From November to February the rivers run clear, Lalakhal turns turquoise and the wetlands fill with birds.
Winter is the most comfortable season in Sylhet: dry roads, cool mornings and blue skies. It is also the busiest, so book stays early for December holidays.
What to see
- Lalakhal and Jaflong, when the water is clearest.
- Hakaluki Haor for migratory ducks and waders. Baikka Beel, a protected sanctuary in Hail Haor, has been officially closed to visitors since February 2025; ask in Sreemangal whether visitors are being allowed in.
- Lawachara and Satchari, when trails are dry and gibbons are active in the mornings.
- Shimul Bagan from about mid-February, in the Bangla months of Falgun and Chaitra, when the silk cotton trees bloom red.
Mornings can drop close to 10°C in the hills and on the water. Bring a warm layer for sunrise boat trips.
