Strengths and weaknesses

Open-Meteo logoOpen-Meteo
  • +No API key or account required for non-commercial use, a single HTTP GET returns JSON
  • +Blends 30+ models from 15+ national weather services and auto-selects the best local high-res model per coordinate
  • +Exceptionally broad data: forecast, historical (1940-present), marine, air quality, solar/PV, ensemble, seasonal, flood, climate
  • –Model data only, no real station observations, so no validated actuals or hyperlocal radar nowcasting
  • –Free tier rate limits (600/min, 5k/hr, 10k/day) frustrate some developers with bursty workloads
  • –Commercial use legally requires a paid plan even at low volumes
WeatherAPI.com logoWeatherAPI.com
  • +Generous free tier (100K calls/month) plus a low $7 paid entry point, among the cheapest in the weather-API market
  • +Extremely clean, simple JSON responses that make first integration fast
  • +Single API key works across all endpoints and stays the same when you upgrade plans
  • –Reported uptime (~99.91-99.93%) sits below a guaranteed 99.9%+ and trails four-nines enterprise rivals
  • –Formal SLA is gated to the custom Enterprise tier only
  • –Occasional forecast inaccuracies and lighter hyperlocal/minute-level precision than heavier providers like OpenWeatherMap One Call 3.0
