April - September
While Memphis is a year-round destination for travelers, spring and summer are its busiest times. Spring is the most pleasant, weather-wise. The skies are blue, temperatures hover in the 70s, and the streets bloom with azaleas, hydrangeas and magnolias. Come summer, the mercury rises and the city can be uncomfortably hot. The week leading up to Elvis's death date of Aug. 16 is one of the city's most crowded times, as thousands of King-worshippers flood the city for prayer vigils, swap meets and other activities. May is also busy due to the popular Memphis in May festival, which celebrates Memphis music, barbecue and art. Hotel rates don't tend to change much from high to low season, but rates are often lower on weekends due to a downtick in business travel.
December - February
Winter is Memphis's off-season. The weather can be gray and chilly, though rarely uncomfortably cold. Significant amounts of snow are uncommon. The lines are shorter at Graceland, Beale Street is a little less wild, and the barbecue joints less packed. If you enjoy a lower-key pace, this is a fine time to visit the city. Just bring a jacket and an umbrella.
October - November
If Memphis had a genuine shoulder season, fall would be it. The weather is nicer than winter, with more sunny days than not. Crowds are thinner than in summer, but not as thin as winter. If you're willing to brave slightly unpredictable weather, fall is just as nice a time as any to visit Memphis.
