Pompeii in summer: heat, shade and water

Short answer: arrive at opening time, carry water, take the shorter route and be out before the early afternoon. Pompeii is an open city of stone with almost no shade, and from June to September the heat, not the distance, decides how much of it you see.

Why it is harder than it looks

The streets are dark basalt, the walls are bare stone, and most of the roofs collapsed two thousand years ago. Everything absorbs the sun and gives it back. There are a few pine trees around the edges and almost nothing in the middle of the city, where the Forum, the baths and the best houses are.

When to go

Be at the gate when it opens. The first two hours are the coolest and the quietest, before the coach groups from Naples and Sorrento arrive. Opening hours change with the season, so check the park’s official site the week you travel, but the rule does not change.

Late afternoon is cooler too, but last admission is well before closing time. That leaves room for the shortest route and not much else.

Which route to pick

In July and August, the whole-city route is a bad idea for most people. The houses route is the better summer choice: many of its stops are inside roofed rooms, which is the only real shade in the park. If you want to see more, split the visit in two and take a long break outside the excavations in the middle of the day.

What to carry

• Water, more than you think. There are drinking fountains in the park, but they are spread out, so carry a bottle and refill whenever you pass one.
• A hat and sunscreen. Sunglasses help more than expected: the pale stone reflects a lot of light.
• Closed shoes with a good sole. Sandals on hot, uneven basalt are uncomfortable within an hour.
• Something to eat. There is a café near the Forum, but at midday the queue is long.

Your phone in the heat

Phones overheat in direct sun and dim the screen or stop charging to protect themselves. Inside the excavations, the battery also drains faster than usual, because the phone keeps searching for a signal that is not there. Switch to airplane mode, keep the phone in a bag rather than in your hand, and bring a power bank.

If it is simply too hot

Turning back is a reasonable decision, not a failure. If you feel dizzy or stop sweating, get into the shade, drink, and ask the staff for help.
