There is a hot humid sub-tropical climate in the south part of Bhutan. High temperatures there are whole year long. They can vary between 15-30 °C (60-86 °F). In the Central parts of the country it is a little bit cooler. Still it is hot enough during summer but it is much cooler during winters. Level of precipitations is not as high here in winter as at the south part of Bhutan. In northern areas of the country it is cold during the winter. And the higher it is the colder it is in the mountains whole year round.
