Fall in Beirut feels like a welcome break from the hot summer. The Mediterranean coast cools down, and you’ll notice afternoons in September still hit the low 80s °F, but by late November, they slide into the upper 60s °F.
Nights get cooler as well, so strolling the city feels more comfortable. It’s honestly one of the best times to wander around.
Skies change fast during fall. Early on, you’ll see a lot of clear, sunny days, but by November, cloud cover and rain start to show up more often.
This shift affects everything—how much daylight you get, or whether you’ll want to grab a light jacket or umbrella before heading out.
Steady sea breezes, shorter days, and less humidity than summer create a nice mix of comfort and variety. These conditions really set the mood for Beirut’s fall weather—from temperature swings and rainfall to daylight hours and travel tips.
Overview of Fall Weather in Beirut
Fall in Beirut means cooler temperatures, shorter days, and a steady climb in rainfall. Early September starts out warm and dry, but by late November, things turn cooler and wetter, changing how you enjoy the city.
Key Climate Characteristics
Daily highs drop from about 86°F (30°C) in early September to near 70°F (21°C) by late November. Nights cool down even more, going from the mid-70s °F (24°C) to the upper 50s °F (15°C).
Rain picks up as the season goes on. September barely sees any, but in November, you’ll get around 2–3 inches (50–75 mm) for the month. The odds of a rainy day go from almost nothing to about 23% by the end of fall.
Clouds roll in more often too. September skies usually stay clear, but by November, you’ll get more overcast days. Winds usually stay light to moderate, around 6–8 mph (10–13 km/h), mostly coming from the west.
Transition from Summer to Fall
Humidity drops noticeably as summer fades. Early September can feel sticky and humid, but by November, the air dries out and feels much more comfortable.
The chance of muggy weather falls from over 80% in September to almost nothing by late fall.
Daylight disappears fast. In September, the sun sets after 7:00 PM, but by late November, it’s gone before 4:30 PM. That’s nearly three hours less daylight, which definitely changes how you plan your day.
Sea temperatures cool off too, from about 83°F (28°C) in September to 71°F (22°C) in November. Swimming feels great in early fall, but by November, the water gets a bit too chilly for most folks.
Comparison with Other Seasons
Fall feels cooler and less sticky than summer, so it’s much nicer for being outside. Rain starts returning after the dry summer, setting things up for the wetter winter ahead.
Winter brings cooler temps and a lot more rain, with highs in the 50s °F (10–15°C). Spring is pretty mild and pleasant, sort of like fall but usually with less rain.
If you like warm weather without the summer heat, fall is the sweet spot. It’s a great time for sightseeing, and the city isn’t as crowded as in peak summer.
Typical Temperatures During Fall
Temperatures in Beirut drop steadily from hot to cool as fall goes on. You’ll feel the change in both daytime highs and nighttime lows, and the humidity shift makes things even more noticeable.
Average Highs and Lows
In September, average highs hit around 86°F (30°C), while nights stay near 77°F (25°C). By November, highs cool to about 70°F (21°C), and lows drop to 59°F (15°C).
Early fall feels warm and humid, but by late fall, you get mild days and cool nights.
Here’s a quick breakdown:
| Month | Avg High | Avg Low |
|---|---|---|
| September | 86°F / 30°C | 77°F / 25°C |
| October | 79°F / 26°C | 67°F / 19°C |
| November | 70°F / 21°C | 59°F / 15°C |
These numbers help you figure out what to pack—summer clothes for September, maybe a light jacket for November evenings.
Daily Temperature Fluctuations
Day-to-night swings aren’t extreme, but you’ll notice them more as fall goes on. In September, the gap between day and night is usually 6–9°F (3–5°C). By November, it widens to 10–12°F (5–7°C).
Afternoons often stay warm enough for short sleeves, but evenings, especially by the water, can feel cool.
Humidity drops a lot as the season moves forward. Early September is muggy, but by November, the air feels crisp and dry, making outdoor plans much more enjoyable.
If you’re near the coast, the Mediterranean keeps nights from getting too chilly, which is nice.
Record Temperature Extremes
Averages tell most of the story, but sometimes you get outliers. In early fall, hot days can still push into the upper 80s°F (31–32°C), especially if desert winds blow in.
On the other end, late fall nights might dip into the low 50s°F (11–12°C), but that’s rare. Beirut doesn’t get frost or freezing temps in fall, thanks to its spot on the coast.
These extremes don’t happen often, but it’s smart to pack for both warm afternoons and cool nights, just in case.
Rainfall and Precipitation Patterns
Beirut shifts out of a dry summer and into a wetter fall as cooler air moves in from the Mediterranean. Rain picks up steadily, and you’ll start to notice more rainy days as the rainy season begins.
Monthly Rainfall Totals
Rainfall rises each month through fall. September is usually dry—just 5–10 mm of rain. October jumps to around 60–70 mm, and by November, totals often pass 110 mm.
That’s the Mediterranean climate at work—long dry summers, but once fall starts, moisture climbs fast.
By November, you’ll get heavier rain bursts, not just the light showers of early autumn.
| Month | Avg. Rainfall (mm) |
|---|---|
| September | ~5–10 |
| October | ~60–70 |
| November | ~110–120 |
Onset of the Rainy Season
The rainy season usually kicks in around late October. Before that, September and early October mostly stay warm and dry, with just a few stray showers.
By mid to late October, Mediterranean weather systems bring the first real rain. These storms can be quick but pretty intense, marking the end of the dry stretch.
By November, rain becomes a regular thing, and Beirut settles into a cooler, wetter rhythm that will last through winter. If you’re planning outdoor stuff, keep in mind that the window for dry days closes fast after early October.
