February 5–13, 2027 · Grupo Especial February 7, 8 and 9 · Sambódromo da Marquês de Sapucaí and streets across Rio de Janeiro
NOAA NCEI's record for Santos Dumont airport, February averages, the figures on our Rio February guide; the Sambódromo nights sit near the 24°C low. Daylight is for 8 February.
Rio Carnival 2027: Grupo Especial on 7, 8 and 9 February, four schools a night, 24°C / 75°F after dark and 31°C by day.
Dress for heat that does not break at night. NOAA NCEI's record for Santos Dumont gives February 31.2°C by day and 24.4°C at night, the hottest month on that record, with thunder on about 6 days. Carnival runs from the Série Ouro on 5 and 6 February to the Grupo Especial on 7, 8 and 9 February, four schools a night, each parading for over an hour, and the champions' parade on the 13th. That is a night in the stands until the early hours, still near 24°C. By day the street blocos take over, as they have since Riotur's street carnival opened on 16 January. The city health department's advice sets the base: high-SPF sunscreen, a cap or hat, light clothes and closed, comfortable shoes. Add sequins.
Carnival asks for two outfits: one for a bloco under the noon sun, one for a Sambódromo seat at 24°C after midnight. Sequins cover both if your shoes can walk.
The Sambódromo has no dress code for the arquibancadas and frisas; a fantasia, a Carnival costume, is as welcome in the stands as shorts and a tank. Camarotes, the private boxes, set their own rules, and most hand guests a shirt they must wear inside, so check yours. Expect bag checks at the gates, and check LIESA's list for what you may bring in 2027. On the street, blocos have their own traditions, from Cordão da Bola Preta's black and white spots to themed costumes, and a fantasia is the norm. The line to hold: skip costumes that caricature a people or a religion, including Indigenous headdresses and Afro-Brazilian religious dress worn as fancy dress. Glass is taken off revellers at the blocos, so carry cans or plastic.

Carnival is the one week when a sequin top is daywear. Cropped and strapped, it stays cool in a bloco at 31°C and catches the Sambódromo lights at midnight. Fuchsia and gold read from the top of the stands.

Shorts are what you want for hours of dancing in the street and sitting on concrete tiers. A high waist sits under a belt bag, and gold lamé makes them part of the costume rather than a pair of shorts.

The city health department asks for closed, comfortable shoes at Carnaval, and in a bloco crowd you will be stepped on. Mesh runners breathe at 31°C, dry after a storm, and lace tight for a night of dancing.

Phone, card and cash, zipped and worn in front where you can feel it in a crowd. A belt bag leaves both hands free and clears a Sambódromo bag check.

A hat is on the health department's list for daytime blocos under the February sun. Open crochet straw lets heat out and crushes into the belt bag for the Sambódromo at night.

The menswear version of a fantasia. A loose viscose camp shirt moves air at 24°C in a packed stand, and fuchsia and gold palms match a partner in sequins.

Feathers are Carnival's signature, and a headband carries them without a full costume. It sits on your head in a crowd, where a held prop would be lost, and it swaps for the straw hat at sunset.
Sequin bralette under an open camp shirt · gold shorts · mesh runners · straw hat · belt bag. A bloco from mid-morning, SPF 50 reapplied, cans not glass.
Sequin bralette · gold shorts · feather headband · runners · belt bag. The Sambódromo from about 9pm, four schools, near 24°C / 75°F into the early hours.
A suggested look — fuchsia and gold sequin bralette, gold metallic shorts, fuchsia feather headband, grey mesh runners, tan leather belt bag worn across the body.
Something light and festive, sequins or colour, with closed, breathable shoes, a hat by day and a small bag worn in front. NOAA NCEI's Santos Dumont record gives February 31°C / 88°F by day and 24°C / 75°F at night, and the city health department's Carnaval advice is sunscreen of SPF 50 or higher, a hat, light clothes and closed shoes.
LIESA's Grupo Especial parades at the Sambódromo on Sunday 7, Monday 8 and Tuesday 9 February 2027, four schools a night, and the champions return on Saturday 13 February. The Série Ouro parades on 5 and 6 February. Ash Wednesday is 10 February.
Not in the arquibancadas or frisas, where costumes, shorts and tank tops are all normal. Camarotes set their own rules, and most require the shirt they give you. Expect a bag check at the gates, and check LIESA's list of permitted items before you go.
Yes, it is the norm. Blocos are street parties, and many have themes or traditions, such as Cordão da Bola Preta's black-and-white spots. Wear closed shoes and light fabrics, and skip costumes that caricature a people or a religion.
Very hot, even at night. NOAA NCEI's record for Santos Dumont airport gives February an average high of 31.2°C / 88°F and a low of 24.4°C / 76°F, the hottest month on that record, with about 20 days above 30°C and thunder on about 6. Daylight is about 12 hours 59 minutes on 8 February.
