As of 2026, Yokohama in April averages a high of 19°C and low of 10°C with 125mm of rain over about 11 days. Daytime 18-20°C spring warmth, mornings and evenings 10°C — daily range is wide.

April is very good for Yokohama.
April is peak season — cherry-blossom finale (April 1-10) folds into spring proper, and it's Yokohama's best overall month. Daytime 19°C / 10°C lows mean wide daily range but otherwise comfortable spring weather. The first week brings full-bloom photos; the second week brings sakura-fubuki (petal blizzard) — arguably the most photogenic hanami window. Sankeien illumination and the Ookagawa River walk are the can't-miss spots.
After cherry blossoms, mid-April rolls into tulip and pansy season around Minato Mirai, while Yamashita Park's rose garden begins to open. Chinatown shifts to spring dessert menus. Late April adds a fresh dimension if you missed the cherry-blossom peak.

Cherry-blossom finale + spring full swing — April's second week is unbeatable
April Weather at a Glance
April averages 65°F / 19°C highs and 50°F / 10°C lows — spring is full speed. Daily range hits 8°C, so layered packing matters. 125mm rainfall arrives as quick spring showers rather than long stretches. Cherry blossoms peak April 1-10, transitioning to tulip and pansy season late April. Sunrise 5:15 AM, sunset 6:20 PM — 13 hours of daylight.
April Travel Advice
First-week hanami captures full bloom; the second week's petal-fall is dramatically more photogenic. Combine Minato Mirai + Sankeien + Ookagawa River into a single day. Early April still needs an extra cardigan in cold spells. Cedar-pollen allergy sufferers should pack masks + eye drops. The April 11-25 window dodges both cherry-blossom and Golden Week surges.
Flying In from Overseas
Golden Week (April 29-May 5) is Japan's biggest domestic-travel week — flights, hotels, and shinkansen all maxed out at +50-100%. Spring break in much of Asia and the West stacks demand. Flights from Seoul (2.5h) $500-1,000, Singapore (7h) $700-1,100, Sydney $900-1,500, San Francisco $1,100-1,700, London $1,100-1,700. April 11-25 is the year's best window.
April Pricing Trends
Business hotels $80-150/night April 11-25, $130-250 cherry-blossom/Golden Week. 4-star Minato Mirai $270-470/night during peak overlaps. Sankeien $6 entry. USD 1 ≈ JPY 148.

Yokohama in April — Full Picture
April is peak season — cherry-blossom finale (April 1-10) folds into spring proper, and it's Yokohama's best overall month. Daytime 19°C / 10°C lows mean wide daily range but otherwise comfortable spring weather. The first week brings full-bloom photos; the second week brings sakura-fubuki (petal blizzard) — arguably the most photogenic hanami window. Sankeien illumination and the Ookagawa River walk are the can't-miss spots.
After cherry blossoms, mid-April rolls into tulip and pansy season around Minato Mirai, while Yamashita Park's rose garden begins to open. Chinatown shifts to spring dessert menus. Late April adds a fresh dimension if you missed the cherry-blossom peak.
The price trap: cherry-blossom days (April 1-10) overlap into Golden Week (April 29-May 5), pushing flights to $600-1,200 and Minato Mirai 4-star hotels to $270-470/night. The sweet spot is April 11-25 — cherry-blossom tail end + tulips opening, hotels at normal levels, flights manageable. For most international travelers, April's second and third weeks are the year's best value-meets-experience window in Yokohama.
