Warm days, humid air and little cooling overnight

October feels hot without regularly reaching extreme temperatures: days reaching 30°C are unusual, but humidity of 85% can make the warmth feel more tiring than the thermometer suggests. Average nights stay around 24°C, so do not expect evenings to bring much relief. Pack loose, lightweight clothes and choose accommodation where you can cool down comfortably. Keep strenuous outdoor plans away from midday and leave room for breaks rather than filling every daylight hour. Compared with London's average October high of 14.6°C, Bali is a substantial step up in warmth. It suits travellers who enjoy warm evenings better than those who need cool conditions to sleep.

Plan for rain, not a washout

Rain is a regular consideration in October, but a rainy day does not necessarily mean a whole day indoors. With about 5.3 hours of sunshine out of 12.2 hours of daylight, there is scope for outdoor time, though clear skies should not be the expectation throughout your stay. Keep swimming and other outdoor plans movable, carry a light waterproof, and have an indoor alternative ready. Avoid assuming rain will arrive at a convenient time of day. October is a reasonable choice if warmth matters more than dependable sunshine; if weather is your deciding factor and your dates are flexible, August, September and July are stronger choices overall.
