Germany · Climate data from Deutscher Wetterdienst
Berlin dresses for a 7°C–25°C / 45°F–77°F window across the months we cover. Berlin reads understated and dark — Helmut Lang's archive over Gucci's monogram, every time. The minimal-techno-leather palette holds across May-August: a black leather jacket layers over fine-knit sweaters in May, rotates out for cotton tees and linen overshirts by August, but the register stays quiet. Mitte runs gallery-luxury (Acne Studios on Münzstraße, Andreas Murkudis off Tiergarten), Kreuzberg runs Turkish-and-techno, Prenzlauer Berg runs café-creative, Friedrichshain runs club-residential. Berghain's documented dress code (layered black, no logos, no tour-group energy) sets the tone for the rest of the city's nightlife. Cobblestones in Mitte and Prenzlauer Berg punish thin soles — Common Projects, Veja, or Sambas read local; stilettos do not.
Across the 5 months we cover: morning lows from 7°C / 45°F (October) to afternoon highs of 25°C / 77°F (July).
What to wear in Berlin in May: DWD data (19°C / 66°F, 9°C / 48°F mornings, 11 rain days) — the Mitte-to-Kreuzberg layered-black capsule for café season.
What to wear in Berlin in June: DWD data (23°C / 73°F, 13°C / 55°F mornings, 10 rain days) — Karneval der Kulturen and Tempelhofer Feld picnics in a layered-black capsule.
What to wear in Berlin in July: DWD data (25°C / 77°F, 14°C / 57°F mornings, 13 rain days) — Berlin Fashion Week and Christopher Street Day in the peak-summer Mitte capsule.
What to wear in Berlin in August: DWD data (24°C / 75°F, 14°C / 57°F mornings, 13 rain days) — late summer, Tempelhofer Feld evenings, and the Berlin understated capsule.
What to wear in Berlin in October: NOAA data from the Tempelhof station (14°C / 57°F days, 7°C / 45°F nights, 12 rain days), and the all-black layered capsule.
The neighborhood you sleep in affects what reads as appropriate more than the calendar does. Berlin's style scene anchors on the districts below — each leaf page calls out the local register (smart-casual, undone, technical, party) so the capsule maps to the streets you'll actually walk on.
Every leaf page on this hub is built from four data layers: climate normals from Deutscher Wetterdienst; named-authority etiquette and style references (Vogue, Condé Nast Traveler, Business of Fashion, the relevant local press); resident write-ups and traveler-forum reports for the failure modes tourists get wrong; and the editorial avatar pool that visualises each capsule on a person rather than a moodboard. Every DO names a reason. Every DON'T names a failure mode. We retest before each seasonal refresh — the editorial-modified date at the bottom of each leaf is the receipt.
Climate numbers come from Deutscher Wetterdienst — the national meteorological service for Germany. Daily highs and lows, rain days, and daylight hours are 1991–2020 normals — the international standard, refreshed every decade. Capsule pieces and what-to-avoid notes are stress-tested against Berlin resident write-ups, named-stylist sources where the city has a documented uniform (Vogue Paris under Emmanuelle Alt for Paris, Vogue Japan and i-D Tokyo coverage for Tokyo, NYMag's The Cut for New York), and the failure modes locals actually flag in city forums and traveler reports.
Because the morning-low to afternoon-high swing inside one Berlin month already changes the silhouette — and the swing between months is much bigger than that. October mornings start at 7°C / 45°F; July afternoons hit 25°C / 77°F. A single packing list that tries to span both ends up wrong at both. Each month here is a different capsule, calibrated to the climate band that actually shows up on the ground.
5 so far: May, June, July, August, October. There is no cap on months per city — we are working through the calendar, and a month is only worth publishing when it has its own thesis, so no two adjacent months here share a capsule piece or an illustration. Months we haven't written yet are gaps in the schedule, not judgments that the month isn't worth covering.
The Deutscher Wetterdienst figures cited on every Berlin leaf are 1991–2020 normals — the international standard, refreshed every decade. We restate the numbers as raw averages on the leaf pages ("25°C / 77°F afternoons") rather than the year range, so the figures don't read as stale. The next normals refresh covers 2001-2030 and lands in 2031 — we'll bump every page when it does. One month on this city carries its own provenance — see `provenance` on the entry in data/seo/months/berlin.ts. DWD publishes normals only through a search form, so no station is recorded for the remaining months.
Editorial rule, enforced in CI: every DO line names a specific reason ("merino sinks under a trench so a damp morning doesn't show through your knit"); every DON'T names a specific failure mode ("suede stains the first time light drizzle catches it"). We ban "timeless," "elevate your style," "must-have," and "effortless" — they're the giveaway phrases of generic AI fashion writing. If a sentence could open any city's guide, it gets cut. Berlin's guide reads like Berlin, not like a packing-list aggregator.
