New Orleans weather by month

Mild winters, a warm and festival-packed spring, and long, steamy summers. The best months for walking around are roughly November to April; Carnival usually lands in February or early March, when highs are around 68°F.

Hurricane season runs from 1 June to 30 November (NOAA National Hurricane Center). Most storms never reach New Orleans, but if you travel then, watch the NHC outlook in the week before you go.

Dew point is a better guide to how sticky it feels than relative humidity: below 10°C (50°F) is dry, 16–18°C (61–64°F) humid, above 21°C (70°F) oppressive.
