I have never been brilliant with ferries, and the crossing from Rodbyhavn to Puttgarden did nothing to improve my record. We had booked a summerhouse in Marielyst for a week in late May, timing it carefully to beat the Danish school holidays and catch that sweet spot when the Baltic has warmed just enough to contemplate a paddle without losing all feeling in your toes. What I had not timed carefully was my own stomach. Three coffees and a dodgy petrol station pastry combined with gentle Baltic swells to create a moment of personal humiliation that my partner has already committed to memory for future wedding speeches. I emerged from the toilet looking, as she put it, like I had personally negotiated Denmark's secession from Germany.

The drive down through Lolland and across to Falster gave me time to recover. The late May light was doing that magical Scandinavian thing where it stretches the afternoon into something seemingly endless, golden and soft across the flat fields. Rapeseed was out in violent yellow bursts between the greens, and the whole landscape felt freshly awake, not yet battered by the summer crowds that would descend in another fortnight. You could feel the season hovering, uncertain, between spring's last breath and summer's proper arrival.

Marielyst itself appeared gradually, a scattering of wooden houses through pine trees, the kind of place that reveals itself in pieces rather than announcing itself with any grandeur. Our summerhouse sat down a sandy track, and I will confess that my first thought upon opening the car door was not poetic. It was: "Blimey, that's fresh." The Baltic wind, even in late May, carries a reminder that Denmark sits at a latitude roughly level with Aberdeen. The sunshine might look inviting, but it comes with conditions attached.

The house itself was pure Danish holiday architecture, all pale wood and angles designed to catch light while somehow never quite getting too warm. I loved it immediately. The pine cladding smelled of last year's summer, that particular resinous memory of barbecues and salt and sun cream. But it was the outside that demanded attention first. The terrace, the little garden, the path through the dunes that we could already glimpse. Everything spoke of summer living, of days measured in beach trips and evening grills, of a rhythm entirely different from our usual frantic pace.

Yet late May would not let us forget its particular character so easily. That first evening, we sat on the terrace with wine and determination, watching the light linger past nine, feeling clever about our timing, our beating of the crowds. Then the temperature dropped with the sun, and we found ourselves in jumpers, then blankets, then a slightly undignified retreat indoors where the wood-burning stove suddenly seemed less decorative feature and more survival necessity. My partner looked at me with that particular expression. "Beach weather," she said, "is apparently a state of mind."

She was not wrong, and that became the lesson of the week. The seasonal limbo shaped everything. Mornings often arrived grey and stubborn, the sea looking distinctly uninviting, and we would plan indoor days, board games, slow cooking, hygge in its most deliberate form. Then by midday the clouds would tear open, the temperature would climb ten degrees, and we would rush to the beach like children given an unexpected holiday, knowing it might not last. The water remained a challenge, that sharp Baltic greeting that takes your breath and your dignity, but we swam anyway, because late May swimming feels earned in a way that August swimming never quite does.

The local shops operated on similar seasonal uncertainty. The ice cream kiosk opened the day we arrived, the owner visibly still finding his summer rhythm, surprised by customers. The mini-supermarket had barbecue charcoal stacked hopefully beside woollen socks, covering every eventuality. Restaurants had tables outside but heaters standing by, ready for Denmark's meteorological indecision.

By our final evening, we had adapted to this rhythm, this not-quite-summer existence. We sat on that terrace again, better prepared with layers and lowered expectations, watching the light do its endless fading act across the pines. The wind still blew, the temperature still dropped, but we stayed longer this time, stubborn and slightly smug in our hard-won seasonal knowledge. Marielyst in late May had not given us the summer we imagined, but something better: summer in potential, summer as possibility, the whole season still to come and us there at its beginning, slightly chilly but entirely present.
