Kota Kinabalu Weather in June

June weather

June feels warm, sticky and often grey in Kota Kinabalu. The high is 29°C, and humidity stays high. Rain falls on many days, so showers can interrupt plans, even when the morning looks clear.

You can still explore the Sabah State Museum, browse Gaya Street, or take a boat to Tunku Abdul Rahman Marine Park when the sea allows. Keep island trips flexible: rain and cloud can make a beach day less inviting. Long, exposed walks around the waterfront may feel uncomfortable in the humid air.

Events and crowds

Kaamatan, Sabah's harvest festival, is centred on May 30 and 31, so its main celebrations are usually over by June. Hari Raya Haji sometimes falls in June, but its date shifts each year. Local school holidays can also bring more Malaysian families to the islands and waterfront.

June can feel busier than quieter months, especially around island boat trips. Rooms and flights may cost more during school breaks, though this varies. February is the best month overall for weather, so June isn't the pick for a reliably sunny visit.

Families with young kids may prefer museum visits and short waterfront outings over a full day on the islands.

A useful local tip

For a rainy spell, head to the Sabah State Museum in Bukit Istana Lama, then try a bowl of tuaran mee, a local fried noodle dish, in town. It's a better change of pace than waiting out showers at a beach café.

If you're set on visiting the islands, ask your boat operator about sea conditions before leaving Jesselton Point. A flexible plan matters here: June brings about 260 mm of rain, and cloud cover is common. Keep an indoor stop in mind for the afternoon, when a passing shower can change your plans quickly.
