Overview of Kampot’s Spring Climate
Spring in Kampot brings steady warmth, high humidity, and a sharp rise in rainfall as summer monsoon season approaches. The air feels humid, clouds show up more often, and you’ll notice a clear jump in wet days compared to earlier in the year.

Kampot has a tropical monsoon climate, so temperatures stay warm and humidity stays high. During spring, daily highs usually sit between 84°F and 90°F (29°C–32°C), with lows from 77°F to 81°F (25°C–27°C). Nights stay warm, so don’t expect much relief from the daytime heat.
Humidity hits almost every day—99% of days are muggy—so you’ll feel damp most of the time. High dew points keep the air sticky, and even at night, things don’t really cool off or dry out.
The average surface water temperature in nearby coastal spots rises from about 83°F (28°C) to 86°F (30°C). That helps keep the air warm and the climate muggy. Winds shift a bit, blowing mostly from the south in early spring and then from the west by late May. Wind speeds pick up from about 6.7 mph to 8 mph as the season goes on.
Seasonal Weather Patterns
Clouds increase quickly as spring moves along. In early March, skies might be partly clear about half the time, but by late May, overcast or mostly cloudy days make up more than 90% of the time. That’s a sure sign the wet season’s coming.
Rainfall jumps up fast too. In early March, you’ll get less than 1 inch of rain over 31 days, but by late May, that can hit 8 to 9 inches. By the end of spring, rain feels almost constant, with wet days happening more than half the time.
Daylight hours get a little longer—from about 11 hours 55 minutes in early March to 12 hours 42 minutes by late May. Still, heavy cloud cover often blocks the sun, so you don’t get as much direct sunlight as you might expect.
If you’re planning to be outside, expect hot, humid, and increasingly wet weather. Rising rainfall, thick clouds, and sticky air really define Kampot’s spring.

Humidity makes the heat feel stronger. Even if the thermometer says 88°F, the air’s moisture amps it up. Light clothes, shade, and lots of water help if you’re outside.
Nighttime Temperature Trends
At night, temperatures stay warm—lows go from 77°F (25°C) in March to about 81°F (27°C) by late May. Nights don’t cool off much, so you won’t get much relief after sunset.
The warmest nights show up in late May, with average lows at 81°F (27°C). Even in March, when it’s “cooler,” nighttime temps rarely drop below 74°F (23°C).
Because the air stays humid, evenings feel muggy. A fan or air conditioning makes sleeping easier. If you’re close to the coast, you might catch a breeze, but inland areas are usually still and sticky.

