All 12 Months
| Month | Score | Note |
|---|---|---|
| January | 6.0/10 | January at Ziro: 4–16°C at 1780m, cold and empty. Apatani villages open but trails stiff with frost — shoulder month, not music-festival season. |
| February | 6.0/10 | Late winter, warming |
| March | 8.0/10 | March cracks Ziro wide open. Rhododendrons fire up across the hillsides, the valley greens overnight, and the Apatani rice terraces begin their annual cycle. |
| April | 10.0/10 | April in Ziro: 12–24°C, Apatani rice paddy terraces at planting stage, villages welcoming. Roads from Itanagar are clear; Ziro Music Festival is September, not now. |
| Mayviewing | 8.0/10 | May holds the tail end of Ziro's golden window. |
| June | 4.0/10 | Monsoon begins |
| July | 2.0/10 | Heavy monsoon |
| August | 4.0/10 | Monsoon continues |
| September | 8.0/10 | Post-monsoon + Ziro Festival |
| October | 10.0/10 | October is arguably Ziro's finest month. |
| November | 8.0/10 | November is October's quieter sibling. The valley holds its autumn color a bit longer, crowds thin out, and you get the clarity without the competition. |
| December | 6.0/10 | December settles Ziro into winter mode. The valley is stark and beautiful, village life turns inward, and the cold keeps all but the committed away. |
