Tuesday, February 9, 2027 · New Orleans, Louisiana (St. Charles Avenue, Canal Street and the French Quarter)
NOAA's 1991–2020 normals for Louis Armstrong New Orleans International Airport, the figures on our New Orleans February guide; Zulu steps off near the morning low. Daylight is for 9 February.
Mardi Gras Day, 9 February 2027: Zulu at 8am, Rex at 10:30am, 10°C / 50°F at dawn and the one day everyone masks.
Dress to stand from dawn. Mardi Gras Day is Tuesday 9 February 2027: Zulu steps off at 8am and Rex at 10:30am, and the walking krewes and costume crowds fill the Quarter and the Marigny in between. NOAA's airport normals give February 19.1°C by afternoon and 9.8°C at night, with about 9 rain days, so Zulu's first floats pass near the day's low. New Orleans & Company describes Mardi Gras as the one day masking is legal for everyone; float riders must mask by law. So the costume goes over warm layers: a purple velvet jacket over a green cable knit, jeans, lug boots for ten hours on the route, a packable shell in case, and a crossbody with room for throws.
Mardi Gras Day is the city in costume from breakfast to dark. Wear purple, green and gold over a sweater, and boots that last from Zulu to Rex.
Mardi Gras Day has a custom rather than a code: costume. New Orleans & Company describes it as the one day masking is legal for everyone in the city, and on the route and in the Quarter most people dress up, in the Carnival colours of purple, green and gold or in a costume of their own design. The route has rules, which NOLA Ready publishes: no glass, no personal items on the right-of-way more than four hours before a parade, and ladders at least six feet back from the curb. The Rex ball that night is the formal end of Carnival and is by invitation; the Rex Organization's protocol calls for costume de rigueur, white tie and tails for men and floor-length gowns, not white, with white gloves for women. For the street, dress up and dress warm.

Mardi Gras Day is costume day, and a velvet jacket is a costume that keeps you warm. Velvet holds heat at the 10°C start of Zulu, and gold sequin lapels catch every float's lights. Purple is the colour of the day.

The warm layer for an 8am start on St. Charles, in Carnival green. A chunky cable knit under the velvet jacket is warm enough at 10°C / 50°F and comes off by the Rex parade.

Ten hours of standing, sitting on curbs and walking to the Quarter. Dark denim takes it and goes under any costume top, and it is warm enough for the morning.

The route is pavement, curb and trodden beads from dawn to dark. A padded lug-sole boot is built for standing all day and grips a sticky street. Laced, it stays on in the crush at Canal Street.

Phone, cash and ID across the body, with both hands free for throws. Olive is a Carnival green, and a flap with gold hardware stays shut in a crowd.

A costume piece you can wear all day without a full costume. A mini top hat on a clip carries purple, green and gold at once and sits above the crowd for the float riders to see.

February has about 9 rain days on NOAA's airport normals, and umbrellas block everyone behind you on a parade route. A packable hooded shell rolls into the crossbody, and mauve stays inside the purple.

A costume or Carnival colours over warm layers, jeans or trousers, and boots you can stand in all day. NOAA's airport normals give February 19°C / 66°F by afternoon and 10°C / 50°F at night, and Zulu rolls at 8am. Carry a small crossbody and a packable shell instead of an umbrella.
Yes. New Orleans & Company describes Mardi Gras Day as the one day masking is legal for everyone, not only float riders, and much of the city costumes, from walking krewes in the Marigny to families on St. Charles. Purple, green and gold are the traditional colours.
On Tuesday 9 February 2027, Zulu steps off at 8am and Rex at 10:30am, followed by truck parades. Check the final routes closer to the day.

It depends on the krewe, but the old-line balls are formal. For the Rex ball on Mardi Gras night, the Rex Organization's protocol asks for costume de rigueur: white tie and tails for men, and floor-length gowns, not white, with white gloves for women. Balls are by invitation.
