The Washington DC packing calendar
Washington DC's year peaks at 32°C in July and bottoms out around -1°C in January nights — a 26°C swing between its warmest and coldest daytime months. That range is wide enough that Washington DC effectively has two separate wardrobes — pack for the month, not the city.
Rain concentrates in March, April, May, July, August — the Washington DC months where the water-ready layer stops being optional. For the lightest possible bag, aim for October, November — dry, mild, and the easiest Washington DC packing of the year.
For calibration: Washington DC runs 3°C warmer than Philadelphia in January and 1°C warmer in July. Against Minneapolis, the differences are 11°C in January and 2°C in July. If you already own a capsule for one of those cities, the Washington DC version is an edit, not a rebuild.
