Warm days, sticky air and little evening cooling

July is among Bali's cooler months, but that is relative: it still feels hot, particularly in humid air. Average daytime temperatures are 4.5°C above London's July high, so expect a noticeable change from home rather than fierce heat. Days reach 25°C about 96% of the time, while the share reaching 30°C is 0%. Humidity averages 81%, making loose, breathable clothing more useful than the modest temperature figures might suggest. Keep strenuous activity away from midday and leave room for shade breaks. Evenings offer limited cooling, with average lows of 23.6°C, so light nightwear and a comfortably cooled room are sensible priorities.

Allow for rain rather than expecting clear skies

Rain is the main compromise. July has about 13 rainy days and 43.0 mm of rain overall, so a completely dry holiday is not a sensible expectation. That does not mean those days are washouts, but it does make flexible outdoor plans and a light waterproof useful. Sunshine averages about 5.6 hours within 11.5 hours of daylight: there is scope for time in the sun, without expecting clear skies throughout the day. Keep sun protection handy even when conditions are mixed. July still sits among Bali's best-rated months, alongside August and September, so the judgement is positive if occasional wet weather will not spoil your trip.
