There's something about Washington DC in late March when the cherry blossoms peak that turns the political city into something tender. I stood at the Tidal Basin one spring as 3,000 trees bloomed pink against the Jefferson Memorial — the data says peak bloom is usually the last week of March to first week of April, around 15°C. Summer (June-August) is famously brutal: 30°C with 70% humidity, the kind that makes the National Mall feel like a sauna. October is DC's secret weapon: 18°C, golden leaves along the Mall, and the cultural season reopening. Winter is quieter and the museums are empty — a trade-off worth making.
