Kota Kinabalu Weather in August

August: warm and very wet

August stays warm, with daytime highs around 29°C and nights near 25°C. The bigger factor is rain: showers fall on about 25 days, and the sky is often cloudy. Expect sticky afternoons and sudden downpours, not long stretches of bright beach weather.

You can still explore the Sabah State Museum or browse Gaya Street when the rain eases. Boat trips from Jesselton Point to the nearby islands may be less reliable in rough or rainy weather, so keep a flexible plan. For hikers, muddy trails and low cloud can make Mount Kinabalu views harder to come by.

National Day and local life

Malaysia's National Day falls on August 31. Kota Kinabalu may hold celebrations and a parade, though the programme can vary by year. It's a good chance to see local pride up close, especially around the city centre.

Families who enjoy indoor breaks between showers may find August easier than a full day of outdoor sightseeing.

Crowds and practical tips

August is generally a quieter, wetter time than the drier months, so the city can feel less crowded than during busier travel periods. You may also find better hotel rates than in the peak season, though prices vary by property and date. Rain can still disrupt island plans, so avoid building your whole trip around one boat day.

If you're heading to Tanjung Aru for sunset, check the clouds first; heavy cover can hide the view. On a wet afternoon, try a bowl of Sabah laksa at a Gaya Street café instead, then return to the waterfront if the sky clears.
