The Last Warmth: Sussex Coast in September

September arrives on the Sussex coast like a long exhale.

The crowds have thinned. The beach huts are padlocked by mid-morning. The sea, still warm from three months of summer sun, is often at its most swimmable now — clearer than July, calmer than August, with a quality of light on the water in the early evening that is so particular to this month that I have come to think of it as September light, belonging to no other time. The chalk cliffs hold the warmth of the day long after the air has cooled. Sitting with your back against them in the late afternoon, you can feel the whole accumulated heat of summer stored in the rock behind you, releasing slowly, generously, as if the land itself is sharing what it has gathered.

This is the month I love most on the Sussex coast. It is the month of the harvest — not the harvest of fields and combines, though that is happening inland, but the quieter harvest of the hedgerow and the cliff edge and the dune system. Everything that has been slowly accumulating through the long months of growth is now ready. The landscape is at its most generous precisely as it prepares to withdraw.

The sea buckthorn harvest

In October the sea buckthorn (Hippophae rhamnoides) berries will be fully ripe, but September is when I begin to watch them carefully, checking the colour shift from green to the first hints of amber and orange along the dune ridges. These berries are extraordinary — among the most nutritionally concentrated foods growing wild in Britain, dense with vitamin C, carotenoids, omega-7 fatty acids, and a range of antioxidant compounds that have made them the subject of serious research interest in recent years. They taste fierce and bright and almost shocking, nothing like the polite sweetness of cultivated fruit. They taste like the sea wind and the salt air and the particular toughness of a plant that has spent its entire life on exposed shingle in all weathers.

I use sea buckthorn berries in tincture, in oxymel, in syrup — but I also think of them as terrain medicine in the most literal sense. They are what this landscape produces when it is left to do what it does best. Taking them feels like taking a small concentrated dose of the coast itself.

Blackberries at their peak

The blackberries (Rubus fruticosus agg.) that were just beginning in August are at their full richness now. The best ones on the Sussex coast grow in the sheltered combes cut into the chalk, where the brambles have sprawled undisturbed for years and the fruit is large and deeply flavoured. September blackberries have a complexity that the early August ones do not — a slight tartness beneath the sweetness, a depth that comes from slow ripening through the long summer days.

I gather blackberry leaf for medicine throughout the year, but September is when I make blackberry vinegar — a simple preparation of fresh berries macerated in good apple cider vinegar, sweetened lightly with honey, and left to steep until the liquid is deep purple and richly flavoured. It is one of the most useful things in my dispensary through the winter months: astringent, antimicrobial, gut-supportive, and deeply pleasant to take. It is also, in some way I find difficult to articulate precisely, a way of carrying September with you into the dark months. A jar of blackberry vinegar made on a warm afternoon above the cliffs is a form of stored light.

Elder in transition

The elder (Sambucus nigra) along the hedgerows at the cliff edge is heavy with berries now, the branches bowing under their weight, the clusters deepening from red to near-black as the month progresses. Elderberries are one of the most well-researched of the traditional hedgerow medicines — antiviral, immune-supportive, rich in anthocyanins — and September is the month to gather them, before the birds take everything and before the first frosts soften them beyond usefulness.

But I always pause with the elder in September before I gather. It is a plant with a long ceremonial history in these islands — a plant that was never cut or taken from without acknowledgement, without some gesture of respect toward what was being received. I do not think this is superstition. I think it is the accumulated wisdom of people who understood that their relationship with the plants around them was reciprocal, that taking without attention was a different act from taking with full presence.

September asks for full presence. The warmth will not last much longer. The light is already different — lower, more golden, more obviously temporary than the high white light of July. The nervous system, if we let it, begins its own shift now: a slowing, a softening, a natural movement toward interiority that mirrors exactly what the landscape is doing.

The gift of the turning year

There is a particular freedom in September on the coast. The summer's demands are behind you. The winter's demands have not yet arrived. There is a week, sometimes two, of pure threshold time — warm enough to swim, quiet enough to think, the harvest at hand, the pace gentled.

This is the coast's last great gift before autumn closes in: a moment of stillness between one season and the next, generous and unhurried, asking nothing except that you show up and receive it.

Go slowly. Fill your basket. Watch the light on the water.

It will not look like this again until next year.
