July is fair for Yokohama.
July straddles the rainy-season exit and full-on summer. Average 29°C / 23°C, humidity 78%, rainfall 155mm. The first half is still tsuyu — heavy showers, sticky air, slower light. From around mid-July the rainy season lifts and summer arrives in earnest, with heatwave potential in late July.
The July headline is the Kanagawa Shimbun Fireworks Festival (mid-July) — around 6,000 shells launched over Minato Mirai harbor and Yamashita Park, one of Japan's three biggest fireworks events. Minato Mirai's night skyline + Tokyo Bay + fireworks makes for the year's best photography night. Hotels around Minato Mirai book up months ahead; harbor-view rooms triple-book — reserve 3 months out.

Tsuyu ends + summer arrives — top-three fireworks night
July Weather at a Glance
July averages 84°F / 29°C highs and 73°F / 23°C lows — tsuyu's end and summer's start. 155mm rainfall blends rainy-season tail with heatwave-risk afternoons. Sea-breeze cools Minato Mirai 1-2°C below inland Tokyo. UV index 10 — sun protection critical. Sunrise 4:35 AM, sunset 7:00 PM.
July Travel Advice
Late-July heat is exhausting after 1-2 hours outdoors. Schedule outdoor activities for morning (8-11) or evening (after 18:00); use midday for indoor stops (ramen museum, malls, art museums). The Kanagawa Shimbun Fireworks draw 500,000+ to Yamashita Park and Aka Renga — book a harbor-facing hotel room as your base, or reserve a dinner cruise.
Flying In from Overseas
Northern Hemisphere summer holiday opens — Europe + US outbound peaks build through July. Flights from Seoul (2.5h) $400-750, Singapore $500-900, Sydney (winter) $600-1,000, San Francisco $900-1,500, London $900-1,500. Fireworks weekend itself sees a regional flight + hotel surge.
July Pricing Trends
Business hotels $55-90/night, 4-star Minato Mirai $115-190/night, fireworks weekend +50-80%. Aka Renga Beer Garden ~$8-12 per beer. Kanagawa fireworks viewing free from Yamashita Park; reserved pier seats $30-80. USD 1 ≈ JPY 148.