Number of Wet Days
The number of rainy days climbs through fall. In September, rain is rare—maybe 0–1 wet days on average. October usually has 5–6 wet days, and November gets about 8–10.
You’ll definitely notice the change. Showers don’t usually last all day, but they’re frequent enough to mess with plans.
Rain in Beirut tends to come in bursts, not a steady drizzle. You might have dry spells for hours, then get hit with a heavy shower out of nowhere. November, in particular, feels unpredictable compared to earlier in fall.
Humidity and Atmospheric Conditions
Humidity really shapes how Beirut’s fall weather feels. Even as temps cool off, the air can still be moist, which affects how comfortable you feel outside.
Average Humidity Levels
Beirut’s average yearly relative humidity sits at about 66%. In fall, it usually ranges from 60% to 68%, depending on the month.
September sticks closer to summer’s humidity, but by November, it drops to around 60%, which feels a lot lighter.
That makes outdoor time more enjoyable, especially compared to the sticky summer months. You’ll notice evenings feel fresher as humidity drops.
Humidity changes how warm the air feels, too. A 25°C day in October can feel warmer if humidity is high, but the same temp in late November feels milder thanks to drier air.
Seasonal Shifts in Humidity
As summer fades, Beirut’s atmosphere shifts. September still brings some lingering heat and higher humidity, so it can feel sticky during the day.
By October, humidity starts to ease. Skies clear up, there’s less condensation, and mornings and evenings feel more comfortable. Lower moisture also means better visibility along the coast.
In November, humidity drops further as temperatures cool. This time of year feels fresher, without the dampness you get earlier in the season.
If you’re visiting, you can expect more pleasant walking conditions, drier air indoors, and fewer days with that heavy, humid feel from late summer.
Sunshine and Daylight Hours
Fall in Beirut brings a steady drop in sunshine and daylight. Days get shorter, and you’ll see less direct sun than in summer.
Average Daily Sunlight
September still gives you about 9 to 10 hours of sunshine per day, so early fall stays bright. In October, this drops to around 8 hours, and by November, you get just 6 to 7 hours.
That means outdoor plans that need lots of daylight get a bit trickier as fall goes on. Still, September has plenty of sunny days, with clear skies for much of the month.
Sunny daylight hours drop too. In September, about 79% of daylight hours are sunny, but by November, that falls to 65%. More clouds and shorter days bring on that autumn mood.
Changes in Day Length Through Fall
Day length shrinks pretty quickly in Beirut during fall. Early September gives you about 12 hours and 20 minutes of daylight. By October, you’re down to roughly 11 hours and 15 minutes, and November has just over 10 hours.
That’s more than 2 hours of daylight lost from early September to late November. Sunrise and sunset times shift, and evenings get noticeably shorter.
The sun’s angle drops too. At noon, it goes from about 56.8° in September to 36.2° in November. That lower angle means sunlight isn’t as strong, and it feels cooler even on clear days.
Other Seasonal Factors and Travel Tips
In Beirut’s fall, the sun still packs a punch now and then, but evenings cool down fast and weather can change quickly. You’ll want to plan for shifting daylight, less humidity, and activities that make the most of the comfortable weather.
UV Index and Sun Safety
Even though temperatures drop from early to late fall, the Mediterranean sun can still pack a punch. The UV index usually sits at moderate to high levels, especially in September and early October.
If you stay out too long without protection, you might end up with a sunburn. So, don’t skip the broad-spectrum sunscreen—aim for at least SPF 30, even if it’s just a partly cloudy day.
A wide-brimmed hat and UV-blocking sunglasses really help with the glare, especially if you’re near the coast. By November, the UV index drops as days get shorter, but you still need sun protection.
The sea and those pale pavements reflect sunlight, which boosts your exposure. If you’re thinking about long walks along the Corniche or want to check out outdoor sites, try to go in the morning or late afternoon when the sun isn’t as harsh.
That way, you dodge both the heat and the strongest UV rays.
Packing Recommendations for Fall
Packing for Beirut in fall is a bit of a balancing act. Early in the season, daytime highs can still hit the upper 20s °C, so you’ll want some lightweight clothes.
By late November, evenings often dip close to 15°C, so a light jacket or sweater comes in handy. Here’s a practical list to consider:
- Breathable shirts for those warm afternoons
- Long pants for when nights get chilly
- Light jacket or cardigan
- Comfortable walking shoes for all the mixed terrain
- Umbrella or compact raincoat since November brings more showers
Humidity drops as the season goes on, so you don’t need heavy fabrics. Go for layers you can toss on or peel off as needed.
If you’re hoping to swim, sea temperatures stay warm through October, so it’s worth packing a swimsuit. By late fall, the water cools down, but hey, some folks still brave a quick dip.
Popular Outdoor Activities
Honestly, fall might be the best time to get outside in Beirut. The weather stays warm enough for seaside walks, but you won’t overheat during a city tour.
You’ll find plenty of people jogging, cycling, or just wandering along the Corniche, that long stretch by the water.
Outdoor cafes and rooftop terraces are still buzzing for most of the season. Eating outside feels way better without the summer’s intense heat.
Rainfall picks up in October and November, but you’ll still get mostly dry days for exploring. Lots of folks take the chance to visit mountain villages or check out archaeological sites like Byblos while the weather’s mild.
If you’re into water sports, September and early October work well since the sea stays at a comfortable 26–28°C. Later on, when it cools down inland, hiking really starts to call your name.
Since daylight hours get shorter, it’s smart to start your plans earlier. By late November, sunsets sneak in before 5:00 pm, so you’ll want to wrap up outdoor adventures a bit sooner.
