October 2026 outlook
Sabah and Sarawak should prepare for warm, humid conditions, frequent thunderstorms, and locally heavy rain during October 2026. Rainfall can vary sharply by district, so no statewide forecast guarantees conditions for a particular day.
Regional risks
- Sabah: West-coast, interior, and east-coast weather may differ; afternoon storms can disrupt road, island, and mountain plans.
- Sarawak: Kuching, central areas, and northern divisions may see separate storm patterns, with brief flooding possible where drainage is poor.
Practical planning
Schedule outdoor travel early, keep flexible indoor alternatives, and allow extra driving time. Carry rain protection, protect electronics, and avoid rivers, waterfalls, steep trails, or sea crossings when storms intensify. Coastal and highland conditions may change faster than city weather.
Check before departure
Use the latest weather forecast and warning map before travel, then recheck on the day. October outlooks describe broad tendencies, not precise timing; postpone exposed activities whenever lightning, rising water, rough seas, or evacuation advice appears.
