Tourists are drawn to the southern Italian city of Naples for its museums and monuments, cuisine, timeless cityscape, and its proximity to the archaeological site of Pompeii. Naples is a year-round destination, though many prefer to visit in the hot and humid summer months to take advantage of nearby beaches, including those of the Amalfi Coast.

Fall and spring see mild temperatures and moderate rainfall, while winters see cool, but not cold temperatures and a lot of rain (4 to 5 inches each month). Summer is also the driest and busiest season so you should expect higher hotel prices and lower room availability, as well as crowded streets, piazzas, and tourist attractions.

Spring in Naples

Like most other parts of the world, spring is a transitional season in Naples. March starts off cool and rainy but by May, people have traded jackets and umbrellas for sun hats and sunscreen. Naples will be crowded around Easter Week, which falls in either March or April. Otherwise, March is less busy, with crowds building in tandem with rising temperatures through May. A sunny spring day is a great one for walking around the city and taking day trips to Pompeii or Vesuvius.

What to pack: Pack lightweight pants and both long- and short-sleeved shirts and T-shirts. For chilly nights, a lightweight jacket and a medium-weight scarf should suffice. Remember to pack an umbrella. On Naples' congested streets, closed, sturdy shoes are recommended.

Average Temperatures and Rainfall by Month:

  • March: 62 F / 45 F (17 C / 7 C)
  • April: 67 F / 50 F (19 C / 10 C)
  • May: 75 F / 58 F (24 C / 14 C)

Summer in Naples

Summers in Naples are hot and humid. Despite relatively low rainfall of 1 to 2 inches per month from June to August, Naples has a subtropical summer climate. Temperatures average in the high 80s but can go much higher, occasionally topping out at 100 degrees F (38 C) and a sudden, brief thunderstorm is not unheard of. It's crowded here in the summertime, and in the evenings, Neapolitans pour out of their small apartments in search of a cool breeze. So expect to see streets and piazzas crowded with tourists and locals alike enjoying the passeggiata (evening stroll). If you're visiting in the summer and there are museums you're set on seeing, consider booking a time slot in advance to avoid disappointment.

What to pack: Shorts, lightweight slacks, and short-sleeved shirts should be suitcase staples. Men should consider collared shirts for dinners out, and women might want to pack sundresses, lightweight skirts, and blouses. For the occasional cool evening, bring a lightweight jacket or scarf. Remember that in order to enter churches, shoulders, cleavage, knees must be covered.

Average Temperatures and Rainfall by Month:

  • June: 82 F / 64 F (28 C / 18 C)
  • July: 87 F / 69 F (30 C / 21 C)
  • August: 88 F / 70 F (31 C / 21 C)

Fall in Naples

Fall rolls in gently in Naples, as early September weather differs little from that of August. By mid-month, air and sea temperatures will start to cool off—though you can still swim in the Bay of Naples in late September. There's more rain in September and by November, more than six inches a month fall on the city. But if you can abide by rainy days, fall is a great season to visit, both for cooler weather and fewer crowds.

What to pack: Bring lightweight slacks, lightweight long- and short-sleeved shirts, and tailored shorts. For September, a lightweight jacket and scarf will probably suffice (and might be unnecessary) but by October and November, you'll want a waterproof jacket, a scarf, and, of course, an umbrella.

Average Temperatures by Month:

  • September: 81 F / 63 F (27 C / 17 C)
  • October: 74 F / 57 F (23 C / 14 C)
  • November: 65 F / 49 F (18 C / 9 C)

Winter in Naples

Winter is a great season for visitors who want to concentrate on seeing the city's many museums, and exploring its (rainy) streets largely free of tourists. December is second only to November for monthly rainfall—nearly five inches fall on the city on average. City hotels will be open, though some hotels and restaurants might opt to close for a few weeks at Christmas and New Year's—be sure to book well in advance if you plan to visit over these holidays. Temperatures hover around 50 degrees F (10 degrees C) from December through February, and days are short, with just 9 to 10 hours of daylight.

What to pack: While temperatures will probably be mild, they can feel a lot colder on a damp, overcast day. Pack a medium-weight coat, and a scarf and a hat just in case. This is the season to have jeans, slacks, long-sleeved shirts, and sweaters in your suitcase. Also, bring an umbrella and a waterproof jacket.

Average Temperatures by Month:

  • December: 58 F / 43 F ( 14 C / 6 C)
  • January: 57 F / 41 F (14 C / 5 C)
  • February: 57 F / 41 F (14 C / 5 C)
