About Copenhagen

May through September offers mild 15-22°C days and near-nightless evenings ideal for cycling to Christiania and dining dockside in Nyhavn. Baltic winds demand a windproof layer even in July, while rainy spells suit visits to Danish Design Museum or smørrebrød lunches. Crowds peak in July, so June or late August means calmer lanes and shorter café waits.
