Question 1

What is the sunniest time of year in Kyoto?

Accepted Answer

The sunniest time of year in Kyoto is the summer, with **July 2025 standing out as the single brightest month at 346.9 sunshine hours** — roughly 11.2 hours of sunshine per day.

Across 2025, Kyoto recorded 2,706.7 total sunshine hours. The summer months (June to August) alone delivered 888.7 hours, about 33% of the entire year's sunshine packed into one season. After July, the next brightest months were August (298.8 hours), May (252.7 hours), and September (251.5 hours), confirming that late spring through early autumn is consistently the brightest stretch in Kyoto.

By contrast, the darkest month was February 2025 with just 162.3 hours, and the deep-winter and early-spring months (January through March) all stayed below 177 hours.

There is an important trade-off to keep in mind. July's abundant sunshine in Kyoto comes alongside intense heat, with an average temperature of 29.7°C (85.5°F) and humidity above 70%, so the brightest days are also among the most sweltering. For travelers who want plenty of daylight without peak heat, May and September offer a sweet spot — both topped 250 sunshine hours in 2025 while staying noticeably milder than midsummer. If maximizing sunshine is the priority, plan a Kyoto visit for July; if you prefer bright but comfortable conditions, the shoulder months of late spring and early autumn are the better bet.

Question 2

Which season is the wettest in Kyoto?

Accepted Answer

Summer is the wettest season in Kyoto, with the meteorological summer of 2025 (June 1 to August 31) delivering about 566 mm (22.3 in) of rain — far more than any other season.

Across 2025, Kyoto's seasonal rainfall broke down as follows:

- **Summer (June–August):** 566 mm (22.3 in)
- **Spring (March–May):** 389 mm (15.3 in)
- **Autumn (September–November):** 338 mm (13.3 in)
- **Winter (January–February):** 112 mm (4.4 in)

Summer alone accounted for roughly 40% of Kyoto's full-year total of 1,405 mm (55.3 in). The single wettest month was June 2025, which saw 304 mm (12.0 in) of rain — the heart of Japan's "tsuyu" rainy season — paired with high humidity around 79% and a mean temperature of 24.2°C (75.6°F).

This rainfall pattern shapes how the season actually feels in Kyoto. The combination of heavy June rain and warm, humid summer air (averaging 27.9°C, or 82.3°F, from June to August) makes early summer the dampest, muggiest stretch of the year. If you want to avoid the wettest weather, the drier spring and late-autumn months are a more comfortable choice, while January and February stay notably dry at just over 100 mm combined.

Question 3

What were the temperature extremes in Kyoto in 2025?

Accepted Answer

Kyoto experienced a wide swing in temperatures during 2025, ranging from a scorching peak of 39.2°C (102.6°F) to a freezing low of -5.0°C (23.0°F). This gives the city an annual temperature range of 44.2°C (79.6°F) across the year.

The hottest day in Kyoto came on 31 August 2025, when the maximum temperature climbed to 39.2°C (102.6°F). At the other extreme, the coldest night arrived on 9 February 2025, with the temperature dropping to -5.0°C (23.0°F). Over the full year, Kyoto averaged a mild 16.7°C (62.1°F).

The summer heat was both intense and persistent. Kyoto recorded 95 days with highs of 30°C (86°F) or above, including 44 days that reached at least 35°C (95°F), the threshold Japan classifies as an extremely hot day. Winter brought a sharp contrast, with 42 days dipping to freezing or below.

For visitors, these figures show that Kyoto demands very different planning by season. The humid, blazing summers make midday sightseeing tiring and call for hydration and sun protection, while the frosty winter mornings warrant warm layers. Spring and autumn sit comfortably between these extremes, making them the most temperate times to explore the city in 2025.

Question 4

What is the weather like in Kyoto in August?

Accepted Answer

August is the hottest and most humid month in Kyoto, with hot, sticky days and very warm nights. In August 2025, the city recorded an average temperature of 29.9°C (85.8°F), making it the warmest month of the entire year.

During August 2025, daytime heat in Kyoto was intense, with the hottest day reaching 39.2°C (102.6°F). Even after dark there was little relief: the coolest night only dropped to 22.0°C (71.6°F), so warm "tropical nights" were the norm. Humidity averaged 72.3%, which made the heat feel even more oppressive.

The month was also bright and largely dry compared with early summer. Kyoto soaked up 298.8 hours of sunshine in August 2025, roughly 9.6 hours of sun per day, while rainfall totalled a moderate 119.9mm (4.7in). Winds were light, averaging just 5.8 km/h (3.6 mph), which did little to ease the muggy conditions.

For visitors, this means August in Kyoto calls for serious heat planning. Schedule temple visits and garden walks for the early morning, carry water, and reserve the hottest afternoon hours for air-conditioned museums, cafés, or indoor sightseeing. The bright skies are excellent for photography, but the combination of high temperatures and humidity makes lightweight clothing and frequent shade breaks essential for anyone exploring Kyoto on foot.

Question 5

What is the weather like in Kyoto in April?

Accepted Answer

Kyoto enjoys mild, pleasantly spring-like weather in April, with an average temperature of 14.4°C (57.9°F) in April 2025 — making it one of the most comfortable months to visit the city.

Throughout April 2025, daytime highs in Kyoto averaged 20.6°C (69.1°F), while nights cooled to an average low of 8.4°C (47.2°F). The month warmed noticeably as it progressed: the warmest day reached 27.5°C (81.5°F) on April 19, while the coldest night dipped to just 1.6°C (34.9°F) on April 5. Kyoto received 83.6mm (3.29 in) of rain across 10 wet days (1mm or more), so showers were occasional rather than constant.

April was also generously sunny, with 245.9 hours of sunshine — about 8.2 hours per day on average. Humidity sat at a moderate 72%, and winds were light at around 7.2 km/h (4.5 mph).

These conditions make April an excellent time to explore Kyoto's temples, gardens, and cherry-blossom viewing spots. Pack layers: comfortable T-shirt weather by mid-afternoon can turn chilly after sunset, especially in early April. With warm, sunny days, manageable rainfall, and gentle breezes, Kyoto in spring rewards outdoor sightseeing and long walks along the Philosopher's Path.
