AI Weather Forecasting Agent: n8n, OpenAI & Open-Meteo

Overview
Unlock Dynamic Weather Insights with this AI Agent
This n8n workflow acts as an intelligent Weather Forecasting AI Agent. It provides a chat interface where you can request weather forecasts in natural language (e.g., 'What's the 7-day forecast for London?'). The agent leverages OpenAI's language understanding to interpret your query, identify the city, and then intelligently uses two distinct tools in sequence: first, it fetches the city's geographic coordinates via the Open-Meteo geocoding API, and second, it uses these coordinates to retrieve a detailed weather forecast from the Open-Meteo forecast API. This showcases AI-driven automation for multi-step data retrieval and processing, all initiated by a simple chat message.
Key Features & Benefits
- Natural Language Queries: Interact with the agent via a simple chat interface to get weather information.
- AI-Powered Tool Orchestration: OpenAI intelligently determines the necessary steps, first geolocating the city and then fetching its weather forecast.
- Accurate Weather Data: Integrates with the Open-Meteo API for reliable and detailed weather forecasts (e.g., max temperature, precipitation).
- Conversational Memory: Remembers previous interactions within a session for a more natural conversation flow (via Langchain memory node).
- Extensible & Educational: Serves as a clear example of how to build AI agents that can use multiple tools/functions (Langchain HTTP Request Tools) to accomplish complex tasks based on user input.
Use Cases
- B2C e-commerce: Offer personalized travel/activity suggestions based on weather forecasts for customers planning trips or outdoor activities.
- B2B SaaS: Integrate dynamic weather data into logistics, agriculture tech, or event planning platforms for smarter operational decision-making.
- Solopreneurs & Founders: Quickly get detailed weather forecasts for business travel, client meetings, or outdoor event planning without manual API lookups.
- CTOs/Heads of Automation: Use as a blueprint for building more complex AI agents capable of multi-tool interactions and natural language understanding for various business automation needs.
Prerequisites
- An n8n instance (Cloud or self-hosted).
- OpenAI API Key with access to a suitable model (e.g., gpt-3.5-turbo, gpt-4).
Setup Instructions
- Download the n8n workflow JSON file.
- Import the workflow into your n8n instance.
- Configure the 'OpenAI Chat Model' node: select your OpenAI credential or enter your API Key.
- Ensure the 'When chat message received' (Chat Trigger) node is active. You can test using the n8n internal chat interface or note its public webhook URL to use a standalone chat page.
- The Open-Meteo API tools ('A tool for inputting the city and obtaining geolocation' and 'A tool to get the weather forecast based on geolocation') are pre-configured to use public API endpoints and do not require separate keys.
- Activate the workflow.
- Test by sending a message like 'Weather Forecast for the Next 7 Days in São Paulo' via the chat interface.
