Sandakan is part of Sabah's East Coast region. Like all of Sabah, it has a tropical climate — warm and humid year-round — with distinct wet and dry seasons that meaningfully affect your travel experience. Orangutans, sun bears, and colonial heritage.
Best Months to Visit Sandakan
The best time to visit Sandakan is Mar, Apr, May, Jul, Aug. These months bring drier weather, calmer seas (if coastal), better road conditions, and optimal visibility for outdoor activities.
Book accommodation in advance — especially around Malaysian school holidays (June–August) and long weekends. Rates can jump 30–50% during peak periods.
Months to Avoid
Try to avoid Nov, Dec if outdoor activities are a priority. This is when Sandakan typically sees heavier rainfall from the NE monsoon, which can affect road access, river conditions, and sea crossings.
Heavy rain doesn't make Sandakan off-limits — it just means flexibility. Rain often falls in afternoon bursts, leaving mornings clear. Prices drop and crowds thin out. Always check local conditions before travelling to remote areas.
For most visitors, Mar to Aug is the sweet spot — good weather without the July–August peak crowds. If flexibility allows, Apr gives you excellent conditions with fewer tourists and lower accommodation prices.
