Overview of Fall Weather in Kampot

Fall in Kampot, Cambodia brings steady warmth, high humidity, and a noticeable shift from heavy rains to drier skies. You’ll get consistent temperatures, shorter days, and changing wind patterns as the season moves along.

Seasonal Climate Patterns

During fall, Kampot’s daily highs usually stick close to 86°F (30°C). Lows average about 78°F (25°C), so nights stay warm and humid.

The air feels muggy most of the time. Dew points rarely drop enough to give you much relief.

Rain falls often at the start of the season. September can bring heavy downpours, with averages near 12–13 inches of rain.

By November, rainfall drops sharply to about 2 inches. This signals the approach of the dry season.

Cloud cover decreases over the months. Early fall skies are overcast nearly 90% of the time, but by late November, cloudy conditions fall closer to 65%.

This clearing means more sunshine and brighter afternoons.

Winds shift as well. In September and early October, breezes usually blow from the west. By late October and November, winds come from the east at lower speeds, averaging about 7–9 mph.

Typical Fall Weather Timeline

September: This month is among the wettest. Frequent thunderstorms and heavy showers, often in the afternoon or evening, are common. Humidity stays high, and skies remain mostly cloudy.

October: Rainfall starts to ease, but showers still happen regularly. Winds weaken, and you’ll see more breaks of sun. Temperatures hold steady, with little difference between day and night.

November: By now, the weather stabilizes. Rain becomes less frequent, and skies clear up. Daylight hours shorten to about 11.5 hours, and sunsets come earlier. November marks the transition into Kampot’s dry season.

Comparison to Other Seasons

Compared to winter, fall is wetter and cloudier. Winter brings less rain, clearer skies, and slightly cooler nights, dipping to around 75°F (24°C).

Spring in Kampot gets hotter, with highs often reaching 90°F (32°C). Humidity stays high, but there’s less rain than in fall.

Summer is the monsoon’s peak—rainfall and cloud cover are at their highest, and outdoor activities can be tough. Fall sits between this wettest period and the much drier winter, offering a blend of rain and sun.

Average Fall Temperatures

In fall, Kampot gives you steady warmth with only small temperature changes. Days stay hot but not extreme, and nights cool off a bit, offering some relief from daytime heat.

Daytime Temperature Trends

Daytime temperatures during fall average around 86°F (30°C). This stays pretty consistent across September, October, and November, with only minor month-to-month changes.

Expect warm, humid afternoons, especially early in fall when cloud cover lingers. October often feels the most humid, though the temperature itself doesn’t rise much above earlier months.

Unlike places where fall means a sharp drop in daytime heat, Kampot’s tropical climate keeps afternoons hot and steady. If you’re planning outdoor activities, try to schedule them earlier in the day to dodge the peak warmth.

Nighttime Temperature Ranges

Nights bring a bit more comfort, with lows between 75°F and 77°F (24°C–25°C). Temperatures rarely fall below 71°F, so you won’t need heavy clothes.

Humidity at night can make things feel warmer than the thermometer says. This is especially noticeable in September, when clouds still hang around.

By November, clearer skies help nights feel just a bit cooler.

If you’re staying somewhere without air conditioning, you’ll probably still want a fan. Nights aren’t cold, but the mix of warmth and humidity can make it tough to sleep without some airflow.

Monthly Temperature Variation

From September to November, average daily highs stick close to 86°F with barely any fluctuation. Lows shift just a bit, from about 77°F in September to around 75°F in November.

You won’t notice a big seasonal difference in temperatures. The main changes come from cloud cover and rainfall, not the thermometer.

Here’s a quick breakdown:

These steady numbers show why Kampot’s fall weather feels so stable, with only a gradual easing of nighttime heat.

Rainfall and Precipitation in Fall

Rain in Kampot during fall shifts from heavy downpours at the start of the season to lighter showers by the end. You’ll notice big changes in both the total amount of rain and how often it falls as the monsoon weakens.

Monthly Rainfall Totals

September is usually the wettest fall month in Kampot. Average rainfall can top 13 inches (about 340 mm), making it one of the rainiest times of year.

By October, totals drop fast, often landing around 7–8 inches (180–200 mm).

In November, rainfall decreases even more. You’ll typically see 2–3 inches (50–80 mm), which signals the shift toward the dry season.

These numbers really show how quickly the wet season fades, giving you clearer skies as the year winds down.

Frequency of Rainy Days

Rainy days follow the same downward slide. In September, you’ll get rain on two-thirds of the days, often as intense afternoon or evening storms.

By October, the chance of rain drops to about 40–50% of days. Showers still happen, but they’re less frequent and usually shorter.

November brings a noticeable difference. Rain falls on only about one week of the month on average. Most days are dry, and when it does rain, it’s usually brief.

