Gunma Prefecture

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

Cities: 28 Updated: 17 Jul, 18:14 Open-Meteo

A comparison of 28 towns in the Gunma 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
Ideal
60–79

40–59

20–39

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
