If you ask us, on a late-summer evening, which is our favourite month in Corsica, we’ll answer September without hesitation. The sea is at 24–25°C, warmer than in June. The campsite’s paths grow quiet again. The light turns golden, lower, softer. And prices come down. September is the Corsica we like to keep a little to ourselves — and that we’d love to share with you.
Why Corsica in September is such a good choice
The answer fits into one sentence: in September, everything that makes Corsica beautiful is still there, but without what makes it tiring in the middle of August.
The sea has spent the whole summer storing up heat. It releases it slowly, and it’s precisely in September that it’s at its best: between 24 and 25°C on the east coast, often warmer than in June, when it tops out at 20–22°C. You slip into the water without that early-season shiver. The children stay in for hours. So do the grown-ups, for that matter.
The eastern coast enjoys around 2,800 hours of sunshine a year and nearly 300 sunny days. In September, that sun is still there — just less overpowering. You can walk to the beach at three in the afternoon without seeking shade at every step. You can play pétanque in the late afternoon. You can go for a morning hike without setting off at six.
And then there’s the quiet. Not total silence — the cicadas hang on for a few more weeks, and the campsite is still very much alive. But a relative quiet, the kind that follows the great August wave. Families with school-age children have gone home. What remains are couples, retirees, travellers free of calendar constraints, and a few families with toddlers. The atmosphere becomes slower, friendlier, more Corsican.
The sea in September: what you need to know
Our campsite is 700 metres from the sea, in Ghisonaccia. The path that leads there runs alongside the canal, in the shade of the trees. In September, this walk becomes a real pleasure: no more scorching sand underfoot, no more stifling heat on the way back. You set off with a towel, come back with salty hair, and you’re not worn out.
The beach itself stretches for kilometres of fine sand. In August, it’s busy. In September, it’s not unusual to plant your parasol with fifty metres of empty space around you. The wind often drops at the end of the day, the sea turns glassy, and the sunset paints the mountains behind the campsite in pink and orange.
📍 Did you know? The canal running alongside our campsite flows into the sea. You can hire a kayak on site and paddle down to the river mouth — €15 for a single, €20 for a double, per half day. In September, the canal water is calm and the morning light on it is magnificent.
The campsite in September: a different rhythm
We stay open until 8 October. So September is a full month, with all the facilities up and running — but with an atmosphere completely different from July and August.
The two pools become places where you can really swim again, not just splash about in a crowd. The wooded grounds, with their tall pines and broadleaf trees, regain their natural coolness. The pitches of more than 100 m² feel even more spacious when there are fewer neighbours around.
Here’s what’s available in September:
The two swimming pools
Open throughout the season. In September, the water is still pleasant and the pools are finally peaceful — the perfect time for a few morning lengths.
Kayaking on the canal
€15 per half day for a single, €20 for a double. No guide, at your own pace. The canal flows into the sea: a nature outing to enjoy at daybreak.
Pétanque, table tennis, volleyball
The courts are free, and games spring up between pitch neighbours. It’s often in September that the best friendships are made.
The playground and table football
For children who haven’t started school yet, and for grown-ups who never really stopped playing.
The bar
Open all season. A drink in the late afternoon, an ice cream for the children, and conversations that stretch on until dusk.
The mini-market
For the morning bread, the basics and the inevitable forgotten items. Handy when you don’t feel like getting back in the car.
💡 U Casone tip: our restaurant is open 7 days a week from mid-June to mid-September. If you’re keen to dine on site — with our weekly themed evenings, moules-frites, paella or spit-roast veal depending on the week — aim for the first ten days of September. After the 10th, the pizzeria and the bar take over for simple evenings, and the mini-market stays open.
September, week by week
The month isn’t the same from start to finish. Here’s how we experience it from the inside.
1 to 10 September
The transition. The campsite empties gradually, but everything is still running, restaurant included. The sea is at its warmest. It’s our favourite window for families with young children.
10 to 20 September
The heart of our September. Deep calm, superb light, days that are still hot, and evenings that call for a light jumper. Couples and motorhome travellers adore this period.
20 September to 8 October
The Corsican autumn gently settles in. The sea stays around 22°C. Hiking becomes ideal. It’s the mildest and most affordable time of the whole season.

What to do around Ghisonaccia in September
September is the perfect month to venture beyond the campsite. The roads are clear, the sites are no longer overcrowded, and the temperatures finally make walking enjoyable. Here’s what we most often recommend to our guests:
- The Fiumorbo gorges — thirty or forty minutes’ drive away. Pools of clear water, smooth rocks, genuine mountain coolness. In September, you often have the place almost to yourself.
- The Étang de Diane — a few kilometres to the north. Here you can taste oysters straight from the oyster farmers, overlooking the water. A simple, deeply local experience, best enjoyed in the late morning.