This drop in rainy days makes it much easier to plan outdoor activities as fall moves along.

Impact of Monsoon Season

The southwest monsoon overlaps with fall in Kampot and drives those heavy September rains. Monsoon winds carry moisture from the Gulf of Thailand, fueling frequent storms and high humidity.

By October, as the monsoon weakens, rainfall intensity and duration drop off. November usually sees the system retreat, leaving behind drier air and more sunshine.

For travelers, September can be the toughest month, with flooding risks and muddy roads. By late fall, conditions improve, and November becomes a much more appealing time to explore Kampot and its surroundings.

Humidity and Comfort Levels

Fall in Kampot often feels heavy because of the high moisture in the air. Temperatures stay warm, but the real challenge is the elevated relative humidity, especially in September and October when rain is frequent.

Average Relative Humidity

During fall, relative humidity levels sit between 80% and 88%. This makes the air feel warmer than the thermometer reads, which usually hovers in the mid-80s °F (29–30°C).

High humidity slows down how fast your body cools off through sweat. You might feel sticky or overheated even if you’re not doing much.

Here’s a quick look at average humidity:

These levels are high compared to a lot of places, so it’s smart to plan slower-paced activities and take advantage of shade or air conditioning when you can.

Seasonal Fluctuations

Humidity in Kampot shifts with the monsoon cycle. September and October are the peak rainy months, so humidity is at its highest. Mornings and evenings feel damp, and there’s not much relief during the day.

By November, as rainfall decreases, humidity starts to ease. Levels drop to the mid‑70s, making the air feel less oppressive.

This change really improves outdoor comfort, especially for walking, biking, or hanging out by the river.

As the wet season transitions to the dry, you’ll get clearer skies and drier air. While it’s still humid by most standards, the difference is noticeable. November usually feels much better for spending long stretches outside.

Wind Speed and Weather Conditions

During fall in Kampot, you’ll get steady but moderate winds along with warm, humid air. These conditions shape both outdoor comfort and how people plan their daily routines.

Typical Wind Speed Ranges

Wind speeds in Kampot during fall usually land between 6 to 12 knots (about 11–22 km/h). That’s enough for a noticeable breeze but not strong enough to disrupt most activities.

Winds shift with seasonal changes. At the start of fall, they come from the southwest, then gradually ease as the dry season gets closer.

You might notice stronger gusts along the coast or in open fields. Inland, especially near the river, natural barriers cut the wind down a bit. Calm days still show up, but they’re less common than in the dry season.

Here’s a basic rundown of average conditions:

Influence on Daily Life

The steady breeze in fall actually helps a lot. Outdoor markets and riverside cafés feel more comfortable because the airflow takes the edge off the humidity.

For travelers, these winds make cycling, boating, and sightseeing more pleasant. The breeze helps offset the heat, especially around midday when temperatures climb above 30°C.

Local fishermen and boat operators rely on predictable wind speeds for safe navigation. Moderate winds let small boats travel safely, though sudden gusts can still change plans.

If you’re into kitesurfing or sailing, fall offers steady but not extreme conditions. The winds are reliable enough for water sports, but mild enough that beginners can try them without worrying about hazardous weather.

Sunshine and UV Index During Fall

In the fall months, Kampot sees daylight hours shrink a bit, and clouds roll in more often, especially in September and October. Sunshine just can’t compete with the dry season, but the UV index still packs a punch—so don’t forget to protect yourself if you’re heading outside.

Average Daily Sunshine Hours

September really stands out as the gloomiest month. You might only catch about 4.5 to 5 hours of sun each day, since clouds and rain show up a lot. Honestly, it’s one of the least sunny stretches in Kampot.

October brings a bit of a break. The average sunshine bumps up to around 5 to 6 hours daily, though you’ll still get your fair share of showers.

By November, the skies finally clear up more. You can usually expect 7 to 8 hours of sun per day as the rainy season starts to wind down.

If you love bright days, late fall is your best bet for outdoor activities. Here’s a quick look:

So, depending on when you drop by Kampot in the fall, your experience could be pretty different.

UV Index Levels

Even though September and October bring less sunshine, the UV index stays high. Most days, you’ll see levels from 8 to 11. That’s very high to extreme—enough to cause skin damage in under 30 minutes if you’re not careful.

When November rolls around, the skies clear up more often. Still, the UV index doesn’t really drop much. You should treat all the fall months as times when the sun packs a punch.

Honestly, it’s smart to wear broad-spectrum sunscreen and grab some UV-blocking sunglasses. Try to find shade around midday, too.

Lightweight, long-sleeved shirts can help cover up and keep your skin safer.

Clouds or rain don’t block UV rays, so don’t skip your protection just because the weather looks dull. If you’re heading out to Kampot’s riverside, pepper farms, or the coast, this matters even more.
