A hot, humid subtropical climate

Daniel Island shares greater Charleston's humid subtropical climate: hot, humid summers, mild winters, and roughly 48-55 inches of annual rainfall concentrated April through October (regional climate sourcing, retrieved 2026-08-24).

Real, documented storm-surge exposure given its river-bordered position

Daniel Island sits between the Cooper and Wando Rivers, making it genuinely vulnerable to storm-surge flooding during hurricanes. Hurricane Irma (2017) hit at high tide, delivering the greatest storm surge the island had seen at that time and ripping away a portion of a dock on the Wando River near Children's Park (The Daniel Island News, retrieved 2026-08-24).

A master-planned stormwater design with a real, comparatively strong track record

Daniel Island's deliberately master-planned stormwater infrastructure is credited with a comparatively 'good report card' after Irma relative to some other Charleston-area communities -- though this does not eliminate real, address-specific flood-zone exposure documented on the housing and taxes-insurance topic pages.

Key takeaways

Daniel Island shares the Lowcountry's hot, humid subtropical climate and real regional hurricane exposure common to this entire batch.
The island's position between the Cooper and Wando Rivers creates real, documented storm-surge vulnerability, evidenced by Hurricane Irma's 2017 impact.
A deliberately master-planned stormwater design is credited with a comparatively strong post-storm recovery track record, though real flood-zone exposure still varies by specific address.
