THE BEST TIME TO RIDE NORTHERN THAILAND

The short answer

The best time to ride Northern Thailand is mid-November to early February: cool, dry roads and the longest mountain views, with November the single best month. Late February to early April brings hazy days; June to October is the quiet, green, wetter season.

THE THREE SEASONS AT A GLANCE

Mid-November → early February

COOL-DRY SEASON

Dry roads, crisp mountain air, the longest views of the year. November is the single best month.

Best for: Anything — this is the window for the long tours.

Late February → April

HOT SEASON

Long warm days and dry roads. Field-burning haze on some days, so the big views aren't a promise. Songkran 13–15 April.

Best for: Shorter rides with early starts — a day loop, or a few days around Songkran.

May → October

GREEN SEASON

The hills turn green, the air is washed, and the roads are the quietest of the year. Mornings are for riding; afternoon rain is normal.

Best for: Flexible trips with spare days built in. Ask us about the roads the week you come.

NOVEMBER TO FEBRUARY, MONTH BY MONTH

NOVEMBER — THE BEST MONTH

The rains are done, the roads are dry and the air is at its clearest. Yi Peng and Loy Krathong, the lantern festival, fall on 24–26 November 2026 in Chiang Mai — ride either side of it and you get the festival too. From about mid-November the Bua Tong sunflowers bloom in Mae Hong Son province, up the spur road off Route 1263.

DECEMBER — PEAK SEASON

The busiest month in the hills. Pai peaks in December and the hill village of Ban Rak Thai books months ahead, so fixed dates are worth securing early. Cool mornings, dry roads, and mist in the valleys that lifts by mid-morning.

JANUARY — THE WINDOW FOR THE LONG ONES

Right inside the cool-dry season, with the dry mountain roads at their best. It is the month we point riders with two spare weeks at — the kind of trip the NBT Super Loop is built for. Roll over the high ridges after about 09:00 and you get the valleys with the morning mist just lifting off them.

FEBRUARY — COLD MORNINGS, OPEN ROADS

The first half of the month is still the cool season in full swing: cold mornings in the hills, clear ridgelines and every road open. Later in the month the hot season begins.

The rest of the year — March to October — is in the month list below, every month with its own reasons to ride.

QUESTIONS RIDERS ASK ABOUT TIMING

What is the best time to ride a motorcycle in Northern Thailand?

Mid-November to early February. It is the cool-dry season: dry roads, crisp mountain air and the longest views of the year, and November is the single best month. Late February to early April has hazy days from field burning, and June to October is the green season — quiet and lush, with afternoon rain.

When is the best time to ride the Mae Hong Son Loop?

November to early February, for dry roads on the mountain sections and clear views from the ridges. Cross the high ridges after about 09:00, when the morning fog has lifted. We run it outside the cool season too; in the green season we build in flexible days.

When is Yi Peng in 2026, and can I ride around it?

Yi Peng and Loy Krathong, the lantern festival, fall on 24–26 November 2026 in Chiang Mai — right at the start of the best riding season. Plenty of riders plan a tour either side of the festival so they get both. The city is busy that week, so it is worth booking early.

Do I need to book early for December and January?

Yes, if your dates are fixed. December and January are peak season: Pai peaks in December and Ban Rak Thai books months ahead. Our scheduled departures for the season are listed on this page and are open to joining riders.

Can I do a motorcycle tour in the rainy season?

Yes. June to October is the green season — lush valleys, waterfalls in full flow and almost no other riders. Mornings are the riding window and afternoons often bring rain, so we plan flexible days and decide each morning. Road status has no live feed, so ask us about the roads the week you come.

When are you thinking of coming?

Tap a month. We'll tell you what the road is like then — no form, no sign-up.

Every month in one list
January · Cool-dry season
January sits right inside the cool-dry season — dry roads, crisp mountain air and the longest views of the year. It is the month we point riders with two spare weeks at, because the dry mountain roads are at their very best. Roll over the high ridges after about 09:00 and you get the valleys below with the morning mist just lifting off them.
February · Cool-dry season
February opens with the best of the cool season still in full swing — cold mornings in the hills, clear ridgelines and every road open. The first half of the month is a favourite with riders who want the big views, and we plan every day of the trip around getting you onto the ridgelines at their best.
March · Hot season
March is the start of the hot season — long warm days, dry roads, and a relaxed pace built around early starts in the cool of the morning. It is also the tail of the field-burning months, so some days are hazy and the long valley views aren't a promise. What March does beautifully is a shorter, sharper ride: a day loop out of Chiang Mai through the hills, lunch somewhere shady, and back to town before the afternoon heat. Tell us your dates and we'll shape the route to that week.
April · Hot season · Songkran 13–15
April is Thailand at its most alive. Songkran falls on 13–15 April and turns every town into a joyful, friendly water fight — one of the great festival experiences anywhere in Asia. Pair a few days of riding either side of it with the celebrations in Chiang Mai, and you get the roads and the festival in one trip.
May · The first rains
The first rains arrive and the whole north turns green almost overnight. Mornings are the riding window, the air is freshly washed, and the roads are about as quiet as they ever get. Genuinely underrated: green hills, fresh air, and the switchbacks nearly to yourself.
June · Green season
Green season proper — lush jungle, washed air, and fewer riders out than almost any month of the year. Mornings are made for riding and afternoons for a long lunch while the rain passes. We build the trip with flexible days, so you ride the best of every morning.
July · Green season
The landscape at its most dramatic — deep green valleys, mist in the mountains and waterfalls in full flow. The 762 bends on the Pai road are a different ride entirely in the green season, and a guide riding in front of you makes every one of them a pleasure. Bring proper rain gear and enjoy a side of the north most visitors never see.
August · Green season
August is the north at its greenest, with rice fields glowing and the hills alive. It is a month for a relaxed trip with spare time built in — ride the mornings, take the long way when the weather is kind, and slow down for coffee in the hills. Tell us your dates and we will shape the trip around the best riding of each day.
September · Late green season
The rain eases through September and the rice terraces are as green as they get all year — some of the most beautiful riding scenery of the whole calendar. The roads are quiet and the countryside is at its most photogenic. A flexible trip gets the very best of it.
October · The golden shoulder
The rains fade through October, the hills are still green, and the roads are wonderfully empty — late October is one of the best-value weeks of the year to be on a bike here. It is a lovely time for the Pai road.
November · Cool-dry season · the best month
The cool-dry season opens around mid-November and this is the single best month of the year to ride Northern Thailand: fresh air, cool mornings, ridgelines you can see the whole way along. The Bua Tong sunflowers on Doi Mae U-Kho come out from about mid-month — up the spur road off Route 1263. And Yi Peng and Loy Krathong fall on 24–26 November 2026, the most magical week in Chiang Mai's year, when the city glows with lanterns and candlelit krathongs.
December · Cool-dry season · peak
Full cool-dry season — dry roads, long views, and crisp mountain air before the sun gets to work, so bring a warm layer for the early hours. Pai is at its liveliest in December and Ban Rak Thai is at its prettiest, which is exactly why rooms along the loop are worth booking early. Cross the high ridges after about 09:00 and the valleys open up below you.
