Hurricane Season Runs June 1 to November 30. What That Means for a Beach Week

The Atlantic hurricane season opens June 1 and closes November 30. On a flat, low barrier island with one road across the marsh to the mainland, the dates matter less than the shape of the risk inside them. August through October is when Beaufort County has decisions to make. The opening six or seven weeks of the season rarely produce any.

One island, one evacuation zone

Beaufort County does not slice itself into lettered sub-zones the way some coastal counties do. If the Governor orders an evacuation, the order covers the whole county, Hilton Head included, and it is not advisory. Evacuating traffic leaves on both William Hilton Parkway and the Cross Island Parkway toll facility, with the inbound side of US-278 reversed to add a third outbound lane on the mainland approach. The plan works. It also takes hours, and it is not something you want to be reading for the first time with a storm cone on the television.

What this changes about booking

• Book refundable where you can, and read the rental's storm clause before you pay. The trigger phrase is usually "mandatory evacuation order", not "hurricane".
• Insurers treat a named storm as a foreseeable event, so a policy taken out once the cone is on the television will not pay for that storm. If you want the cover it goes on the day you book, not the week you travel.
• September is the statistical peak of the season and also one of the better-value months on the island, with warm water and thinner crowds. That is a real trade-off and you should make it deliberately rather than by accident.

If you are already here

Sign up for Beaufort County emergency alerts when you arrive. Find out where your rental keeps its shutter and shut-off instructions. Keep the tank above half through late summer, because the queue at the bridges is a poor place to discover otherwise. If an order comes, leave early and drive 20 to 50 miles inland rather than trying to book a coastal hotel one county north.

Most tropical weather here is not an evacuation. It is two grey days, a squall that comes in sideways off Port Royal Sound, a red flag at the beach access, and dolphins still working Broad Creek on the falling tide. Plan for that version, and keep the other one in your back pocket.
