Santa Fe dresses for a -8°C–29°C / 18°F–84°F window across the months we cover. Santa Fe runs Pueblo Revival adobe-and-Indian-Market — the heritage 1610 Spanish capital (the oldest US state capital, elevation 6,998 ft / 2,133 m), the heritage Pueblo Revival ordinance since 1957 mandating earth-tone stucco + flat roofs + portales across the historic core. Per NOAA Santa Fe Municipal data, March–May afternoons sit at 14–23°C / 57–73°F with cold -3 to 5°C / 26–41°F mornings; August monsoon afternoons hit 29°C / 84°F (10 rain days, the heritage North American Monsoon); December returns to 6°C / 43°F afternoons + the heritage -8°C / 18°F nights for the Las Posadas + Canyon Road Farolito Walk. Local register: Wheelwright Museum of the American Indian Case Trading Post (the heritage 1937 Mary Cabot Wheelwright museum store), Shiprock Santa Fe (Jed Foutz's contemporary Native-jewelry-and-textile destination on West Palace), Keshi Zuni (the heritage Don Gaspar Avenue Zuni-Pueblo fetish + jewelry cooperative since 1981), Ortega's on the Plaza (the heritage four-generation Santa Fe Plaza turquoise-and-silver authority since 1935), Sorrel Sky Gallery (the heritage contemporary-Western-art Lincoln Avenue), Maya (the heritage East Marcy Street women's-clothing destination, the recognized Santa Fe contemporary-Western boutique).

The neighborhood you sleep in affects what reads as appropriate more than the calendar does. Santa Fe'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 NOAA; 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 NOAA — the national meteorological service for United States. 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 Santa Fe 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 Santa Fe month already changes the silhouette — and the swing between months is much bigger than that. December mornings start at -8°C / 18°F; August afternoons hit 29°C / 84°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: March, May, August, December. 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).
NOAA 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 ("29°C / 84°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. Santa Fe's guide reads like Santa Fe, not like a packing-list aggregator.
