When you think about fall in Tripoli, you’ll notice a real shift from those hot summer days to weather that’s a lot more comfortable. Average high temperatures drop from the low 90s °F in early September to around 70°F by late November. Nights cool off too, going from the mid-70s °F to the mid-50s °F.
This steady change makes fall one of the best times to be in the city. There’s something relaxing about the milder air.
You’ll spot other patterns too. Rain starts to show up more as fall rolls on, and cloud cover creeps in. Humidity drops, so the air feels drier and more pleasant.
Sunshine hours get shorter pretty fast, but you still get plenty of bright days, especially in September and early October.
If you’re thinking of visiting, you’ll enjoy mild daytime warmth, cool evenings, and that nice dip in humidity. These conditions really make exploring Tripoli’s historic sites and coastal views a lot more enjoyable.
Overview of Fall Climate in Tripoli
Fall in Tripoli brings a steady drop in temperatures and shorter daylight hours. You’ll feel a clear shift from the dry summer toward a cooler, wetter season.
Cloud cover increases, winds pick up, and the Mediterranean water nearby gets cooler as the weeks pass.
Seasonal Weather Patterns
During fall, daily high temperatures in Tripoli start around 33 °C (91 °F) in early September and fall to about 21 °C (70 °F) by late November.
Nighttime lows drop from 23 °C (73 °F) to about 13 °C (55 °F). That’s a pretty big difference.
Rainfall picks up as fall goes on. September is usually dry, but by November, you might see about 31 mm of rain in a month. The chance of a wet day rises from 1% to 13%.
Humidity changes fast. Early fall can feel muggy, with dew points above 21 °C, but by late November, it’s much drier. Winds get stronger too, moving from 15.5 km/h to nearly 20 km/h.
Clouds take over more of the sky, going from mostly clear in September to about a third of days being overcast by November. Late fall just feels cooler and less sunny compared to early September.
Tripoli Climate Classification
Tripoli falls under a hot semi‑arid climate (BSh) in the Köppen system. That means you get long, dry summers with almost no rain, and winters that are mild but wetter.
Fall sits right in the middle of these two extremes. Rainfall is limited compared to Mediterranean places further north, but you’ll definitely notice more rain in October and November.
The city gets about 350 mm (14 inches) of rain each year, and most of it falls in the cooler months.
The sea really helps keep temperatures in check. During fall, water temperatures drop from 27 °C (81 °F) to 21 °C (70 °F), which cools the air near the coast.
You’ll feel this effect even more in the evenings when breezes from the west or north bring in cooler, moist air.
Frost almost never happens, so plants stay active all year. Fall is still a growing season, though things slow down a bit as daylight fades.
Comparison With Other Seasons
Compared to summer, fall in Tripoli is much cooler and way more comfortable. Summer highs often hit 35–40 °C (95–104 °F) with almost no rain, but in fall, highs drop steadily into the low 20s Celsius.
Humidity also falls off sharply, so late fall doesn’t feel nearly as heavy.
Winter is cooler, but not rough. January highs average 16–18 °C (61–64 °F), which isn’t much lower than late November. Rain picks up in winter, but fall starts the wetter season.
Spring is different—temperatures rise quickly from March to May. In fall, you get a slow, steady cool-down. Spring skies tend to clear up, but in fall, cloud cover grows.
If you look at daylight, fall loses almost 3 hours between September and November. Spring gains about the same. This really changes how much time you want to be outside.
Average Fall Temperatures
In fall, Tripoli cools down from hot summer levels to much milder conditions by late November. Early in the season, days stay warm, but evenings turn cooler as the weeks go on.
Daytime and Nighttime Ranges
In early fall, daytime highs usually hit around 90°F (32°C), while nights stay near 74°F (23°C).
By late November, highs are closer to 70°F (21°C), and nights drop to about 55°F (13°C).
You might still want light clothes in September, but by November, a jacket feels a lot better in the evenings.
The gap between day and night temperatures gets bigger as fall goes on. Early in the season, nights are warm, but by November, the cooler evenings really stand out against the daytime warmth.
Temperature Trends by Month
September stays hot, with highs between 85–91°F (29–33°C). Nights are warm, averaging in the low to mid-70s°F (22–24°C).
October cools down noticeably. Highs usually run from 77–84°F (25–29°C), and nights fall into the mid-60s°F (18–20°C). Cooler mornings and evenings pop up more often.
