Karachi sits on the coast, and its summers are hot and humid. The sea breeze helps in the evening, but in the middle of the day the heat can be tiring even for people who live here. If you are visiting between late spring and early autumn, a little planning will keep you comfortable, healthy and able to enjoy the city.

This guide covers what to expect, how to organise your day, how to choose a room that is easy to live in during hot weather, and what to do if the heat becomes a problem.

What to expect

Summer in Karachi means high temperatures and high humidity, which makes it feel hotter than the number on the thermometer. There can be heatwaves, when temperatures stay high for several days, and the monsoon season can bring heavy rain, which sometimes floods roads and slows traffic. Power cuts can happen in many Pakistani cities, so it is wise to plan for them. If you can choose your travel dates, the cooler months from about November to February are the most comfortable, but with good planning summer visits can go well too.

Plan your day around the heat

  • Morning (early): the best time for outdoor sights, walking and photography.
  • Midday: rest indoors, have lunch, and spend time in an air-conditioned place such as a museum, mall, cafe or your room.
  • Late afternoon and evening: go back out when the sun is lower. The seafront is popular at this time of day.

Do not plan too many outdoor stops in one day. One or two well-chosen places are better than five in the sun.

Staying healthy in the heat

Drink more than you think you need

Carry water with you and drink regularly, even if you do not feel thirsty. Use bottled or properly filtered water. Fresh juices and lemon drinks are popular, but choose clean places, and be careful with ice if you are not sure of its source.

Dress for the weather

Wear loose, light-coloured cotton clothes that cover your arms and legs, a hat or cap, sunglasses and comfortable shoes. Use sunscreen on exposed skin, and carry a light scarf to protect your head and neck.

Eat sensibly

Heat spoils food faster, so choose busy places where food is freshly cooked, and avoid food that has been standing in the sun. Smaller, lighter meals are easier to manage in hot weather.

Know the warning signs

Headache, dizziness, nausea, heavy sweating followed by a dry, hot feeling, or confusion can be signs of heat exhaustion or heatstroke. If someone in your group has these signs, move them to a cool, shaded place, loosen their clothing, give small sips of water if they are alert, cool them with wet cloths and get medical help quickly. Heatstroke is an emergency.

Choosing a room for hot weather

In summer, the room matters more than usual. Before you book, ask:

  • Does the room have air conditioning, and does it work well? Ask whether it is a split unit or a window unit, and whether you control it.
  • Is there backup power, so the air conditioning and lights keep working during an outage?
  • Is there hot and cold running water, and does it work at all hours?
  • Is the room on a high floor or in direct afternoon sun, which can make it hotter?
  • Is there a lift? Stairs are tiring in the heat, especially with luggage, children or older relatives. Hotel Crown Plaza in Gulistan-e-Johar, for example, has a lift.
  • Is parking covered or shaded if you travel by car?

Travelling with children and older relatives

Children and older people feel the heat more quickly. Plan shorter outings, build in rest breaks, carry water and snacks, and choose air-conditioned places for the hottest part of the day. Never leave a child or an older person in a parked car, even for a moment. A room with reliable cooling and an easy way to reach it, such as a lift or a ground-floor room, makes the stay much easier.

Getting around in the heat

  • Choose air-conditioned cars or ride-hailing options when you can.
  • Avoid walking long distances at midday.
  • Carry a power bank, because a phone battery runs down faster in the heat.
  • During monsoon rain, expect delays and avoid low-lying roads. Leave extra time before flights.

A short packing list

  • Light cotton clothes and a spare set.
  • Hat or cap, sunglasses and sunscreen.
  • A reusable water bottle.
  • Oral rehydration salts, a small first-aid kit and any medicine you take regularly.
  • A light umbrella, useful against sun and rain.
  • A power bank and a small torch.
