Thinking about a trip to Hua Hin in the fall? You’ll want to get ready for warm days, humid air, and a shift from rainy weather to clearer skies.
Daytime highs usually stick around the mid to upper 80s Fahrenheit, while nights settle comfortably in the 70s. Rainfall drops off fast as fall moves along, so late fall often feels drier and, honestly, just more inviting.
As the weeks go by, you’ll probably notice the air feels a little less heavy, though humidity doesn’t disappear completely. Cloud cover starts thinning out, giving you more hours of sunshine by the time November rolls around.
The sea stays warm—water temperatures average in the mid-80s—so swimming or hanging out by the coast remains a solid option.
Winds shift from the west to the north, which brings in slightly fresher air as the season goes on. With shorter days and earlier sunsets, Hua Hin’s fall feels like a slow, steady move from the wet months into the dry season.
You’ll get pretty reliable weather for outdoor plans and travel.
Overview of Fall Weather in Hua Hin
Fall in Hua Hin brings warm temperatures, high humidity, and frequent rain that drops off toward the end of the season.
You’ll find steady warmth both day and night, with only small changes in temperature compared to other times of year.
Typical Fall Climate Patterns
During fall, daily highs in Hua Hin usually stay between 84°F and 87°F (29–31°C).
Nighttime lows average around 75–77°F (24–25°C), so evenings stay warm and humid. Unlike some places, you don’t get a sharp drop between day and night.
Rainfall hits hardest in September and October, with October often seeing over 7 inches (180–200 mm) of rain.
Showers usually come down hard but don’t last long, often showing up in the afternoon or evening. By late October, rain chances drop, and you’ll see clearer skies more often.
Humidity stays high—often above 90%—so the air feels muggy through most of fall.
Winds tend to be light to moderate, shifting from the west early in the season to the north later on. Sea surface temperatures hang around 84°F (29°C), so swimming conditions rarely disappoint.
Comparison to Other Seasons
Compared to the hot season in April and May, fall in Hua Hin feels a bit cooler but a lot wetter.
The hot season pushes highs above 92°F (33°C), and rain offers little relief. Fall, on the other hand, brings more clouds and frequent storms that help keep the heat in check.
If you look at the cool season in December and January, fall stands out as more humid and unsettled.
The cool season brings drier air, clearer skies, and average highs closer to 85°F (29°C), with nights dipping to the low 70s°F (21–23°C).
Fall is also unique for its transition. Early fall is all about the monsoon, but late fall starts hinting at the dry months ahead.
If you’re planning outdoor adventures or beach days, this shift can make a difference.
How Hua Hin Differs from Broader Thailand Weather
Hua Hin’s fall weather gets shaped by its spot along the Gulf of Thailand.
You’ll see slightly less rainfall here than in Bangkok or Chiang Mai, where storms often last longer and hit harder.
The sea breeze helps take the edge off the heat, making things a bit more manageable than inland.
Northern Thailand, places like Chiang Mai, goes through a sharper seasonal change.
Rainfall drops off faster after September up north, and nights get much cooler. Hua Hin, though, keeps its nights warm and humidity pretty steady all season.
Southern Thailand—think Phuket—often deals with higher rainfall totals than Hua Hin during fall.
So, if you want a balance between beach weather and manageable rain, Hua Hin’s a solid pick. The mix of steady warmth, high humidity, and moderate rain gives Hua Hin its own fall vibe within Thailand.
Temperature Trends During Fall
In Hua Hin, fall brings a slow drop in heat, less humidity, and milder nights.
You’ll get warm afternoons, comfortable evenings, and fewer extremes than in the wet season.
Average Highs and Lows
During fall, daily highs in Hua Hin usually range from 32°C (90°F) in early September down to about 30°C (86°F) by late November.
Highs rarely go above 34°C, so you’re spared from serious heat.
Nighttime lows stick near 25°C (77°F) throughout the season.
They almost never drop below 22°C, so evenings stay warm but not overly hot.
This shift brings a more stable climate compared to summer.
You’ll notice less day-to-day variation, which makes planning outdoor activities easier.
Quick reference:
- September highs: ~32°C / 90°F
- November highs: ~30°C / 86°F
- Lows (all season): 22–27°C / 72–81°F
Day-to-Night Temperature Variation
The gap between daytime highs and nighttime lows in Hua Hin during fall is pretty small.
Most days, you’ll see just a 5–7°C (9–12°F) difference.
