A Chiang Rai Day Trip in the Cool Season

November to February is the best stretch of the year for a Chiang Rai day trip from Chiang Mai: the rains have ended, average highs in Chiang Rai stay under 30 C from November to January, and the haze of the late dry season has not yet set in. In Chiang Rai the 30-year average is 20.6 mm of rain in December, on about two and a half days, with lows of 14.7 C (Thai Meteorological Department). The day to book is MONKEY TRAVEL ASIA’s Chiang Mai: Chiang Rai White, Blue and Red Temples and Karen Tribe, from US$29 on promotion, usually US$49 a person (checked November 2026), a 12.5-hour coach day that leaves at 7:00 AM.

On 26 November 2026, 20 January and 24 March 2027 the day cost US$34.06 a person without temple tickets and US$41.15 with them; the From figure in the booking box matched neither (checked November 2026). Free cancellation until 24 hours before.

The months, side by side

These are the Thai Meteorological Department’s averages for 1991 to 2020, its 30-year normals. Chiang Rai is the station nearest the temples; Chiang Mai is where the day starts and ends.

Thai Meteorological Department, climate normals 1991-2020, read November 2026. Averages, not a forecast.

February is drier still in Chiang Rai, 12.7 mm on under two days, and Chiang Mai’s average low that month is 16.8 C. November still has the odd shower. December and January are the coolest and driest months, with the lowest night-time temperatures of the year in both cities. By the afternoon, when the tour reaches the temples, it is warm enough for short sleeves.

Haze later in the dry season

The same records count the days with haze in Chiang Mai: 7.8 in November and 13.5 in December, then 18.7 in January, 22.1 in February and 26.8 in March, the most of any month, before 17.1 in April. Haze greys the views from the coach and from the hill at Huay Pla Kang. The figures count days on which haze was recorded, not how thick it was.

If the views matter to you, November and December are the months to go. The temples themselves are worth the day in any of them.

Dressing for a 7:00 AM coach

The coach leaves Chiang Mai at 7:00 AM, when December mornings average under 17 C in the city, and the coach is air-conditioned. A light jacket or long-sleeved layer does both jobs: the cold coach and the temples, which ask visitors to dress modestly. Bring comfortable shoes, a hat and sunscreen for the afternoon. Big bags stay behind, since suitcases and backpacks are not allowed on board.

The one fee that changed

Wat Rong Khun, the White Temple, raised its entry for foreign visitors from 100 to 200 baht on 1 January 2026. The temple’s announcement was reported by Chiang Mai News and by Khaosod English on 10 November 2025; entry stays free for Thais, anyone over 70 and children of 120 cm or less. Many older guides still give 100 baht. On the tour, the tickets option pays it for you; on the cheaper option you pay it at the gate.

The road and the length of the day

The day is long in any month. The option we read lasts 12.5 hours, and the tour runs 12 to 13.5 hours depending on the option. Two reviewers, on 2 and 6 November 2026, wrote about road works on the way, one of them about a bumpy ride; we found no notice of the works from the road authorities, so allow for them rather than count on them. One reviewer on 8 November was picked up at 7:00 AM and back at 7:30 PM.

How long the drive to Chiang Rai takes splits the hours between road and stops, and day tour or overnight is for anyone who would rather sleep in Chiang Rai.
