> Karachi's 'second summer' is here. Tuesday's high was 38.7°C with 43% humidity, and a high-pressure system that has choked the sea breeze could push it past 40°C.

**Karachi weather today: the city recorded a high of 38.7°C on Tuesday 13 October, and a Met Office official has warned that the mercury could reach 40°C if the trend holds.** Humidity was 43%, low by Karachi standards but enough to make the afternoon feel heavy, [Dawn reported](https://www.dawn.com/news/2036985/karachi-swelters-as-mercury-soars-to-387c) on Wednesday.

## Why Karachi is this hot in mid-October

The official told Dawn that a high-pressure area in the upper atmosphere has weakened the winds over the city. When the sea breeze from the south-west drops, Karachi loses its natural air conditioning and daytime temperatures climb quickly, even late in the year.

This is not unusual. October is often called Karachi's "second summer": the monsoon has gone, the sea breeze is unreliable, and the cool northerly winds of winter have not yet arrived. Hot spells in the high 30s are a feature of most Octobers.

## What 38.7°C means for you

- **Heat and water.** Drink water through the day, not only when thirsty, and keep children, older relatives and outdoor workers out of the direct sun between noon and 4pm.
- **Power use.** Air conditioners will run longer this week, and extra units can push a bill into a higher slab. Work out your own figure with our [AC running cost calculator](/tools/utilities/ac-running-cost-calculator) and check what the extra units do to your slab with the [electricity bill calculator](/tools/utilities/electricity-bill-calculator).
- **Load management.** K-Electric has ended its temporary night-time load management after RLNG supply resumed, so hotter nights should not mean extra cuts on that account. Our [K-Electric story](/news/pakistan/k-electric-warns-of-night-time-load-management-in-karachi-as-rlng-shortage-hits) has the details, and the [KE duplicate bill guide](/guides/utilities/k-electric-bill-check-online) shows how to check what you owe.

## How long will it last?

The Met Office has not given an end date. Its warning is conditional: 40°C is possible if the current pattern continues. Relief usually comes when the sea breeze returns, which can happen within days once the high-pressure system shifts. Check [today's Karachi weather and forecast](/weather/karachi) before planning outdoor work or travel in the afternoon.

We will update this page if the Met Office issues a formal heatwave advisory for Karachi or Sindh.
