Chugoku: Current Temperature Ranking

View current temperature, provisional daily highs and lows, humidity, estimated WBGT and apparent temperature for AMeDAS stations across Japan on a map and in rankings. Filter by region, prefecture or station name and change the ranking order.

Estimated WBGT is calculated only from temperature and humidity. It does not include solar radiation or wind and may differ from official WBGT. Check public-agency information for important decisions.

Calculation and update details
  • Estimated WBGT and hazard levels use an independent simplified calculation and are not official heatstroke alerts.
  • Current temperatures update about every 10 minutes. A warning appears if updates are delayed by 20 minutes or more.
  • Daily highs and lows are provisional values accumulated from 10-minute temperatures and corrected with JMA values published about hourly.
  • Extremes or missing values between 10-minute observations may not be captured completely, so values can differ from finalized JMA data. Accumulation resets at midnight Japan time.

💡 About estimated WBGT and apparent temperature

Est. WBGT: This page shows a simplified heat-risk estimate calculated only from temperature and humidity. Solar radiation, radiant heat and wind are not included, so it may differ from official WBGT. Values of 28+ indicate severe caution and 31+ indicate danger.

Apparent temperature: A reference value calculated from temperature, relative humidity and wind speed with a Steadman outdoor-shade formula. It does not fully account for sun, clothing, activity or individual differences and does not guarantee how conditions will feel.

How to read and use KION

KION organizes Japan Meteorological Agency AMeDAS observations so you can quickly compare where it is hotter or colder across Japan. Along with current temperature, you can view provisional daily highs and lows, estimated WBGT and apparent temperature for the same station.

Choosing a ranking

Current uses the latest observed temperature, while High and Low show provisional daily extremes. WBGT and Apparent can be switched between highest-first and lowest-first. Filtering by prefecture, region or station name makes it easier to compare conditions around a destination.

Estimated WBGT and apparent temperature

Estimated WBGT is a simplified reference value calculated from the latest observed temperature and humidity. It is not official WBGT and does not include factors such as solar radiation or radiant heat. Apparent temperature uses the latest temperature, humidity and wind speed under an outdoor shaded-condition assumption. Neither value is a weather forecast.

Using nearby Cool Share spots

When you choose to use your location, KION can find the nearest observation station and nearby spots for the current season. By default, cooling shelters and cool spots are shown from April through September, and warm spots from October through March. Official facility-specific operating periods take priority when available. Coordinates and movement history are not stored. Facility information is based on public information from local authorities. Approximate facility locations are clearly marked as approximate. Information may change, so prioritize current on-site guidance and official information from the facility or municipality for opening hours, closures and conditions of use.

Updates and important notes

Current temperature is generally updated about every 10 minutes. Daily highs and lows are provisional values combining accumulated 10-minute observations with values published by the JMA, and missing data or delays can occur. For heat illness, severe weather or other safety decisions, prioritize the latest information from the JMA and other public authorities.
