Kyoto in July is Gion Matsuri month — 32°C / 90°F afternoons, 23°C / 73°F nights, 14 rain days. The most-cited Kyoto festival running all of July.
Kyoto in July is peak Japanese summer + Gion Matsuri. JMA data put afternoon highs at 32°C / 90°F and overnight lows at 23°C / 73°F with 14 rain days. Tsuyu typically ends mid-July; the second half of July is hot-and-humid Japanese summer (with afternoon thunderstorms but no sustained tsuyu rain). Gion Matsuri (the heritage 1,100-year-old festival, runs all of July at Yasaka Shrine and Gion district) — the most-cited Kyoto festival, with the Yamaboko Junko parade on July 17 (the heritage Yamaboko festival floats). Locals wear yukata (the lightweight summer kimono) at evening. The dressing rule lightens: lightweight cotton, mid-weight cardigan for AC, packable rain shell (late tsuyu in early July), slip-on canvas sneakers or jikatabi, modest cuts, hydration (heat-stroke risk — Japanese summers see hospitalization rates spike in late July-August). SOU SOU (Kyoto 2002), Issey Miyake heritage, Chiso (1555 kimono), Eirakuya (1615) continue. Skip leather — humidity still rots in early July.

Gion Matsuri (祇園祭) is the heritage 1,100-year-old Kyoto festival — runs all of July at Yasaka Shrine and Gion district. Founded 869 CE as a purification ritual against plague. The Yamaboko Junko parade on July 17 features 33 heritage Yamaboko floats (UNESCO Intangible Cultural Heritage); the floats are paraded through downtown Kyoto. Yoiyama (the festival eve, July 14-16) brings crowds to Shijo street with food stalls and lit floats. Pack: yukata (light summer kimono — rent locally for ~¥3,000-8,000); jikatabi or geta (wooden sandals); fan; reusable water bottle; cotton tee underneath.
Yes — yukata (light summer cotton kimono) is the traditional Gion Matsuri dress. Multiple rental shops in Gion and Shijo (Yumeyakata, Tomihiro, Kyoto Kimono Rental Wargo, Yumekoubou) offer yukata-and-styling for ~¥3,000-8,000 per day. Yukata is more practical than full kimono: lighter weight, simpler tying (or even pre-tied for tourists), easier walking. Wear with geta (wooden sandals) or jikatabi (SOU SOU rubber-soled split-toe). Pack cotton tee underneath; bring a folding fan; carry a small crossbody bag.
Kaiseki (Japanese multi-course haute cuisine) etiquette: arrive 5-10 minutes early; remove shoes at the entrance — wear socks without holes; sit seiza (kneeling) on tatami at traditional kaiseki ryokan, or at modern restaurant chairs; eat each course as served; don't mix dishes; finish all rice (leaving rice is considered wasteful); use the wet towel (oshibori) before the meal; thank the chef at the end with 'gochisousama'. Kaiseki dinner runs 7-15 courses; budget 2-3 hours. Pack: smart-casual minimum; slip-on shoes; socks. Hyotei (1837) is the most-cited heritage Kyoto kaiseki institution.
Yes — Mount Hiei (60 minutes northeast of Kyoto) is the heritage Tendai Buddhist mountain — the Enryaku-ji temple complex (UNESCO World Heritage, founded 788 CE) is the most-cited Tendai Buddhist site. The cable car + bus access is the standard tourist route. Pack: layered cotton/cool-wool blend, packable rain shell, structured walking shoes (the temple paths are uneven), sun hat, polarized sunglasses, water bottle, modest dress (covered shoulders and knees). Mount Hiei runs cooler than Kyoto by 4-6°C / 7-11°F at the summit.