Rainfall and Rainy Days During Spring
Spring in Kampot brings more rain as the dry season fades. You’ll see light showers early on, and by late spring, heavier downpours make outdoor plans more unpredictable.
Monthly Rainfall Totals
Rainfall in Kampot during spring changes fast. In March, you’ll get around 80–90 mm—not much compared to what’s coming. By April, rainfall bumps up to about 120–150 mm, showing the monsoon’s first hints.
May really ramps things up, often hitting 200–250 mm. That’s when frequent, heavier showers kick in. Rain doesn’t fall evenly, so you’ll get some dry days and some with intense afternoon storms.
| Month | Average Rainfall (mm) |
|---|---|
| March | ~83 mm |
| April | ~130 mm |
| May | ~220 mm |
This steady climb in rainfall makes May much wetter than March.
Frequency of Rainy Days
Rainy days increase fast through spring. In March, you’ll see 12–14 rainy days, so about half the month is dry. Showers usually come in the late afternoon and don’t last long.
By April, rainy days go up to about 15–17, so outdoor plans get interrupted more often. Rain is still manageable, but it starts to affect schedules.
In May, you’ll get 18–20 rainy days. Rain shows up almost every day, though it’s not always an all-day event. Expect at least part of the day to be wet, especially in the evenings.
Transition to Wet Season
Spring marks the shift from dry to wet season in Kampot. Both rainfall totals and rainy days steadily climb.
March still feels a bit like the dry season. April is the turning point, with more moisture in the air. By May, the wet season has basically started, with heavy showers and high humidity becoming the norm.
Travel can get tricky as the season turns. Roads might get muddy, and river levels start to rise. If you visit in late spring, bring rain gear and get ready for frequent showers—but hey, the landscapes get lush and green.
Sunshine Hours and Daylight Length
In Kampot during spring, you’ll notice changes in both sunshine hours and daylight length. Days get longer, but more cloud cover and rain cut down on direct sunlight.
Average Daily Sunshine Hours
Spring marks the shift from dry to wet season. In March, you might get 7 to 8 hours of sunshine per day, but by May, that drops to 5 to 6 hours as clouds roll in.
The drop is steady. March is still pretty bright, while April brings more humidity and haze. May sees afternoon storms that really cut down on sunlight.
For a quick comparison, January averages about 9 hours of sunshine daily, while September—the cloudiest month—drops to 4.9 hours. Spring lands somewhere in between, offering bright mornings and cloudier afternoons.
Changes in Daylight Duration
Daylight length in Kampot barely changes through the year since it’s near the equator. In spring, you get between 12.0 and 12.6 hours of daylight each day.
- March: about 12.1 hours
- April: about 12.4 hours
- May: about 12.6 hours
The increase is mild. You’ll notice earlier sunrises and slightly later sunsets as spring goes on.
Even though days get longer, you don’t always get more usable sunshine. Cloud cover and rain in late spring block out a lot of direct sunlight.
Cloud Cover Trends
Clouds are the main reason sunshine drops in spring. March still feels pretty clear, with lots of sunny stretches. By April, skies become more unpredictable, and you’ll see more partly cloudy to overcast days.
May brings the full wet season vibe. Afternoon storms and thick clouds really cut down on sunlight. Sometimes, you’ll only get short bursts of brightness between showers.
If you want to spend time outside, keep this in mind. Early spring gives you more blue skies, but late spring means you’ll need to work around clouds and less sunshine.
Wind Speed and Breezes in Spring
Spring in Kampot brings steady breezes that shape daily comfort and outdoor plans. Wind speeds change as the season goes on—calmer at first, then stronger as the monsoon approaches. These shifts affect how hot the air feels and whether things stay pleasant or turn sticky.
Monthly Average Wind Speed
From March to May, average wind speed gradually rises. Early March feels pretty calm, with light breezes around 5–6 mph. By April, winds pick up to about 7 mph, and in May, they often hit 8 mph or more as the wet season draws near.
Late spring feels different from early spring because of this. In March, still air can make the heat feel worse, especially with high humidity. By May, stronger winds move air across the coastal plain, though they can also bring more clouds.
Here’s a quick breakdown:
| Month | Avg. Wind Speed (mph) | Conditions |
|---|---|---|
| March | 5–6 | Light breeze, warmer feel |
| April | ~7 | Moderate breeze, some relief |
| May | 8+ | Stronger winds, more cloudiness |
You’ll notice winds get stronger as spring heads toward the peak of monsoon season.
Impact of Wind on Weather Comfort
Wind strength shapes how you actually feel Kampot’s spring weather. In March, you might notice a light breeze, but honestly, it doesn’t do much to cut the heat, so afternoons still feel heavy and humid.
April brings in moderate winds that can finally bring some comfort, especially if you find some shade or hang out in open spaces.
By May, stronger winds cool things down a bit, but they also stir up more moisture. That means evenings often feel sticky, even when it’s cooler outside.
These breezier days also mark the shift toward the rainy season, so you’ll notice skies staying cloudy more often.
If you love biking or riverside walks, you’ll want to pay attention to wind speeds in spring.
March usually gives you calmer days, perfect for relaxed outings.
April and May get gustier, making the weather a bit unpredictable.
Some people find May’s windier afternoons great for cooling off, but honestly, it’s not always ideal if you’re hoping for a smooth river cruise.
Humidity and Atmospheric Conditions
Kampot’s spring feels humid and heavy, with the air packed full of moisture. The muggy conditions barely let up, day or night, and that can really impact your comfort and outdoor planning.
Average Spring Humidity Levels
Humidity in Kampot during spring sticks around for almost 100% of days, so it’s muggy pretty much all the time. Dew points stay high, which means sweat just sits there and doesn’t evaporate easily, making the air feel even heavier.
Temperature goes up and down, but humidity barely budges.
You’ll notice mornings feel just as damp as afternoons.
By May, the air gets even more oppressive, and honestly, it’s tough to spot much difference from earlier in the season.
Rainfall really ramps up too, jumping from under 1 inch in early March to over 9 inches by late May.
That just adds to the sticky feeling.
Clouds start crowding the sky as spring goes on.
Early March gives you partly clear skies about half the time, but by late May, overcast days take over more than 90% of the time.
So, you end up with a warm, moist environment that rarely feels dry.
Effects on Outdoor Activities
All that dampness really changes how you spend time outside.
Walking or biking gets tiring fast because you don’t get much evaporative cooling.
Even at night, the air stays muggy—you won’t find much relief after sunset.
If sightseeing is your thing, plan for shorter outings and take plenty of breaks indoors or in the shade.
Wearing light, breathable clothing helps, and don’t forget to bring water to help with heat stress.
Rain picks up as spring goes on, so river cruises or hikes might get interrupted.
Trails and roads can turn muddy, and those sudden showers can really catch you off guard.
Try to schedule outdoor plans earlier in the day, since rain is a bit less likely then.
Travel Tips for Experiencing Kampot’s Spring Weather
Kampot’s spring feels hot, humid, and honestly, pretty rainy—especially from April into May.
You’ll enjoy the season a lot more if you plan around the daily weather and pack the right clothes and gear.
Best Times of Day to Explore
Morning is hands-down the best time to get out and explore Kampot in spring.
Temperatures usually hover between 75°F and 82°F (24°C–28°C) before climbing later.
Humidity is a bit lower, and you’ll often get clearer skies, so it’s a great window for walking tours, hitting the markets, or riverside activities.
By late morning, the heat ramps up fast.
Afternoon highs often hit 88°F–90°F (31°C–32°C), and the humidity just makes it feel hotter.
Rain showers pop up more often after midday, especially in April and May.
Evenings cool off to around 80°F (27°C), so you might want to eat outside or catch a sunset boat ride on the Kampot River.
Just don’t forget the mosquito repellent—those little guys get really active at dusk.
Packing Recommendations for Spring
You’ll want lightweight, breathable clothes for spring. I usually go for cotton or linen fabrics since they let air in and help wick away sweat.
Short sleeves and loose pants or shorts keep you cooler than anything heavy or tight.
Grab a light rain jacket or poncho, because spring showers can hit out of nowhere and get intense fast.
Quick-dry footwear or sandals with a decent grip make more sense than heavy shoes, especially if the streets get soaked.
Don’t forget sun protection—a wide-brimmed hat, sunglasses, and some high-SPF sunscreen. The UV index can sneak up on you, even when it’s cloudy.
I’d also toss a small day bag into your packing list. Fill it with bottled water, insect repellent, and maybe a portable fan or a cooling towel.
This way, you’ll stay hydrated and comfortable while you bounce between indoor and outdoor spots.
