light — so the evenings stay open for walking once the heat drops.
- Charleston gets rain on about 17 days in June, so the odds of being caught out are real. What earns its bag space is a shell that packs to nothing, dries fast and has a hood that survives wind; a heavy waterproof is overkill and an umbrella is one more thing to carry through crowds.

Is June worth it in Charleston?
Heavy crowds and only poor weather to show for it — a poor trade. For better value, come in September or March.
