When you picture fall in Karachi, you’re looking at a season that slowly shakes off the summer’s grip. Temperatures drift down from the stubborn heat, skies clear up more, and the air feels a lot drier.
Most days, highs slip from the upper 80s °F to the mid-80s °F. Nights start out near 80°F and cool to the low 60s°F as fall goes on.
You’ll spot a sharp drop in humidity and rainfall. Early fall might still throw a few light showers your way, but by the end, dry weather mostly takes over.
Winds lose their edge as weeks pass, and the sky stretches out with long, sunny spells.
With shorter days and cooler evenings, fall feels like a better time to get out and enjoy Karachi. If you’re curious about the city’s seasonal climate patterns or want to plan outdoor adventures, knowing what fall brings can make your trip a lot smoother.
Overview of Fall Weather in Karachi
Fall in Karachi shakes things up—temperatures, humidity, and sky conditions all change. You’ll notice cooler nights, clearer skies, and less rain than in summer, which honestly just makes it nicer to be outside.
Defining Fall Months in Karachi
Karachi’s fall usually runs from September through November. You’ll see the city move from summer’s heat to the mildness of winter during these months.
September still feels pretty warm, with daytime highs in the upper 80s °F (about 31–32°C). By November, highs settle near 85°F (29°C), and nighttime lows can drop to the low 60s °F (16–17°C).
Days get shorter as fall goes on. You lose almost two hours of daylight from early September to late November.
Sunrise shows up later, and sunset sneaks in earlier.
Humidity drops off fast. At first, the air can feel muggy, but by late November, it’s much drier and honestly way more pleasant.
Typical Weather Patterns During Fall
Temperatures keep trending down. Highs go from around 89°F (32°C) in early September to about 85°F (29°C) by late November.
Lows make a bigger leap, dropping from around 80°F (27°C) to about 61°F (16°C).
Rain doesn’t stick around. The chance of a wet day falls from about 7% in September to almost nothing—just 1%—by November. Monthly rainfall drops from nearly 1 inch to almost zero.
Clouds thin out as fall moves along. September might bring some partly cloudy days, but late October often means mostly clear skies.
October 26 is actually one of the clearest days of the year, with clear or partly clear skies nearly 94% of the time.
Winds calm down, too. Average speeds go from over 12 mph in September to about 7 mph by late November. Most breezes come from the west.
Comparing Fall to Other Seasons
Fall feels cooler and less humid than summer. In summer, highs can hit the mid-90s °F (35°C), and the air gets sticky, with stronger winds.
By fall, that heat backs off, humidity drops, and it’s just easier to be outside.
Compared to winter, fall stays warmer and drier. January, the coldest month, can see lows in the mid-50s °F (12–13°C), which is a bigger chill than what you’ll get in fall.
Spring’s another story. March and April heat up quickly into the upper 80s °F (31–32°C), but winds pick up again. Fall, on the other hand, brings calmer weather and a slow, steady cool down.
Rain-wise, fall is way drier than summer. Most of Karachi’s rain comes during monsoon season in July and August. By September, the rain lets up, and the dry stretch keeps going right through winter.
Average Temperatures in Fall
Karachi cools off steadily after summer ends. Daytime highs don’t drop much, but nighttime lows fall pretty sharply, so early and late fall can feel like two different seasons.
You’ll get warm afternoons, cooler evenings, and by the end, milder weather that’s just easier to handle.
Monthly Daytime and Nighttime Temperatures
At the start of fall, daytime highs sit around 89°F (32°C). By late November, they ease down to about 85°F (29°C).
It’s not a huge drop, but it does make outdoor life more comfortable than in summer.
Nights cool off a lot more. Early in fall, lows hover near 80°F (27°C), but by late November, you’re looking at 61°F (16°C). November evenings can feel surprisingly cool after a hot summer.
The gap between day and night temps grows as fall goes on. If you’re heading out, you might want light clothes for the day, but you’ll probably reach for a sweater at night.
Temperature Fluctuations and Extremes
Karachi’s fall temperatures almost never dip below 55°F (13°C) or climb above 99°F (37°C). Sometimes, October throws in a hot day, with highs peaking near 93°F (34°C).
Later in the season, nights can get into the mid-50s. It’s not freezing, but after Karachi’s humid summers, it can feel pretty brisk.
