Best Overall Time (April to October)
April to June: Pleasant weather, clear skies, and blooming landscapes—ideal for trekking and festivals like Saga Dawa.
July to August: Warmest months, but also the rainy season (short showers). Great for high-altitude travel, though some roads may be affected.
September to October: Perfect autumn weather, stable conditions, and vibrant fall colors—best for photography and cultural tours.
For a Winter Travel (November to March)
Pros: Fewer tourists, lower prices, and stunning snow-capped mountain views.
Cons: Extremely cold (especially at night), some attractions may close, and high passes can be blocked by snow.
Best for: Travelers seeking solitude and unique winter landscapes.
For Festival Considerations
May-June: Saga Dawa Festival (holy month with pilgrimages).
February-March: Tibetan New Year (Losar)—colorful but very cold.
July-August: Shoton Festival (opera performances and giant thangka unveiling).
For the Consideration of Altitude & Regional Variations
Lhasa & Central Tibet: Best April-October.
Everest Base Camp: Optimal May-September (avoid heavy snow in winter).
Western Tibet (Mt. Kailash): Only accessible May-September due to extreme winter conditions.
Final Tip: For the best balance of weather, accessibility, and cultural experiences, late April to early June and September to October are the top choices!
