Still not great period to travel, unless lot of rain. Nature is still very dry. But good news is that the raining season is coming. Month of May should be very nice and green!

March 2014

Very Hot, and dry, and hazy. Definitely not the best time to visit North Thailand. This year again, due to the forest fires, the haze as reached a dangerous level all over the North. Plane have been cancelled due to poor visibility. From Bangkok Post: "Chiang Mai: Thick haze blanketing the North forced the diversion of four flights en route to Chiang Mai airport yesterday. Visibility of less than 2,000m yesterday morning made landing in Chiang Mai impossible.

The Aerothai source said Chiang Mai was blanketed by more than 200 micrograms per cubic metre of fine particle dust for a second consecutive day yesterday.

The level of fine dust particles at provincial hall was measured at 282 micrograms per cubic metre yesterday, while Yupparaj School recorded 234. The province has recorded its worst air quality in five years due to the persistent haze."

We are still running some tours, but if you have the choice, I would recommend to wait until end of April. First rain and tropical storm prior the raining season are usually starting mid-April. Eventually after first rain the particles will be gone.

February 2014: Still cold at night, especially in the mountains for those sleeping in bamboo huts or basic accommodation. The day tremperatures are warm now, in the 28oC, but it is still great for cycling, especially in the morning. In Chiangmai, morning temperature in the 15oC. And make sure you take fleece for all trips.

January 2014: Still cold at night, especially in the mountains for those sleeping in bamboo huts or homestays during our trekking. Day temperature is good, in the 20oC's so it's perfect for cycling and trek. Make sure you take fleece and warm clothe if you are going on an overnight trip in the mountain. Happy New Year.

December 2013: Rain mid-month. Then a very cold weather for the last week of December and through the New Year.

November 2013: Few warnings of floods last month, but nothing in Chiangmai. Actually it was a very dry "raining season". Rain end of October will make our rafting season more fun. Trips are going out everyday with excellent weather and cool mornings.

October 2013: Announcement of floods, but nothing. Actually not much rain, except two last week of October due to typhoons. No flooding in North Thailand.

July 2013: After a dry month of June, finally the rain came. So far, a not so wet raining season, with river water levels still low. Our river trips are departing every day, while we are still trekking and cycling without getting all wet most days. July is a perfect month for Northern Thailand.

MARCH 2013: Huge tropical storm in Chiang Rai. Over 2000 houses damaged throughout the province. See news on the Bangkok Post online

CHIANG MAI, 26 March 2013: A smog covering most of northern Thailand will stop the annual exodus of Songkran holiday makers in its tracks unless nature comes to the rescue. Northern provinces are in the grip of a health threatening smog caused by the wholesale burning of paddy fields and forests across the Laos, Thailand and Myanmar. Provincial governors say they are speeding up efforts to fight the haze and are closely monitoring burning activities, but on the ground scenes in Chiang Mai, Mae Hong Son and Chiang Rai provinces are identical to last year when thousands of residents had to seek hospital treatment to combat respiratory ailments.

The haze has started as all the farmers are burning they dried rice fields in the plain, and as the valley is surrounded by mountains, the particles stagnate in the sky.
