Forecast

Access Jua's weather forecast data through our API or direct file access.

Overview

Jua offers two primary methods to access our weather forecasts, each optimized for different use cases:

API Access

  • Optimized for querying individual points or small sets of locations (up to 25 points)

  • Best for real-time applications requiring the latest forecast data

  • Only the most recent forecasts are available

  • Simpler integration with web and mobile applications

File Access

  • Optimized for bulk access over contiguous regions of locations

  • Ideal when you need hundreds, thousands, or all data points within a specific area

  • Provides access to both real-time and historic forecasts

  • Uses Zarr format, compatible with xarray for efficient data processing

Forecast Availability and Timing

Our forecasts are delivered 4 times per day per model. For a given forecast:

  • The first forecasted hour becomes available shortly after the dissemination start time

  • Subsequent hours are added as they are computed

  • Each forecast contains various weather parameters at different lead times

Choosing the Right Access Method

Use the API when:

  • You need data for specific points/locations

  • You're building a web or mobile application

  • You need real-time access to the latest forecasts

  • You're working with a small number of locations

Use the File Server when:

  • You need data for entire regions

  • You require access to historic forecasts

  • You're processing data in batch operations

  • You need hundreds or thousands of data points

Available Access Methods

  • API Access - Technical details for accessing forecast data via our REST API

  • File Access - Technical details for accessing forecast data files directly
