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?

1. Create/Open your n8n instance (Cloud or Self-hosted).
2. Connect the following credentials:
   • Google Sheets (OAuth2)
   • Gmail (OAuth2)
3. Set your OpenWeather API key in the HTTP Request node (api.openweathermap.org).
4. Replace latitude/longitude in the request URL as per your location.
5. Link a Google Sheet and define the correct tab name and headers.
6. Configure recipient email(s) in the Gmail node.
7. 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.
