The Atlantic season runs June 1 to November 30. That is the calendar.

The season that actually threatens your boat runs roughly August 20 to October 20. That is the climatology, and it starts this week.

Why these sixty days

Hurricane season is not evenly distributed. It is not even close.

The overwhelming majority of major Atlantic hurricanes — and nearly all the ones that make landfall on the U.S. coast with real intensity — form inside a window that runs from late August through mid-October. The statistical peak sits in early to mid-September.

The reason is straightforward. Sea surface temperatures reach their annual maximum in late summer. Wind shear across the tropical Atlantic reaches its annual minimum. Waves coming off Africa are at their most frequent and best organized. Everything a storm needs lines up at once, and it stays lined up for about two months.

June and July storms tend to be homegrown, close to shore, and short-lived. What forms in September comes off Africa, crosses two thousand miles of warm water with nothing to disrupt it, and arrives as a completely different animal.

A quiet season does not change this

The 2026 season has been remarkably slow. NOAA’s August update raised the odds of a below-normal season to 75 percent, and through early August the basin had produced roughly three percent of median seasonal ACE.

None of that is a forecast for your dock.

A seasonal outlook predicts how many storms form. It says nothing about where any of them go. Landfall is decided by steering patterns that cannot be forecast weeks out, and a quiet year with one badly-aimed storm is worse for you than a busy year that stays offshore.

1992 produced seven named storms all season. One of them was Andrew.

What to actually do this week

Read your policy before you need it. Most marine policies carry named-storm provisions, haul-out requirements, and deductibles that differ from the standard ones. Some require a written hurricane plan on file. Find out now, not while you are watching a cone.

Confirm your haul-out. If your plan is to pull the boat, call the yard and confirm they can actually take you and how much lead time they need. Yards fill up in the order people called, and the calls start the moment a system gets a name.

Walk the ground tackle. Chafe gear, line condition, shackle pins, cleats and their backing plates. If you would not trust it in a sixty-knot gust, replace it in the calm.

Photograph everything. Deck, cabin, electronics, engine room, serial numbers. Ten minutes now is worth an enormous amount to a claims adjuster later.

Know your trigger. Decide in advance what forecast makes you act — a named storm inside a certain distance, a certain forecast track, a certain number of hours out. Deciding under pressure is how people end up doing nothing.

And the mistake to avoid

Do not let a slow summer talk you out of the work.

Every quiet season produces the same pattern: people relax through August, and the ones who get caught are the ones who were still planning to sort the ground tackle “next weekend.”

The forecast this year says fewer storms. It does not say none. And it never says where.

Sixty days. They start now.

See you on the water.
