By late June, Düsseldorf keeps a particular hour. The sun stays high for a long time, the evenings stretch out, and around half past nine a soft golden light still rests on the Rhine. It is the time of year when a walk does not want to end and the city by the water shows its calmest face.

I like to begin in the late afternoon on the Rheinuferpromenade, once the strongest heat has eased and a cool draught rises off the river. The path is wide and open, the boats pass slowly, and the steps by the water gradually fill with people who are simply watching the evening arrive. There is no need to plan anything; the long light sets the pace.

From the promenade I drift into Carlstadt, where the narrow streets turn cooler and quieter at dusk. A glass outside a small place, a glance into a shop window, then on toward the Altstadt, which in high summer only truly wakes up late. Among the old façades, the day still hangs in the warm air.

For the last stretch I often head into the Hofgarten. Under the tall trees the warmth of the day gathers, the park softens, and the paths lie almost empty. It is the quiet counterpart to the busy promenade, a green space where the long summer evening fades very slowly.

What I enjoy most in late June is the generosity of the light. Here in the north the days are long, and the dusk draws itself out as though it were in no hurry. After dinner you can still walk down to the river a second time without darkness falling, and the city gives you these extra hours as a matter of course.

High summer in Düsseldorf, for me, is not about a full programme but about time. The bright evenings give hours you do not usually have, and the city by the Rhine gives them a beautiful frame. You walk a little further, you stay a little longer, and the day only takes its leave once you are ready.
