Best use for travel intelligence

For travel decisions, weather APIs are most useful when they distinguish city backup days from exposed beach, boat, waterfall, road, and mountain plans.

What this changes for travelers

  • TMD: Rain, heat, storms, and warning context for exposed days.
  • Air4Thai: Outdoor comfort and smoke/AQI decisions.
  • GISTDA: Flood, fire, drought, satellite, and hazard layers.
  • Thaiwater / RID: Flood, river, rainfall, reservoir, and water-context checks.
  • NASA FIRMS / GDACS / USGS: Fire hotspots, disaster alerts, and earthquake context when local feeds are thin.

Best sources to start with

  • Best official weather source: Thai Meteorological Department (TMD) for forecasts, warnings, earthquakes, and weather data services.
  • Best air-quality source: Air4Thai for Thailand station AQI/PM2.5, with OpenAQ and WAQI/AQICN as useful global backups.
  • Best disaster/geospatial source: GISTDA disaster layers for floods, fires, PM2.5, rainfall, and satellite-backed hazard context.
  • Best hydrology source: Thaiwater/HII and Royal Irrigation Department feeds for rainfall, water levels, dams, and flood context.
  • Best global backup: NASA FIRMS for fire hotspots, USGS for earthquakes, GDACS for global disaster alerts, and Copernicus/ERA5 for climate baselines.
  • Best developer starting point: Start with data.go.th/GDC for discovery, then promote stable TMD, Air4Thai, GISTDA, Thaiwater, NASA FIRMS, and USGS endpoints into dedicated connectors.
Official / agency sources

14 of 48 sources look official or agency-backed.

API/feed candidates

31 sources expose API, feed, CKAN/DataStore, JSON, XML, or similar machine-readable access.

Near-real-time signals

29 sources have live, hourly, event-driven, warning, or frequent update language.

Developer note

Prefer warning feeds and structured observations over page scraping; cache aggressively because weather and disaster endpoints can throttle or change schemas.

Last checked and source confidence

Last checked: 2026-05-11.

Source confidence: This cluster is strongest when several sources describe the same traveler problem from different angles: official context, machine-readable feeds, and slower fallback documentation.
