Open-Meteo Weather Weekend Planner n8n Workflow (3-Day)

Plan your weekend with real weather—automatically (Open-Meteo + n8n, 3-day forecast)

This Open-Meteo Weather Weekend Planner n8n Workflow (3-Day) pulls a 3-day forecast for your location and turns it into practical indoor vs. outdoor weekend recommendations based on precipitation and WMO weather codes. Just run it manually in n8n and get a clean per-day plan.

What this workflow does

• Manual execution: The workflow starts when you manually trigger it in n8n.
• Fetch forecast from Open-Meteo: It requests a 3-day daily forecast (precipitation sum and weather code) using your configured latitude/longitude and timezone.
• Evaluate outdoor suitability: For each day, it determines whether conditions are suitable for outdoor plans using two thresholds:
  • Precipitation < 2 mm (default threshold)
  • WMO weather code < 60 (default cutoff)
• Generate recommendations: It outputs a per-day summary including conditions, precipitation, weather code, and a list of recommended indoor or outdoor activities based on the evaluation.

Use cases

• Plan a 3-day trip or local weekend: decide when parks, hikes, or outdoor events make sense.
• Family scheduling: quickly see which days are better for indoor activities if rain is likely.
• Automation engineers and SaaS operators: prototype weather-aware planning logic inside n8n using Open-Meteo.

Technical details

• Nodes / tech stack: manual trigger, HTTP Request, Code (threshold logic), Sticky Note (documentation).
• Open-Meteo integration: update the request URL with your coordinates and timezone (defaults to New York City: 40.7128, -74.0060).
• Customization: adjust the precipitation threshold and WMO weather code cutoff in the JavaScript code node; swap indoor/outdoor activity lists to match your group’s preferences.