You’ll notice mornings and evenings getting more comfortable as fall goes on. The change is steady, not sudden, but by late November, you’ll definitely feel it.
Historical Temperature Trends
Karachi’s fall weather hasn’t changed much over the years. The city’s desert-leaning climate means daytime highs stay warm, while nighttime lows drop off faster as the season shifts.
Compared to summer, fall gives you a break from the muggy air. September is still warmer and stickier, but by November, things dry out and cool off.
Fall acts as a bridge between the hot, humid monsoon months and the dry, milder winter. You can count on a predictable cooling trend every year.
Rainfall and Precipitation Patterns
Karachi doesn’t get much rain, but you can spot clear seasonal patterns. The city’s dry climate means most months are pretty much rain-free, except for some short bursts during the summer monsoon.
Monthly Rainfall Amounts
Karachi gets about 145–170 mm of rain per year—which is not a lot for a coastal city. Most rain falls between July and September, right when the monsoon season is in full swing.
August is the wettest month, bringing around 50–60 mm of rain. October and November usually see just a trace, often less than 5 mm combined.
Just to lay it out:
| Month | Avg. Rainfall (mm) |
|---|---|
| August | ~57 mm |
| September | ~20 mm |
| October | ~2 mm |
| November | ~1 mm |
You can see how fast rainfall drops once monsoon season ends.
Frequency of Rainy Days
Rainy days are rare in Karachi. The city usually gets only 10 days of measurable rain per year.
Most of these happen in July and August, when heavy downpours can hit without much warning.
In August, you might catch rain on 2 days, and September averages about 1 rainy day. By October and November, it’s almost bone dry—some years, not a single wet day shows up.
When it does rain, showers can get intense. Even if the total rainfall is low, streets can flood quickly.
Impact of Monsoon Residuals
The South Asian monsoon still has some influence into early fall. By September, Karachi can get the odd shower from residual monsoon systems drifting in from the Arabian Sea.
These aren’t as common as in July or August, but they can still dump heavy rain for a short time. You might notice humid air hanging around during this stretch, even if skies look mostly dry.
By October, the monsoon’s pretty much done. Karachi turns dry, with clear skies and barely any rain. That marks the start of the city’s long, dry season, which lasts until the next summer.
Humidity and Wind Conditions in Fall
As fall rolls in, Karachi’s humidity drops sharply, and winds settle down. You’ll feel less stickiness in the air and gentler breezes, making it much nicer to be outside.
Average Humidity Levels
Humidity in Karachi falls quickly during fall. Early September often still feels muggy, with dew points above 70°F, but by late November, the air dries out a lot.
By then, the chance of a humid or oppressive day drops to about 10%, compared with almost 100% at the start of September.
This change matters for daily life. Early fall evenings can still feel sticky, but by mid to late fall, mornings and evenings are way more comfortable for a walk or anything outdoors.
Lower humidity also means less risk of mold indoors and your body cools off more easily. A lot of travelers say late fall is the best time to explore Karachi without the heavy, damp air.
Wind Speed and Direction Trends
Winds shift a lot in fall. Average speeds drop from about 12 mph in early September to around 7 mph by late November. That means calmer conditions compared to the gusty summer winds.
Most of the time, the wind comes from the west and stays pretty steady through fall.
By late November, the air feels calm, and dust in the city can settle down with the lighter winds.
If you’re traveling, lighter winds make ferry rides and beach trips more enjoyable. Residents get a break from strong gusts, too.
Sunshine Hours and Daylight During Fall
Fall in Karachi brings a slow shift from the long, bright days of summer to shorter daylight and softer sunshine. You’ll see clearer skies, fewer clouds, and a steady drop in both sunshine and daylight hours.
Average Daily Sunshine
Sunshine hours drop as fall goes on. In September, Karachi gets close to 8–9 hours of sunshine per day. By November, that’s down to about 7 hours per day.
The drop comes from shorter days and the sun sitting lower in the sky, but skies are clearer than during monsoon months.
September still carries some leftover moisture, but by October and November, clouds are rare.
That makes fall a reliable time for outdoor plans. You’ll get bright days without the harsh glare and heat of midsummer. The mix of moderate sunshine and cooler air makes sightseeing or hanging out by the coast a lot more comfortable.
Length of Daylight Hours
Daylight shortens steadily as fall heads toward winter. Early September gives you about 12 hours and 20 minutes of daylight. By late November, you get just 10 hours and 50 minutes.
