What is the worst time to visit Yokohama?
August is the lowest-scoring month (3/10, capped by extreme heat). Typical conditions: 25–31°C (13 rainy days).
Is Yokohama too hot in summer?
2 months (July, August) trip the heat deal-breaker in our scoring: apparent temperature crosses the comfort cap, so even with clear skies and low rain the score is held down. Plan around it if heat tolerance is low.
When are crowds lowest in Yokohama?
Search-interest seasonality (Google Trends 2021-2025) is lowest in May and peaks in November. Interest tracks both in-trip visitors and lead-time planners, so treat it as a "destination is on people's minds" signal rather than literal arrivals.
Which months in Yokohama have good weather but fewer tourists?
April (climate 7/10, crowd index 4) and May (climate 7/10, crowd index 0) — shoulder months with above-average climate and below-median search-interest. Often the best value-for-weather trade.
What is the UV index in Yokohama by month?
UV peaks at 8 (high) in August and is lowest in December at 2 (low). Monthly peak values: Jan 2, Feb 3, Mar 4, Apr 5, May 6, Jun 7, Jul 8, Aug 8, Sep 6, Oct 4, Nov 3, Dec 2.
What is the UV index in Yokohama in August?
August is the peak UV month in Yokohama, with a daily-peak UV index of 8 (high). Apply SPF 30+, wear sunglasses, and seek shade during midday hours.
How high can UV get in Yokohama on the sunniest days?
Most days look like the monthly average, but on the sunniest ~1 in 10 days UV climbs higher than the mean suggests. July is the worst case: typical days average UV 8 (high), but the top 10% of days reach UV 10 (very high) — and even higher. Months where the sunniest days routinely exceed the typical reading: March, April, May, June, July, August, September, October, November. Plan sun protection for the worst case, not the average.
Is air quality in Yokohama bad for travelers?
PM2.5 (fine-particle pollution) exceeds the WHO sensitive-group guideline (15 µg/m³) in 12 months: January, February, March, April, May, June, July, August, September, October, November, December. The worst month is December with a typical-day mean of 31 µg/m³ (unhealthy); on the worst 10% of days PM2.5 reaches 52 µg/m³ (hazardous) and higher. People with asthma, heart conditions, or sensitive children may want to avoid these months or limit outdoor activity. Source: CAMS via Open-Meteo.
