Charleston weather facts every pet owner should know
- July afternoons in Charleston average 91.3F, above the 90F danger line for dog walks, so summer exercise belongs at dawn when lows near 73.7F are the coolest you will get.
- Nearly half of Charleston's annual rainfall arrives from June to September as thunderstorms, so keep a towel by the door and an eye on the radar before summer walks.
- Winter is prime walking season: January highs average 60.2F, comfortable for almost any breed without a coat.
- Measurable snow reaches Charleston about once a decade and the yearly average is just 0.3 inches, so paw booties here are for hot pavement, not ice.