It’s a slow change, so you might not notice it right away, but by mid-October, shorter days start to stand out.
Sunrise creeps later, and sunset comes earlier, which can cut into evening plans outdoors.
For planning, just know that sunrise is around 6:00 AM in September but moves to about 6:45 AM by November. Sunset goes from about 6:30 PM in early September to just after 5:30 PM in late November.
This pattern shapes your daily schedule if you’re hoping to make the most of natural light.
Climate Risks and Notable Weather Events
Karachi’s fall season usually brings stable weather. Still, the city faces risks from heavy rains and the occasional tropical system.
These events can disrupt daily life and damage infrastructure. If you aren’t prepared, you might find your travel plans suddenly upended.
Unusual Rainfall and Flooding
Rain in Karachi doesn’t happen often, but when it does, it usually arrives in short, intense bursts. In the fall, leftover monsoon systems from late summer sometimes bring heavy downpours into September.
These rains can cause localized flooding, especially in low-lying neighborhoods or spots with bad drainage.
Flooding keeps coming back as a problem because the city’s drainage network just can’t handle sudden rainfall. Streets flood fast, and standing water can stick around for days.
Traffic slows to a crawl, flights get delayed, and both business and leisure plans take a hit.
Even moderate rainfall can overwhelm Karachi’s electricity systems. Power outages happen often during storms, and in some districts, the lights might stay out for hours.
Travelers should plan for delays and check conditions before heading out.
| Risk Factor | Impact on Karachi |
|---|---|
| Heavy rain | Street flooding, traffic jams |
| Poor drainage | Waterlogging in neighborhoods |
| Power outages | Service disruptions during storms |
Cyclone and Storm Occurrences
Karachi sits along the Arabian Sea, so tropical cyclones are a real threat. Direct hits don’t happen often, but nearby storms still bring strong winds, high waves, and heavy rain.
The fall season sometimes brings late tropical systems that develop in the Arabian Sea.
When a cyclone gets close, authorities issue warnings about coastal flooding and tell people to stay indoors. Strong winds can damage trees, billboards, and any weak structures.
Even if the storm doesn’t make landfall, rough seas can disrupt port operations and fishing trips.
Visitors might face air travel issues too, since flights get delayed or canceled during storm alerts. If you’re traveling in September or October, keep an eye on local weather updates—those months are prime time for late-season storms.
Key concerns include:
- High winds damaging property
- Coastal flooding in vulnerable zones
- Transport disruptions on land, sea, and air
Practical Tips for Experiencing Fall in Karachi
Fall in Karachi brings slightly cooler temperatures. You’ll notice lower humidity and less rainfall compared to the summer.
These conditions make outdoor activities more comfortable. You can explore the city with lighter travel preparations.
Best Activities for Fall Weather
The beaches along the Arabian Sea are great this time of year. The weather stays warm but isn’t as sticky as summer, so Clifton Beach and Sandspit turn into popular spots for evening walks or picnics.
Calmer winds make boat rides and fishing trips a lot more pleasant.
Museums and cultural sites like the Mohatta Palace or the Quaid-e-Azam Mausoleum are good picks if the midday sun feels a bit too much.
Outdoor markets, especially Empress Market, are easier to wander through in the cooler mornings or evenings.
If you’re into nature, try Karachi’s parks like Bagh Ibne Qasim or Safari Park. Fall’s reduced cloud cover often gives you clear skies, making evenings just right for outdoor dining or rooftop gatherings.
Sports like cricket and football pop up everywhere during this season, since the weather doesn’t sap your energy as much.
Travel and Packing Recommendations
Pack light, breathable clothing like cotton shirts, dresses, and trousers. Daytime highs often reach the mid-80s °F (around 29–30°C), so you’ll want to stay cool in the heat.
Evenings feel a bit cooler, so toss a light sweater or jacket into your bag.
Pick footwear that’s practical for walking around markets or heading out to the coast. I’d go with sandals or sneakers.
You probably won’t need heavy rain gear since fall rainfall barely happens, but sunglasses and sunscreen come in handy thanks to Karachi’s strong sun.
For getting around, taxis and ride-hailing apps usually work well. Still, traffic jams are a thing.
Try planning outings in the morning or later in the evening to dodge the worst congestion and the hottest hours. Don’t forget to carry bottled water, since humidity can still sneak up on you in early fall.
