Everything with a date
Khao Phansa and Ok Phansa
เข้าพรรษา และออกพรรษา
Vassa, the rains retreat. It opens and closes with festivals, and it runs across exactly the months this circuit is quietest.
Loi Krathong and Yi Peng

The full moon of the twelfth lunar month, usually November. The river festival, and the northern lantern festival that shares its dates.

Songkran
สงกรานต์
The hottest days of the year, marked by pouring water. On a motorcycle this is a fact you plan around rather than a festival you attend.
The Akha Swing Festival
เทศกาลโล้ชิงช้าของชาวอาข่า
Yehkuja, the most important festival of the Akha year, held around a tall four-posted village swing. Worth timing a trip for — a different trip.

The rains
Takeaway · CC BY 3.0หน้าฝน
June to October. Afternoon rain most days rather than all-day rain, waterfalls running, rooms cheap, and PM2.5 at a tenth of its March figure.
