Quick Answer
Spring and autumn, for comfortable temperatures: cherry blossoms usually peak in late March to early April, and the temple leaves color in November. June is hydrangea season, with rain and the biggest weekend crowds at Hasedera and Meigetsu-in.
Spring and autumn are the most comfortable seasons for walking between temples. June is the third option: hydrangea season, in the middle of the rainy season. Temperatures and rainfall below are 1991-2020 averages for Yokohama, the nearest major Japan Meteorological Agency station, about 15 km away.
Spring (March–May): Cherry Blossoms and Mild Weather
Cherry blossoms usually peak around the start of April: the agency's average full-bloom date for Yokohama is 1 April, and from 2021 to 2026 it fell between 25 March and 7 April. Tsurugaoka Hachimangu Shrine, the Dankazura approach and Genjiyama Park are the central spots.
Average daily highs climb from about 14°C (57°F) in March to 23°C (74°F) in May.
Summer (June–August): Hydrangeas, Rain and Coastal Heat
Hydrangeas peak in June: Hasedera's path (about 2,500 plants, with a separate timed ticket in the paid period) and Meigetsu-in in Kita-Kamakura. June is also the rainy season, with about 190 mm of rain on average.
July and August are hot and humid, with average daily highs of 29°C (85°F) and 31°C (88°F), which makes long walks between temples tiring. The draw then is the coast: Yuigahama Beach, Zaimokuza, and the Enoden's sea views west of Hase.
Autumn (September–November): Rain Early, Leaves Late
September and October have the highest average rainfall of the year, about 240 mm each, the tail of the typhoon season, so check the forecast before an early-autumn day trip. Autumn leaves usually color the Kita-Kamakura temples in November; Engaku-ji notes that the timing varies by year.
Average daily highs fall from 27°C (81°F) in September to 17°C (63°F) in November.
Winter (December–February): Dry, Clear and Cool
Average daily highs are about 10–13°C (50–55°F) and lows 3–5°C (37–41°F). December to February are the driest months, about 65 mm of rain each, and on clear days Mount Fuji is often visible from the coast west of Hase and from Enoshima.
Times to Avoid
- Golden Week (late April to early May): temples, beaches and the Enoden are at their most crowded.
- June weekends: Meigetsu-in and Hasedera draw large crowds. Hasedera's hydrangea path runs on limited timed tickets in the paid period (see the Hasedera guide), and Meigetsu-in's hydrangeas are usually best in mid-June.
- Obon (mid-August): heavier crowds at the beaches and central temples.
- Peak foliage weekends (mid-to-late November): Engaku-ji, Kencho-ji and other foliage spots are especially busy.
