Integrating AI with Open-Meteo API for Enhanced Weather Forecasting

AI Weather Forecasting is the integration of artificial intelligence with real-time weather APIs to deliver precise, contextual, and user-friendly predictions. By combining natural language input with automated API calls, businesses and developers can build smart assistants that provide personalized weather updates in seconds.

In this blog, we’ll walk through a complete use case: integrating AI with the Open-Meteo API inside an n8n workflow for interactive weather forecasting.

Workflow Execution Steps for AI Weather Forecasting

This AI-powered workflow demonstrates how to fetch city geolocation and weather forecast automatically using Open-Meteo API with AI agents.

1. User Interaction

The workflow starts when a user sends a chat message (e.g., “Weather Forecast for the Next 7 Days in São Paulo”) through the hosted chat interface.

2. Query Processing

The Generic AI Tool Agent analyzes the input, leveraging Chat Memory Buffer if available. It identifies that it needs to fetch geolocation data for the requested city.

3. Geolocation Lookup

The workflow invokes the geolocation tool, which makes an HTTP request to the Open-Meteo Geocoding API.

• API returns the latitude and longitude for São Paulo.

4. Weather Forecast Retrieval

With geolocation details, the workflow calls the weather forecast tool.

• Open-Meteo API provides 7-day weather forecast data.

5. Response Generation

The OpenAI Chat Model refines and formats the weather forecast into a user-friendly response.

• The final forecast is delivered back to the user in the chat interface.
