July is deep in the wet season, one of the rainier months (around 190mm) with high humidity. Days stay around 32°C, and rain is frequent — usually heavy afternoon downpours, occasionally longer spells. The air is clean and the landscape vividly green.

It's a low-priced, low-crowd month with full waterfalls and green tea country, rewarding for travelers who don't mind planning around the rain. The trade-offs are the humidity, the chance of a rained-out day, and slippery or muddy rural roads. Mornings are generally the driest window for sightseeing.
Pack light clothing, dependable rain gear, and quick-dry shoes, and keep a flexible schedule. An umbrella plus a packable rain jacket covers most situations.