This keeps things consistent. You won’t need to pack heavy layers for evenings—nights stay warm and humid.
A light shirt or something breathable is usually enough.
The Gulf of Thailand helps regulate temperatures, since the sea stays around 29°C (84°F).
That means nights don’t cool off sharply, making the climate more predictable and comfortable than inland.
Mornings feel a bit cooler, evenings are pleasant, but afternoons still bring the most heat.
Monthly Temperature Changes
From September to November, Hua Hin’s weather slowly shifts toward cooler conditions.
Early September often feels hot and humid, with highs near 32°C.
By October, highs drop closer to 31°C, and by late November, they settle around 30°C.
Lows hold steady near 25°C, but late November nights might dip to 22°C.
That makes November the most comfortable fall month for outdoor plans.
The steady cooling lines up with less rain and fewer clouds.
As the season goes on, you’ll notice clearer skies, lower humidity, and slightly cooler evenings—definitely a more pleasant setup for travel or daily life.
Humidity and Dew Point in the Fall
During fall in Hua Hin, you’ll feel a gradual shift from the wetter months toward drier air.
Humidity stays noticeable, but it drops off bit by bit. The dew point also eases, making things feel less sticky as the season goes on.
Average Humidity Levels
Humidity in Hua Hin during fall stays high compared to many coastal spots.
In September, average relative humidity sits around 78–80%, so the air feels heavy and damp.
By November, it drops to about 70–72%, which is a little easier for outdoor activities.
This drop ties in with the end of the monsoon.
September and October bring clouds and humidity, while November offers clearer skies and lighter air.
You’ll probably notice mornings feel sticky early on, but by late fall, evenings aren’t as muggy.
- September: ~79%
- October: ~80% (peak humidity)
- November: ~71%
If you’re sensitive to humidity, early fall can be a bit much.
But things get better as the weeks go by, making late fall a nicer time to hit the beaches or markets without constantly feeling overheated.
Dew Point Fluctuations
The dew point gives you a real sense of how humid the air feels.
In Hua Hin’s fall, dew points usually run 24–26°C (75–79°F) in September and October—very humid.
By November, they drop to around 22–23°C (72–73°F), which brings some relief.
High dew points in early fall make it tough for sweat to evaporate, so you might feel sticky even if you’re just walking around.
As the season moves on, lower dew points mean the heat feels less oppressive, even if the temperature stays about the same.
Here’s a quick guide:
- Above 24°C (75°F): Very humid, uncomfortable
- 22–23°C (72–73°F): Humid but tolerable
- Below 21°C (70°F): Comfortable for most
By late November, lower dew points and less rain combine for pleasant conditions—great for getting outside or traveling around.
Rainfall and Precipitation Patterns
In Hua Hin, fall months bring heavier rain at first, then a quick shift to drier weather as the season wraps up.
You’ll see big changes in both the amount of rain and the number of wet days from month to month.
Monthly Rainfall Totals
Rainfall peaks in October, which is the wettest month of the year.
You can expect 200–250 mm of rain then.
September also brings heavy rain, often over 150 mm.
November, though, drops off quickly.
By late November, totals fall to 50–80 mm, which means the dry season is on the way.
Check out the average precipitation by month:
| Month | Average Rainfall (mm) |
|---|---|
| September | ~150–170 |
| October | ~200–250 |
| November | ~50–80 |
You can really see how fast rainfall drops as the season changes.
Frequency of Wet Days
The number of rainy days also shifts a lot through fall.
September usually brings 15–18 wet days, often with afternoon or evening showers.
October averages around 16–20 rainy days, so it’s the most unsettled stretch.
By November, you get just 6–8 wet days, so there are longer dry stretches.
This drop matters if you’re planning outdoor stuff—rain won’t get in your way as much in late fall.
Even in the rainiest months, showers tend to come in bursts, not all day long.
You’ll often get a heavy downpour, then things clear up—pretty classic for the tropics.
Transition from Rainy to Dry Season
The move from October into November marks the switch from rainy to dry season.
You’ll feel this not just in the rain, but in the air itself.
Humidity drops, and sunshine hours climb.
By late November, Hua Hin feels much drier, with rain becoming more occasional than regular.
This change doesn’t happen overnight, but you’ll notice it—especially if you compare early November storms to the clearer skies at month’s end.
Cloud Cover and Sunshine
During fall in Hua Hin, skies go from heavy cloud cover to clearer as the weeks pass.
