Tezu should be ideally visited during summer months (April to July). But September or October is also a good time as during this period, the temperature is moderate and the sky is clear for the perfect views and photography opportunity.
In summer time, which is between April and June, Tezu becomes quite warm. The average temperature ranges between 10 and 33 Degree Celsius making it a great time to be visited by the tourists.
The monsoon period is pleasant also which average temperature between 7 and 17 Degree Celsius. However, reaching Tezu via Assam can get little difficult because of the flood-like condition in this neighbouring state.
Winter period between December and February is quite appropriate to plan a holiday in Tezu. Where on the one side the temperature dips till -6 Degree Celsius (sometimes), the day time can be as warm as 32 Degree Celsius.
