Paradise Island in September: Weather, Sea, Crawfish Season and What to Do

In September the afternoons on Paradise Island build slowly toward a thunderstorm, the sky over Nassau Harbour turns the color of slate, and then the rain sweeps through and the pavement steams under the palms. By evening the light is soft and gold again and the bridge traffic hums. It is a warm, quiet-feeling month on the island, with crawfish on the menus and the resort pools and the harbor all to enjoy between showers.

What is the weather like in Paradise Island in September?

Come September, you get heat, humidity, and showers, mornings full of sun, a strong chance of heavy rain later on, and evenings warm enough for dinner outdoors in just a T-shirt.

Month	Average high (°F)	Average low (°F)	Rain days	Sea (°F)
August	91.0	76.4	14.4	87.6
September	89.9	76.0	13.3	86.7
October	87.1	74.1	10.1	84.6

If you step onto Paradise Island across the harbor, the warm, heavy air you feel is the same air that wraps around Nassau. Mornings are the best stretch for anything outdoors: the sun is bright, the air is heavy but not yet punishing, and the sea is most inviting. By early afternoon the heat builds, clouds stack up, and a shower or a loud storm is common.

Rain in September usually arrives as a burst rather than a gray, all-day drizzle. It can pour hard for a while, then clear, leaving the evening open for a walk or a dinner on a terrace. Rain falls on a good share of days, so plan the outdoor hours early and keep an indoor card for the middle of the afternoon.

Light, breathable clothes do the job, with a thin rain jacket or a small umbrella in the bag. In the middle of the month, you get a bit more than twelve hours of daylight, which means evening falls early. September also sits at the busiest stretch of the Atlantic hurricane season, so keep an eye on the forecast as the trip nears.

Can you swim in Paradise Island in September?

In September, after a hot morning, the ocean stays warm enough for a long, leisurely swim, almost like bathwater.

Paradise Island is ringed by beaches on its north shore and by the calmer harbor side facing Nassau. The Atlantic-facing stretches can carry waves on some days, and the weeks around the peak of the hurricane season can send swell in from distant storms. Expect the water to feel different from one beach to the next, and from one morning to the next.

Mornings tend to be the pleasant time to be in the water, before the afternoon clouds gather. Pack a hat or a rash guard to handle the intense sun, plus a mask in case you enjoy watching fish by the shore. Because the weather shifts quickly this month, it helps to leave the water when a storm cell approaches and to keep the swim flexible rather than fixed to one hour.

What to do in Paradise Island in September

September’s own flavor here is food and quiet: crawfish season began on August 1 and runs to March 31, so the Bahamian spiny lobster is fresh on plates all month. Between showers, the island rewards slow days, long lunches and a pace that the summer-heat schedule almost forces on you.

Ask for crawfish in its local ways. In Nassau you will find it everywhere, served cracked and fried, grilled, or mixed into a chilled salad with onion, sweet pepper and lime. On menus, crawfish and lobster can appear under one name, while every other kind gets its own label. In the harbor’s opposite direction, Gone Fishing on Arawak Cay serves a brown gravy lobster stew for breakfast.

Atlantis, rain or shine

Atlantis is what Paradise Island is known for, with its water park, pools, beach, restaurants, walk-in aquarium and casinos. In a showery month it suits the plan well, because so much of it is built around water and you are already wet. The water park, Aquaventure, includes The Current, which works as both a lazy river and a raft ride, plus the Mayan temple slide tower and its Leap of Faith drop.

Go to the slides and the river in the morning, when the sky is clearest, and keep the aquarium and the shops for the hour a storm rolls in. Families, couples and groups of friends all find something to fill a day here, and nobody has to leave the property to eat.

Dolphin Cay and the marine habitat

The marine side of Atlantis is a draw in any weather. Spanning 14 acres, Dolphin Cay is billed as one of the biggest and most advanced habitats and rescue and rehab facilities of its type. The resort also calls its habitat the largest open-air one in the world.

Swimming with dolphins is among the experiences offered there. The aquarium corridors and lagoons are good for a wet afternoon, when the beach is out of the question and children need somewhere to look and wander.

A golf course on an old runway

The island once had its own airport, closed in 1999, and the former airfield is now an 18-hole golf course. Early morning is the sensible tee time in September, when the sun is low and the grass still holds a little coolness.

Even if you do not play, the open green space is a change from the resort towers. Walkers and photographers like the light here at the start of the day, before the clouds pile up over the harbor.