November feels like a different season. Highs average around 70–74°F (21–23°C), and nights drop to 55–58°F (13–15°C). The cooler air and shorter days give Tripoli a distinctly mild autumn vibe after the summer heat.
Record Highs and Lows
Averages are helpful, but sometimes the weather surprises you. In fall, record highs have reached the upper 90s°F (36–37°C), especially in September.
These hot days don’t happen often, but they’re possible early in the season.
On the other end, record lows in late fall have dipped to about 50°F (10°C). Nights rarely get colder than that, but after a long, hot summer, it feels crisp.
Tripoli’s weather can swing a bit, even in a season that usually cools down steadily. If you visit, pack for warm afternoons and cool evenings.
Rainfall and Humidity During Fall
In fall, Tripoli finally starts to get rain again after the dry summer. Humidity changes too, shifting along with the new season.
You’ll see more precipitation and cloud cover, making things feel less dry than in August.
Monthly Precipitation Levels
Rain in Tripoli during fall is modest, but you can see it climbing as the months go by. September is mostly dry, with less than 5 mm of rain.
By October, average precipitation rises to around 30–40 mm, and in November it jumps to about 50–60 mm.
This pattern comes from the Mediterranean influence. Rain doesn’t fall evenly—it’s usually short, scattered showers.
Most of the rain comes later in the season, with November as the wettest fall month.
The extra rain helps cool down daytime temperatures, so things feel a lot more comfortable than in the blazing summer.
Totals aren’t huge compared to wetter places, but the difference between September and November is easy to spot.
Frequency of Rainy Days
Rainy days in Tripoli during fall are still pretty rare, but they do increase. September might pass without any real rain.
In October, you might get 2–3 rainy days, and by November, it’s usually 6–8 days with some rain.
Rain tends to come in quick bursts, not long storms. You still get plenty of clear or partly sunny days, even in November.
When it does rain, it can pour for a short time, then clear up quickly.
For travelers, this means fall is usually easy to manage—weather disruptions are rare. Still, it’s smart to bring a light rain jacket if you’re coming in November.
Humidity Variations
Humidity in Tripoli during fall shifts as the rain pattern changes. September stays dry, with relative humidity around 55–60%, still feeling a bit like summer.
By October, humidity edges up, and in November, it’s often 65–70% on average.
Cooler air and more clouds bring the increase. The air isn’t really damp, but mornings and evenings can feel a little more humid than the afternoons.
This makes the climate feel milder and less harsh than during the summer. Moderate humidity and cooler temps create better conditions for being outdoors or traveling around Tripoli.
Sunshine Hours and Cloud Cover
In fall, Tripoli gets less direct sunlight each day, and cloud cover becomes more common.
The change from long, bright days in early September to shorter, cloudier days by late November really shapes how you plan your time outside.
Average Daily Sunshine
At the start of September, you get almost 12 hours and 50 minutes of daylight. Skies are usually clear or mostly clear.
By late November, daylight drops to about 10 hours and 10 minutes. Both the length and intensity of sunshine take a hit.
Average daily solar energy falls fast. Early in the season, the ground gets about 6.7 kWh per square meter, but by late November, it’s down to around 3.1 kWh.
Outdoor activities feel brighter and warmer in September than in late fall.
Tripoli’s spot on the Mediterranean keeps sunshine pretty steady, even as days get shorter. Still, less solar intensity and stronger winds make late fall feel cooler.
| Month | Avg. Daylight Hours | Avg. Sunshine Intensity |
|---|---|---|
| September | ~12h 50m | High (6.7 kWh/m²) |
| October | ~11h 30m | Moderate |
| November | ~10h 10m | Lower (3.1 kWh/m²) |
Cloudiness Trends in Fall
Clear skies rule in early September, with conditions 95% clear or mostly clear.
As the season goes on, cloud cover increases. By early November, about one-third of the time is overcast or mostly cloudy.
The cloudiest stretch usually hits in early November, when the chance of overcast skies reaches 35%. This cuts down on bright sunlight and hints that winter’s on the way.
You’ll notice the change when you plan outdoor stuff. In September, evenings are still bright, and sunsets happen around 7:30 PM.
By late November, the sun sets closer to 6:00 PM, and clouds are more common.
