Kundasang weather and Mount Kinabalu climate by month

When to go

For the best odds of dry days, go in February or August², when rainfall in central Sabah is at its lowest. For a summit climb, aim for around April³.

Best months for each goal

• Climbing the summit: around April³. The operator Mount Kinabalu Climb Centre says the summit can be climbed at any time of year⁴.
• Clear views of the peaks: any month, as long as you look early in the morning⁵.
• Festivals: Pesta Kaamatan, the Kadazandusun harvest festival, runs throughout May, with the biggest celebrations on 30 and 31 May⁶. In 2026⁶ the main celebrations were held in Penampang.
• Mountain running: the Timpohon Run is on 17 October 2026⁷ and the Climbathon, a 24.5 km race, on 18 October 2026⁸, both at Kinabalu Park.
• Quieter stays: weekdays outside public and school holidays.

Months to avoid and why

• November and December: both bring rain³, the main reason climbers skip them.
• May and October: rainfall peaks in central Sabah². October also has the main rain peak on Sabah’s northwest coast².
• October to February: Wikivoyage says the northeast monsoon brings heavy rain to Borneo from October to February⁹.

Sources differ on how much this matters inland. MetMalaysia says hilly central Sabah, sheltered by mountain ranges, gets less rain than other regions, spread evenly through the year². Showers tend to be intense but short⁹, even in the rainy season.

Crowds, traffic and booking

Kundasang fills up on weekends, public holidays and school holidays¹, when almost all lodgings can be full. Kinabalu Park gets very full during spells of clear weather⁵. Check where to stay near Mount Kinabalu well before a holiday weekend.

In September 2026, the Daily Express reported Kundasang’s tourism association chairman saying congestion keeps recurring during school holidays, weekends and festive seasons¹⁰. The Kundasang to Ranau stretch is normally a 15-minute drive but can take up to two hours¹¹ at peak times.

Month by month

The months differ in rain, not warmth. MetMalaysia puts the yearly temperature swing across most of Malaysia at less than 2°C².

Temperatures from the park to the summit

Height sets the temperature here, not the month. The mountain’s climate runs from humid tropical at the base to alpine at the summit¹².

Sources differ on Kundasang’s height. Wikivoyage gives about 2,000 m¹, while Wikipedia gives almost 1,900 m, the highest settlement in Malaysia¹⁵. Ranau, the town below in the same district, has a tropical rainforest climate with heavy rain all year¹⁶.

Does it snow on Mount Kinabalu?

Very rarely. Snow has been recorded three times, in 1975, 1993 and 2022¹². Frost and ice occasionally form at the summit¹², and temperatures on the mountain can fall below 10°C⁹.

Most climbers spend the night at Laban Rata Resthouse, at 3,270 m¹², so pack warm layers for the hut and the summit.

Cloud, mist and rain through the day

The summit is usually covered in cloud⁵, so the time of day matters as much as the month.

• Early morning: the best time for a view⁵ of the peaks.
• Mid-morning: mist usually rolls in and hides the views⁵.
• On the drive up: Wikivoyage warns the weather turns first to mist, then to heavy rain¹ on the way to Kundasang.

The road from Kota Kinabalu takes about 2 hours via Tuaran¹⁷. The Kota Kinabalu to Kundasang travel times page covers the routes.

Closures

Summit closures follow the weather on the day, not the calendar.

The climb operator Mount Kinabalu Climb Centre says bad weather closes the summit on average about 15–20 times a year⁴. Mesilau has been shut since the earthquake of 5 June 2015¹², so climbs start from Timpohon Gate¹⁸.