You’ll see fewer overcast days and more sunshine hours by late November.
Overcast and Cloudy Days
Early fall in Hua Hin brings lots of overcast skies, with clouds covering the sky about 90% of the time in early September.
That makes the start of the season feel pretty gray and damp, especially with the rainy season still hanging on.
By late November, things look different.
The time spent under mostly cloudy or overcast skies drops to about 60%.
You’ll notice fewer gloomy days as fall goes on.
The cloudiest stretch matches up with the rainiest weeks in late September and early October.
If you’re planning outdoor activities, early fall might require a little flexibility thanks to all the cloud cover.
Clear Skies and Sunlight Hours
As clouds thin out, Hua Hin starts seeing more clear or partly clear skies. By late November, you might enjoy clear conditions nearly 40% of the time.
This makes the later part of fall better for beach outings and sightseeing. Sunlight hours also improve, finally.
In September, sunshine can be scarce, with only about 3–4 hours per day. By November, you get closer to 6–7 hours of usable daylight.
This shift from short, dim days to brighter afternoons really changes the atmosphere. If you like more reliable sunshine, late fall seems like the best time to visit Hua Hin.
Wind and Atmospheric Conditions
During fall in Hua Hin, steady breezes pick up and wind patterns start to shift as the rainy season fades. The air often feels humid, but winds help ease the heat and keep the coast more comfortable.
Average Wind Speed
Hua Hin usually sees moderate wind speeds in the fall, averaging 6 to 10 knots (about 11 to 18 km/h). These winds provide relief from humidity but don’t often cause any trouble.
Most days, the wind stays pretty steady during daylight, then calms down a bit at night. Outdoor activities like walking the beach or eating outside feel more pleasant because of this.
You might notice stronger gusts during rain showers, especially in September when the wet season still lingers. By October and November, winds settle down and become less unpredictable.
For water sports like kitesurfing or sailing, these winds work for casual fun, but advanced riders might want more. Still, most beachgoers enjoy the cooling breeze.
Prevailing Wind Direction
In fall, the prevailing wind direction in Hua Hin shifts with the monsoon. Early in the season, winds usually come from the southwest, bringing moisture from the Gulf of Thailand.
This adds to scattered rain and cloudy skies in September. By late October and November, winds turn more northeasterly.
That shift brings in drier air and steadier weather. The northeast flow is usually gentler, making the air feel lighter and the skies clearer.
Travelers find this change much more comfortable, and sudden storms become less likely. Sailors and kiteboarders often tweak their plans based on these wind shifts.
If you know whether winds come from the southwest or northeast, you can plan safer and more enjoyable days on the water.
Other Environmental Factors and Seasonal Effects
During fall in Hua Hin, you deal with strong sunlight even on cloudy days. Frequent rain shapes the look of the town’s trees and gardens.
These conditions affect how you plan your time outdoors and how the landscape looks.
UV Index and Sun Exposure
In September and October, the UV index often hits 10 to 12, which is very high to extreme. Even a short time outside exposes you to strong radiation.
By November, the index drops a little, but you still need to be careful. You should use broad-spectrum sunscreen, wear light but long clothing, and bring sunglasses with UV protection.
Midday hours, from 10 a.m. to 3 p.m., are the toughest for sun exposure. Cloud cover during the rainy season doesn’t cut the UV risk as much as you’d hope.
UV rays get through clouds, so you need sun protection even on overcast days. For beach and pool time, the sea temperature sits around 29°C (84°F), so swimming feels great.
Still, with the high UV index and warm water, it’s smart not to stay too long under direct sun.
Effects on Local Trees and Landscape
When September and October roll around, Hua Hin’s greenery really starts to pop. Rain trees, palms, and tropical hardwoods push out fresh growth and their canopies get noticeably denser. You’ll see the soil stay damp, which helps roadside plants look extra lush.
Sometimes by late October, temporary flooding hits certain spots, especially near parks that sit low or along the coast. Smaller ornamental trees can struggle a bit, but the bigger native ones seem to love it.
As November comes in and the rain slows down, the ground starts to dry up. Lawns and gardens don’t need as much attention as they did a few weeks earlier.
Rainy spells also mess with flowering patterns. Some tropical trees, like frangipani and golden shower trees, throw out fresh blooms after heavy downpours, bringing bursts of color to the streets and gardens. All this new growth and recovery gives Hua Hin its unique fall look.
