Nagano Prefecture

Compare countries and cities by VanSky score and pick your next stop

Cities: 38 Updated: 19 Jul, 09:14 Open-Meteo

A comparison of 38 towns in the Nagano Prefecture region (Japan) by VanSky score — where it's most comfortable to stop on your trip right now.

The country score (0–100) is computed from all of its cities, not a single point. Cities are grouped into regions, and a region's score is the median of its cities so dense clusters don't outweigh sparse ones. Final score = 0.65 × “best areas” (80th percentile of regions) + 0.35 × “typical conditions” (median of regions), so one warm city can't push the whole country to 100. Each city's score blends warmth (feels-like), sun, rain and wind, adjusted for night temperature and, on the coast, the sea. Data: Open-Meteo, refreshed several times a day.

80–100

60–79

The scale above shows what share of the country's cities falls into each comfort band. “Best spot” is the most comfortable region or city this week; “typical conditions” is the median score across regions.

VanSky Index

A weather comfort index for travel: a 0–100 score. Recalculated daily from live weather data — temperature, rainfall, wind and sun.

80–100 Ideal
60–79 Comfortable
40–59 Acceptable
20–39 Challenging
0–19 Extreme

How it's calculated:

  • Thermal comfort 35% — temperature + humidity
  • Sunshine 25% — panel charge, mood; in heat the sun is no longer a bonus
  • Precipitation 25% — rain → muddy ground
  • Wind 15% — awning, driving, noise
  • Extremes override all: frost, heat, storm, downpour
  • Heat counts by feels-like temperature: at 32°+ the score can’t reach “Comfortable”, muggy nights lower it further
  • A dangerous day drags the week down: a storm or downpour in the forecast keeps the week from being “Comfortable”
  • Bonus: warm sea, high panel output
