Kew Mae Pan nature trail to reopen on November 1

The Kew Mae Pan nature trail is scheduled to reopen on November 1 after its rainy-season closure to allow the natural environment to recover.

The trail is one of Doi Inthanon’s main attractions, with visitors awaiting its reopening for the cool season. Tourists are already enjoying sunrise and mist at the Kew Mae Pan viewpoint.

Northern Thailand forecast to see less rain and cooler mornings

The Northern Meteorological Center forecasts declining rainfall across both the upper and lower North, with rain expected over 10% of the region and cooler conditions in the mornings.

The centre attributed the changing conditions to a high-pressure system, or cold air mass, covering the upper North, upper Northeast and South China Sea, bringing easterly winds over upper Thailand.

Temperatures in the upper North could fall by a further 1–2°C, the centre said. Its regional weather report separately put morning lows at 20–21°C.
