January – February
The terrace mirrors at their deepest, the Luoping canola building to bloom, the northwest cold and crystalline. The province's best winter fortnights — book lodges early.

When to go.
Yunnan runs all year — but each window owns different places. The honest map of what works when, from the flooded mirrors of winter to the monsoon's green season.

One province, four calendars.
Yunnan's size and vertical range mean there is no single best month — there are four regional calendars, and the best journeys build around one of them. The southeast is the winter destination (the terraces need water and cold dawns); the northwest is clearest from autumn into the winter high pressure; the tropical south runs a dry season from November to April; and the central plateau is mild all year with a summer wet spell.
The monsoon (July–August) is the only genuinely limiting season, and even then the limits are honest rather than absolute: high treks run with rain plans, the tea south is lush and dramatic, and photography shifts to the green season's clouds. This guide gives the month-by-month summary, and the regional guides and season board carry the detail.
The year at a glance.
What each month does best.
March – April
Canola peak, the Dai new year's water festival (13–15 April), first-flush tea picking, rhododendrons starting. The busiest spring in the south.
May – June
Rhododendrons on the ranges, young barley around Shangri-La, warm lakeside days, the red land's planting repaint. Rain builds late in the window.
July – August
Warm, wet and dramatic. High treks run with flex days and leech socks; the tea south is lush; mushroom season peaks. Fine travelling with honest expectations.
September – October
The whole province fires: harvest gold on the terraces before the flood, clear Meili skies, mushrooms finishing, the red land's second reset. The single best first-visit window.
November – December
The terraces flood again, the northwest's visibility season opens, the south turns dry. The connoisseur's month — quiet, cold-dawned and reliable.
Four calendars.
The regional summaries.
The northwest (gorge, Shangri-La, Meili)
Sep–Nov clearest; Nov–Mar crystalline; May–Jun green; Jul–Aug a rain lottery. Altitude nights are cold in every season.
The west (Dali, Nujiang, Tengchong)
The mildest region — all year works. Mar–Jun blue-lake best; the Nu valley road prefers the dry months; Tengchong's springs earn winter.
The south (Pu'er, Xishuangbanna)
Dry Nov–Apr (the high season); green May–Oct with afternoon storms. April means the water festival — book months ahead.
The southeast (terraces, canola, red land)
Nov–Apr is the window: mirrors, bloom, festivals. Sep–Oct gives the harvest gold. Jul–Aug is green and fine but not the postcard.
