New Orleans dresses for a 12°C–33°C / 54°F–91°F window across the months we cover. New Orleans dresses for heat, humidity, and festivals. Jazz Fest weekends in late April–early May are a city-wide dress code of cotton and linen; the French Quarter in summer is bright colors, sundresses, and shoes you can walk on Bourbon Street in. The climate punishes synthetics on the body but rewards quick-dry nylon for bags and rain jackets. Afternoon thunderstorms are frequent June–August; packable rain gear earns its weight.
Across the 6 months we cover: morning lows from 12°C / 54°F (November) to afternoon highs of 33°C / 91°F (July).

The neighborhood you sleep in affects what reads as appropriate more than the calendar does. New Orleans'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 USA. Daily highs and lows, rain days, and daylight hours are 1991–2020 normals, read at the Lakefront Airport station — the international standard, refreshed every decade. Capsule pieces and what-to-avoid notes are stress-tested against New Orleans 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 New Orleans month already changes the silhouette — and the swing between months is much bigger than that. November mornings start at 12°C / 54°F; July afternoons hit 33°C / 91°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.
6 so far: May, June, July, August, October, November. 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 NOAA figures cited on every New Orleans leaf are 1991–2020 normals, read at the Lakefront Airport station — the international standard, refreshed every decade. We restate the numbers as raw averages on the leaf pages ("33°C / 91°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. New Orleans's guide reads like New Orleans, not like a packing-list aggregator.