- Corte — an hour’s drive. The citadel, the narrow streets, the Restonica and Tavignano gorges. Inland Corsica, the Corsica of mountains and history. A full day out.
- Porto-Vecchio and the southern beaches — around 1 hr 15. Palombaggia, Santa Giulia. In August, these beaches are packed and the road is jammed. In September, you get there stress-free and rediscover their original beauty.
- The Pinia forest — very close by. It’s the last great maritime pine forest on the Corsican coast. A walk in the shade, the scent of resin, the sound of the wind in the needles. Perfect in the late afternoon.
- The inland villages — Ghisoni, Vezzani, the hilltop hamlets of the Fiumorbo. Stone houses, fountains, shady terraces. September brings local life back after the summer whirlwind.
Who is September really made for?
Couples
It’s probably the month when U Casone is at its most romantic. A safari tent or a Luxury lodge beneath the pines, the evening light filtering through the branches, the canal a stone’s throw away, the beach almost deserted. You dine outdoors and stop looking at the time. There’s no rush.
Retirees and long-stay travellers
Many of our September guests are regulars who come every year at the same time. They arrive by motorhome or caravan, take a large pitch and stay for two or three weeks. The pace suits them: gentle warmth, accessible sites, a peaceful campsite.
Families with children not yet at school
If your children haven’t started school yet, September is a gift. Quiet pools, a peaceful beach, a free playground, shade everywhere, and a budget that’s noticeably lighter than in August. The walk to the beach, in the shade along the canal, is easy even with a pushchair.
Those travelling with their dog
We welcome dogs all season, including in our rental accommodation. And September is objectively the best month to come with a pet: the sand no longer burns their paws, walks are possible at any time of day, and there’s room everywhere.
Our practical tips for a September stay
💡 U Casone tip: pack a light jumper or a sweatshirt. The days stay warm, but from mid-September the evenings turn noticeably cooler once the sun has set. That’s lovely for sleeping — less so if you’ve only packed T-shirts.
A few other things we often repeat:
- Book your ferry early. September crossings are less in demand than August ones, but the end-of-month return sailings fill up. Allow €15 to €30 per animal if you’re bringing your dog.
- Pack the sun cream all the same. The September sun is gentler but still very much there. It’s the month when people get sunburnt because they’ve let their guard down.
- Keep one day unplanned. That’s the luxury of September: plan nothing, and see what the day brings.
- Do your shopping at the market. Local producers have more time and are less rushed, and the autumn fruit season is beginning. Charcuterie, brocciu, figs, grapes.
And the budget?
It’s the argument we don’t like to lead with, because we’d rather talk about the sea and the light. But it matters, and it’s real: September is noticeably more affordable than July and August, both for accommodation and for the ferry. For exactly the same thing — the same pitch, the same mobile home, the same safari tent — you pay less for a stay that many consider better.
In other words, we’re not offering you a watered-down version of summer at a discount. We’re offering you the best version of Corsica, at a time when fewer people are asking for it.
Frequently asked questions about Corsica in September
Can you still swim in Corsica in September?
Yes, easily. The sea is at 24–25°C on the east coast in September, and still around 22°C in early October. That’s warmer than in June. Swimming remains pleasant right up until the campsite closes on 8 October.
What’s the weather like in Ghisonaccia in September?
Sunny, warm days, generally between 25 and 30°C at the start of the month, a little less afterwards. The evenings are mild, then cool from the second half of the month. A few rainy spells are possible towards the end of the month, usually brief.
Is everything open at the campsite in September?
The pools, the bar, the pizzeria, the mini-market, kayaking and all the on-site activities run until the end of the season. The restaurant is open 7 days a week until mid-September.
Do you need to book far in advance for September?
Less so than for July and August, but we still recommend booking a few weeks ahead, especially for rental accommodation and the large pitches. The first half of the month remains in demand.
Is September suitable for families?
Yes, especially for families with children who haven’t started school yet, and for those who can travel during the first week. The campsite is calmer, the water is warm, and everything is easier — from finding a spot on the beach to the queue at the pizzeria.
A month we’d love you to discover
We’ve seen guests come in September by chance — a scheduling constraint, a late holiday — and then return every year at the same time. There’s something about this month that stays with you: the warm sea, the low light, the scent of the pines growing stronger with the first rains, the cicadas gradually falling silent, the campsite breathing easy.
U Casone means “the big house” in Corsican. In September, that’s exactly what it is: a big house where there’s room to spare, where you know your neighbours, and where nobody is in a hurry.
Our season runs until 8 October. Safari tents, chalets, Wooden lodges, Luxury lodges, mobile homes and large pitches beneath the pines: there’s still room for you to enjoy your Corsican September.
