The summer tourists are long gone. The hotels are down to a fraction of their summer staff. Old Harbor has exactly the right number of people in it — enough to feel alive, few enough that you can hear the gulls and the water. The light hits the clay bluffs differently when the sun is lower in the sky, the vegetation along the Greenway has gone gold and rust, and the fishing is better than it was in July.
October on Block Island is an acquired taste. Once you’ve been, it becomes a tradition.
What Block Island Is Like in October
Block Island in October is small-town quiet — and for a certain kind of traveler, that’s the whole point. This is the island without performance. The restaurants that do stay open have the time to be themselves. The trails have no foot traffic. The ferry crossing feels like traveling to somewhere genuinely remote.
Accommodation availability is easy to find, rates are low, and the island’s natural beauty is at arguably its annual peak. Fall migration is still ongoing in early October — birders who come specifically for this typically consider early October as good as or better than September.
What October looks like:
- Daytime temps: 55–65°F
- Ocean temperature: 58–64°F (cold enough that swimming takes commitment)
- Crowds: Minimal. The island is functionally empty by mid-October on weekdays.
- Business hours: Many seasonal businesses close or reduce to weekends-only
- Light: The lower angle of the sun creates extraordinary golden-hour lighting, earlier in the day
Weather in October on Block Island
October brings the genuine feel of New England autumn. Block Island’s marine influence keeps it milder than the mainland — typically 5–8 degrees warmer than Providence or Boston — but fall is unmistakably fall.
Typical conditions:
- Early October (1–15): 60–65°F days, 50–55°F nights; occasional summer-like warmth with southwest winds
- Late October (16–31): 55–60°F days, 45–52°F nights; increasingly autumn
- Rain: October is more variable than September; occasional multi-day stretches of overcast/rain
- Wind: The south and west sides of the island can be genuinely blustery in October
The good news about October rain on Block Island: see the rainy day guide. There are enough covered activities, atmospheric restaurants, and genuinely enjoyable in-weather experiences that a day of rain isn’t ruinous.
Why October on Block Island Is Special
The Fishing
October is false albacore season — and albie season on Block Island draws fly anglers from across the East Coast. These fish show up in numbers in late August and run through October, sometimes into November. They’re fast, powerful, and notoriously difficult to fool — the challenge is what makes them legendary among fly rod anglers.
Beyond albies, October brings the fall striper run. Large striped bass move through as water temperatures cool, and surf casters on the island’s rocky southwest corner and around the bluffs have an excellent shot at trophy fish in the 30–40+ pound range.
This is the best month for serious fishing on Block Island. Period. See our Block Island fishing guide for specifics.
The Birding
Block Island in fall migration is one of the genuinely world-class birding destinations on the East Coast. The island’s isolation, the habitat diversity, and the geographic position create a situation where exhausted migrating birds pile up — sometimes in extraordinary numbers during weather events that ground them.
October brings the peak of sparrow migration, late warblers, thrushes, and an excellent shot at rare vagrant species from the west that get displaced and end up on Block Island. The Block Island Bird Banding Station at Clay Head typically runs through October.
If you have any interest in birds, early-to-mid October on Block Island is worth specifically planning around.
The Light
The angle of the sun in October produces light that photographers — particularly landscape and travel photographers — specifically seek out. The clay bluffs at Mohegan Bluffs go warm amber in afternoon light. The ponds and marshes reflect sky in ways they don’t in the flat light of midsummer. The vegetation along the Greenway trails has turned.
Golden hour on Block Island in October starts earlier — around 4:30–5 PM — and lasts longer proportionally. If you care about photography at all, October gives you the best light of the year.
The Quiet
There’s a specific pleasure in having Block Island feel genuinely remote — not crowded-remote like a busy hiking trail, but actually quiet. In October on a Tuesday, you can walk the Clay Head trail and see no one. You can sit at the Mohegan Bluffs overlook with the ocean below and no other cars in the parking area. The Old Harbor ferry dock has a handful of people on it, not a queue.
For travelers who specifically want to experience what Block Island is rather than what Block Island performs for summer visitors, October delivers it.
Things to Do on Block Island in October
Fishing
Peak season for false albacore and fall stripers. Hire a charter for guided offshore action, or surf cast independently from Southwest Point and the south shore. See the fishing guide.
Birding on the Greenway
Walk Clay Head, Rodman’s Hollow, and the central ponds. Bring binoculars. Go in the morning. October can produce exceptional single-day bird counts — 30+ warbler species on a good wave day, sparrows in every brushy edge, raptors moving along the coast.
Hiking the Mohegan Bluffs and Greenway Trails
The hiking trails in October are beautiful and empty. The Rodman’s Hollow loop to Black Rock Beach is particularly striking with the vegetation turning. The Mohegan Bluffs staircase is manageable without the summer heat making the climb back up punishing.
Cycling
The island in October is quiet enough that cycling feels genuinely exploratory rather than recreational. Rent a bike and take your time — there’s no traffic pressure, no hurry. Bike rentals are typically available on weekends through October; confirm mid-week availability before planning around it.
Restaurant and Inn Evenings
The October dining scene on Block Island is smaller than summer — some restaurants have closed for the season — but those that remain are often doing their best work. After the summer sprint, chefs and staff have time to cook deliberately. The atmosphere in a near-empty Block Island restaurant in October, fire lit, ocean wind outside, is genuinely excellent.
What’s Open in October
This is the key practical planning question. The honest answer is: it depends on the year and the specific date within October.
Generally open in early October:
- Major restaurants (though reduced hours)
- Bike rentals (weekends reliable; mid-week less so)
- Ferry service (Point Judith route reliable through October)
- Some accommodations
Increasingly uncertain in late October:
- Many seasonal restaurants and shops close after Columbus Day weekend (mid-October)
- Bike rental shops may be weekends-only or closed
- The Block Island Express ferry from New London typically ends service by mid-October
Reliably open:
- Point Judith ferry service
- Block Island State Airport (if flying)
- A few year-round accommodations and restaurants
The practical advice: call ahead. October operations on Block Island are genuinely variable year to year. Confirm that your planned restaurant, rental shop, and accommodation are operating on your specific dates before you book the ferry.
Ferry Access in October

What to Pack for Block Island in October
- Layers: The layering approach is essential in October. Start in a mid-layer, add a warm outer layer for mornings and evenings.

- Wool or fleece mid-layer: Not optional by late October
- Waterproof boots or trail shoes: Trails can be wet
- Binoculars: Migration is ongoing — bring them
- Camera with a real lens: The October light rewards it