These changes affect photography, sightseeing, and spending time by the coast. Early fall is best for golden light, while later months bring softer, filtered light thanks to the extra clouds.
Wind Patterns and Atmospheric Conditions
During fall, winds in Tripoli shift in both speed and direction. These breezes shape how the season feels.
The air stays mostly dry with mild humidity. Breezes often bring in cooler air, balancing out the last of the summer heat.
These wind patterns influence comfort, outdoor plans, and even how clear the sky looks.
Prevailing Winds in Fall
In Tripoli, fall winds usually come from the north and northwest. These winds move air inland from the Mediterranean Sea.
Most days, the wind feels steady and moderate, averaging around 5 mph. Sometimes, stronger gusts show up during the weeks when seasons shift.
The city sits right on the coast, so the sea breeze cools down daytime temperatures. This breeze keeps afternoons more comfortable than the sticky heat of summer.
At night, things can feel a bit warmer when the wind dies down and the heat sticks around.
Now and then, southern winds—locals call them Ghibli or Sirocco—blow in during fall. These winds bring hot, dry air from the desert and can spike temperatures for a day or two.
You won’t see these desert winds as much as you might in spring, but they’re still something to keep in mind if you’re heading outdoors.
Impact on Local Weather
The mix of Mediterranean breezes and those occasional desert winds really changes up the daily weather. Northerly winds usually bring clearer skies and lower humidity, which helps the air feel fresher.
That’s why fall ends up being one of the better times to spend time outside in Tripoli.
When the desert winds show up, expect hazier skies and a sudden jump in warmth. These spells don’t last long, but they can push daytime highs above the usual 72–81°F range.
Wind also plays a part in how rain falls. Light breezes from the sea sometimes carry in moisture, helping with those rare fall showers.
Even though rain barely happens, wind helps spread cooler air around the city, keeping things fairly balanced as summer fades into winter.
Travel Advice for Visiting Tripoli in Fall
Fall in Tripoli brings cooler days than summer, less humidity, and a slow increase in rainfall. You’ll notice shorter daylight hours and breezier afternoons.
The weather shifts from hot and dry to something a lot more comfortable—perfect for sightseeing if you ask me.
Best Times to Visit
Early fall, especially September, still feels pretty warm with highs around 30°C (86°F), but the humidity starts dropping off. By late October and November, daytime temperatures hover closer to 21°C (70°F), which makes walking tours or exploring the coast a lot more pleasant.
Rain chances tick up as fall goes on. September stays mostly dry, but November brings more frequent showers.
If you’re after mostly sunny days, you’ll want to visit in September or early October. If you’d rather have milder weather and fewer crowds, late October into November is your best bet.
Tourism slows down in fall compared to spring, so you’ll probably run into shorter lines at museums and fewer people in the markets. That’s a nice bonus for travel and weather alike.
What to Pack for Fall Weather
Bring clothes that can handle changing conditions. Light, breathable fabrics work for warm afternoons, and a light jacket or sweater helps when the evenings cool off.
You’ll want comfortable walking shoes since lots of attractions have uneven streets or old ruins.
Rain gets more likely later in fall, so toss a compact umbrella or light waterproof jacket into your bag. Sunglasses and sunscreen still matter in September and October since the sun doesn’t quit easily.
Here’s a quick packing guide:
| Item | Reason |
|---|---|
| Light shirts | Warm afternoons |
| Jacket/sweater | Cooler nights |
| Umbrella/rain jacket | Increasing rainfall |
| Comfortable shoes | Walking tours |
| Sunglasses/hat | Strong sun exposure |
Local Events and Activities
Fall feels like the perfect time to hang out on Tripoli’s Mediterranean coastline. The summer heat finally lets up. In September, the beaches stay nice, though by November the sea starts to cool down.
I find outdoor cafés and seaside walks way more enjoyable once the weather chills out a bit.
Markets and souks keep buzzing all year, but the cooler air really makes it easier to wander through textiles, spices, and crafts.
You can explore historical sites like the Red Castle (Assaraya al-Hamra) without sweating buckets.
Cultural events don’t pop up as often as they do in spring, but you’ll probably come across local music performances or small community gatherings if you look around.
The weather change also makes day trips inland more doable. You get the chance to check out Roman ruins like Leptis Magna without getting roasted by the sun.