Two bridges link the island to New Providence over Nassau Harbour, so a lunch or an evening in Nassau town is a matter of crossing the water. Arawak Cay, with its row of seafood stands, is the natural stop for a lunch of crawfish.

A two-day itinerary for Paradise Island in September

Day 1 belongs to Atlantis. Start at the beach right after breakfast, while the sun is bright and the sea is at its warmest, and swim and walk the shore before the heat settles in. Move to Aquaventure for the river and the slides through late morning, then take lunch at one of the resort restaurants as the clouds begin to build.

When the afternoon storm rolls in, move inside to the walk-in aquarium and the marine habitat, then linger over shopping and a good long rest. Sunset falls early evening at this time of year, with a little over twelve hours of daylight, so dinner on a terrace after the rain makes a good close.

Day 2 starts on the old airfield with a round of golf at first light, or simply a walk across the green. Return for a slow breakfast, then cross one of the bridges to Nassau and Arawak Cay for a crawfish lunch among the seafood stands, with a stew lobster for the adventurous.

Spend the afternoon wandering town when the showers have passed, or sit out a downpour over a cold drink. Come back to the island for the evening and a last dinner of grilled crawfish by the harbor, with the lights of the bridge reflected on the water.

Is Paradise Island busy in September?

September is one of the calmer months on the island, with fewer vacationers than in winter and a relaxed feel at the pools and restaurants.

School is back in session for many American families, so the weeks of heavy family travel are behind. What remains is a quieter mix of couples, groups and travelers happy to trade a stormy afternoon for room to spread out. Resort pools and beach spots are easier to settle into, and restaurant tables are usually simpler to find than in the high season.

Because the month falls in the heart of the hurricane season, plans are best made with some flexibility, and the Bahamas Ministry of Tourism and Aviation tracks tropical storms in the Atlantic and posts updates. Booking a little ahead is still a good habit for a favorite restaurant or a particular room, but there is no rush as there would be for the winter holidays.

Atlantis is advertising savings of as much as 35 percent right now on stays of four nights or longer, plus a resort credit and breakfast for two, a package that fits a month when you have more choices.

What to pack for Paradise Island in September

Think light, quick-drying and ready for a sudden shower between sunny stretches.

For those afternoon downpours, bring a compact umbrella or a light rain jacket.
Pack two swimsuits when you can, letting one dry as you wear the other.
For the intense morning sunshine, pack a wide-brimmed hat along with sunscreen.
Sandals that handle wet pavement, since showers leave the walkways slick.
A light layer for air-conditioned restaurants and the aquarium.
A dry bag for phones and cards at the water park.

Good to know before you go

The U.S. State Department rates the Bahamas Level 2, “Exercise increased caution”, and says most crime occurs in Nassau on New Providence and in Freeport on Grand Bahama.

September sits at the busiest stretch of the Atlantic hurricane season, which runs from June 1 to November 30, with the peak on September 10. Travelers are urged by The Bahamas Ministry of Tourism and Aviation to visit the hurricane page at Bahamas.com for updates, and the ministry keeps watch on storms.

A Bahamian visa is not required for U.S. citizens who visit. Everyone who comes in has to carry a passport, and according to the Bahamas Department of Immigration, that passport must remain valid for no less than six months. Travelers should also have a return or onward ticket on hand and might need to prove they have enough money.

Paradise Island in September vs August and October

Moving a month earlier brings the hottest air and the warmest sea, with more rainy days and longer evenings of daylight. August is also the first month of crawfish season, so the lobster is just arriving, though the weather is at its stickiest.

A month later, October is a touch cooler, the sea is a little less warm, and the number of wet days drops noticeably. Daylight shortens, so evenings arrive sooner, but the storm-season edge softens as the month goes on.

Choose August if you want the warmest water and do not mind showers. Choose September if you like quieter days and a lower-key resort. Pick October if you would rather have fewer wet afternoons, and still want crawfish on the menu.

Is September a good time to visit Paradise Island?

Yes, for travelers who like warm water, a slower pace and room at the resort, and who are comfortable building a day around a possible afternoon storm.

It suits families who want Aquaventure and the aquarium without winter crowds, couples looking for long dinners and quiet beach mornings, and food lovers who want crawfish in season. It is a poorer fit for anyone who needs reliably dry afternoons or whose dates cannot move if a storm threatens the forecast.

On arrival, spend the first sunny morning at the beach and in the water, and keep the indoor attractions for the first storm. The month’s own pleasure is the hour after the rain, when the harbor shines, the air smells of wet palms and a plate of crawfish arrives at the table.
