Daily Weather Reports with OpenWeather API, Google Sheets, and Gmail
Daily Weather Reports with OpenWeather API, Google Sheets, and Gmail This workflow fetches real-time weather data from the OpenWeather API, stores it in a Google Sheet, formats it into a beautifully styled HTML report and emails it to recipients automatically every day at 10:00 AM. It helps teams track and monitor daily weather trends and optionally correlate them with energy production or field operations. Who’s it for? Renewable energy teams monitoring solar/wind energy output vs weather Facility or operations managers requiring daily climate updates Researchers or analysts logging environmental metrics Any team needing automated, daily weather reports by email How it works? The workflow begins with a Schedule Trigger set to run at 10:00 AM IST daily. It calls the OpenWeather API to fetch weather metrics for a predefined location. The data is then passed to a Google Sheets node named "Append Weather to Sheet", which stores all the key values into a structured spreadsheet. A Set or Function node generates a clean, styled HTML email using inline CSS and the weather values. Finally, a Gmail node sends this report to one or more recipients with a clear subject line and formatted body. How to set up? Create/Open your n8n instance (Cloud or Self-hosted). Connect the following credentials: Google Sheets (OAuth2) Gmail (OAuth2) Set your OpenWeather API key in the HTTP Request node (api.openweathermap.org). Replace latitude/longitude in the request URL as per your location. Link a Google Sheet and define the correct tab name and headers. Configure recipient email(s) in the Gmail node. Deploy the workflow and test. Requirements n8n account (self-hosted or cloud) OpenWeather API key (free or paid) Google account with access to: Google Sheets Gmail A valid Google Sheet created with the following headers (columns): Country Location Latitude Location Longitude Temperature (°C) Feels Like (°C) Min Temp (°C) Max Temp (°C) Humidity (%) Pressure (hPa) Sea Level (hPa) Ground Level (hPa) Visibility (m) Wind Speed (m/s) Wind Direction (°) Wind Gust (m/s) Cloudiness (%) Sunrise (UTC) Sunset (UTC) Date Time (UTC) How to customize? Change the scheduled time in the Schedule Trigger node. Modify the location coordinates in the OpenWeather API URL. Update the HTML template with different formatting or styling. Add a second email or sheet for energy output to correlate with weather. Extend the workflow with Slack, Notion, or Telegram alerts. Add‑ons Integrate with a solar energy API to track power production with weather. Post weather summaries to Notion, Slack or internal dashboards. Generate a visual chart in Google Sheets over time using the collected data. Trigger alerts when specific thresholds are exceeded (e.g., wind gust > 10 m/s). Use Case Examples Solar farm reporting**: Monitor daily weather impact on solar panel output. Logistics planning**: Notify teams of visibility or wind risks before dispatch. Site operations**: Send forecasts to maintenance or ground staff. Academic/weather logging**: Track atmospheric data over time. Common Troubleshooting | Issue | Possible Cause | Solution | | ------------------------------ | ---------------------------------------- | --------------------------------------------------------- | | Email not sent | Gmail credentials not connected properly | Reconnect Gmail account via n8n credential manager | | Weather data is missing fields | API response changed or API key invalid | Verify OpenWeather API key and URL format | | Google Sheet not updating | Incorrect spreadsheet ID or tab name | Double-check spreadsheet ID and sheet name in node | | HTML email renders incorrectly | Broken or missing tags in HTML | Test output HTML separately in browser/email preview tool | Need Help?
