Open-Meteo Global Weather and Climate Forecast Radar

Extract real-time weather observations and multi-day climate forecasts across global coordinates using Open-Meteo open weather datasets.

Features

• Extracts live observations including air temperature, apparent temperature, relative humidity, atmospheric pressure, and wind speed.
• Generates multi-day daily forecasts covering maximum and minimum temperatures, UV index peaks, precipitation sums, and wind gusts.
• Translates WMO weather interpretation codes into plain descriptive text labels.
• Supports metric and imperial unit conversions for temperature, precipitation, and wind velocity.
• Operates via public REST endpoints with zero API tokens and zero proxy overhead.
• Delivers clean records formatted for export to JSON, CSV, Excel, or automated analytics workflows.

Input parameters

• Latitude: Geographical coordinate between -90 and 90. Default is 40.7128.
• Longitude: Geographical coordinate between -180 and 180. Default is -74.0060.
• Forecast Days: Number of daily forecasts to retrieve, from 1 to 16 days. Default is 7.
• Temperature Unit: Scale for temperature values, choosing Celsius or Fahrenheit.
• Wind Speed Unit: Unit for wind speed, choosing km/h, m/s, mph, or knots.
• Precipitation Unit: Unit for rainfall volume, choosing millimeters or inches.
• Timezone: Coordinate based local detection (auto) or specific IANA timezone identifier.

Output dataset fields

Each dataset record represents either a current observation or a daily forecast with the following properties:

• recordType: Type of record (current_observation or daily_forecast).
• location: Object containing latitude, longitude, elevation in meters, and timezone metadata.
• observationTime / date: ISO formatted timestamp or calendar date.
• weatherCode: Official World Meteorological Organization (WMO) code integer.
• weatherCondition: Human-readable weather description (such as Clear sky, Slight rain, or Thunderstorm).
• temperature / tempMax / tempMin: Numerical temperature readings calibrated to selected units.
• apparentTemperature: Heat index and wind chill perceived temperature.
• relativeHumidityPercent: Current humidity percentage from 0 to 100.
• precipitationSum: Accumulated rainfall and precipitation amount.
• uvIndexMax: Maximum daily UV solar radiation index.
• windSpeed / windSpeedMax: Wind velocity values.
• windDirectionDegrees / windDirectionDominant: Compass orientation in degrees.
• sunrise / sunset: ISO timestamps for astronomical solar events.
• scrapedAt: UTC timestamp when the data was extracted.

Use cases

• Logistics planning: Monitor route conditions and storm alerts across distribution hubs.
• Agriculture operations: Track precipitation accumulations and frost risks for field management.
• Travel applications: Feed live destination forecasts into itinerary builders and trip calculators.
• Renewable energy analysis: Monitor solar irradiance and wind velocity indicators across geographical facilities.
