The Deep South is at its best between March and May, when the weather is warm and sunny, and the nights are pleasantly cool.

By June, heat and humidity become a consideration, and travel over July and August is best avoided unless you’re comfortable in the sticky heat of a southern summer.

By September and October, temperatures and humidity levels have dropped from their summer highs and, in the Great Smoky Mountains, the turning trees provide a dramatic fall display. There is a risk of occasional hurricanes, particularly along the coast, from June to November.

Month-by-month guide for travelling in the Deep South

Longwood, Natchez

Visiting the Deep South in January - March

Winter is relatively mild in the Deep South, with balmy temperatures along the Gulf Coast. There is increased rainfall across the area, while snow in the mountains can close some of the higher passes. New Orleans pulls in the crowds for Mardi Gras, when the city gets very busy and prices go up, but this vibrant celebration is well worth the additional expense.

Events & Festivals

  • Mardi Gras, New Orleans’ biggest festival, culminates on Shrove Tuesday (usually in February), with the largest and liveliest parades and street parties in the preceding few days. Read more
  • The Spring Pilgrimage in Natchez, Mississippi, sees historic antebellum homes open to the public from mid-March to mid-April. Read more
Charleston Magnolia Plantation and Gardens

Visiting the Deep South in April - May

Spring in the Deep South is an ideal time to visit, when the climate brings warm, sunny days and cooler nights. By mid-April, the gardens at Magnolia Plantation outside Charleston are in bloom, most of the roads and trails in the Great Smoky Mountains have reopened, and all the heritage sites are up and running.

Events & Festivals

  • The New Orleans Jazz & Heritage Festival (late April to early May) celebrates the music and culture of the region, from blues, R&B and gospel to country, bluegrass and Cajun. Read more
  • The Spring Pilgrimage in Natchez, Mississippi, sees historic antebellum homes open to the public from mid-March to mid-April. Read more
Jekyll Island

Visiting the Deep South in June - August

By June, temperatures across the south are noticeably higher. By July, it’s hot and sticky with averages of 30°C (86°F) and highs of 40°C (104°F). Coupled with high humidity levels, it can feel unbearably hot. To cope with the heat, you could follow the locals and head for the coast to relax on Jekyll Island off Georgia or see nesting sea turtles on the South Carolina beaches.

Events & Festivals

  • Elvis Week, each August in Memphis, commemorates the anniversary of the King’s death with panel discussions, live music and the Ultimate Elvis Tribute Artist Contest. Read more
  • The CMA Music Festival in Nashville takes place in early June each year and features four days of concerts in the home of country music. Read more
Great Smoky Mountains National Park

Visiting the Deep South in September - October

September sees a welcome decrease in temperature and humidity, making the Deep South’s fall another good time to visit (though the chance of hurricanes reaches its peak along the coast between August and October). The turning leaves provide a fiery backdrop to the Natchez Trace Parkway, an old trade route from Nashville to Natchez, and the Great Smoky Mountains are particularly scenic at this time of year.

Events & Festivals

  • During the three-week Fall Pilgrimage (late September into early October) in Natchez, Mississippi, costumed guides will show you around the city’s historic homes and offer an insight into their original owners. Read more
  • New Orleans’ Voodoo Music + Arts Experience is a festival of music, concerts and costumed street parties, which happens around Hallowe’en. Read more
Jackson Square in New Orleans

Visiting the Deep South in November - December

Although temperatures fall considerably in winter, the weather is still generally mild in the south with higher rainfall and only rare snowfall. Cities take on a magical appearance around Christmas, with the lights at Nashville’s Gaylord Opryland Hotel a major attraction. It’s also a great time to take in the special events at the Ryman Auditorium in Nashville, which hosted the Grand Ole Opry for more than 30 years.

Events & Festivals

  • New Year’s Eve is another big party night in New Orleans, with fireworks, plenty of live music and a buzzing bar scene. Read more
