UK · Climate data from the UK Met Office
Edinburgh dresses for a 6°C–19°C / 43°F–66°F window across the months we cover. Edinburgh runs Scottish heritage — Pringle of Scotland (Hawick-founded 1815, the heritage Scottish cashmere with the Argyle pattern), Mackintosh (Glasgow-founded 1823, the heritage rubberized waterproof — the original raincoat), Harris Tweed (Outer Hebrides handwoven wool since 1846, Orb-mark certified — protected by the Harris Tweed Act 1993), Johnstons of Elgin (Scottish cashmere since 1797), Walker Slater (Edinburgh tweed tailoring), Holland Esquire (Edinburgh tailoring). The Royal Mile cobble + Old Town stairs need structured leather soles. Edinburgh Festival Fringe (the world's largest arts festival) runs all of August — 3,000+ shows, 2.5 million tickets; Edinburgh International Festival, Royal Edinburgh Military Tattoo run concurrently. Hotel rates 3-5x higher in August; book 6-12 months ahead.
Across the 4 months we cover: morning lows from 6°C / 43°F (May) to afternoon highs of 19°C / 66°F (July).

The neighborhood you sleep in affects what reads as appropriate more than the calendar does. Edinburgh'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 the UK Met Office; 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 the UK Met Office — the national meteorological service for UK. 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 Edinburgh 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 Edinburgh month already changes the silhouette — and the swing between months is much bigger than that. May mornings start at 6°C / 43°F; July afternoons hit 19°C / 66°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.
4 so far: May, June, July, August. We ship climate-and-event-distinct months only — adjacent months that share more than 60% of the same capsule pieces don't get separate pages, because near-identical leaves erode the credibility of every other page on the site. The full coverage plan is in our internal CLAUDE.md (the editorial brief governs every page that ships).
the UK Met Office 1991-2020 normals are the version cited on every leaf — the international meteorological standard, updated by every national service every decade. We restate the numbers as raw averages on the leaf pages ("19°C / 66°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.
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. Edinburgh's guide reads like Edinburgh, not like a packing-list aggregator.
