n8n workflow for Indonesian weather alerts

What This Workflow Does

This automated system continuously monitors weather conditions across Indonesia by fetching data from BMKG (Indonesia's Meteorological, Climatological, and Geophysical Agency). When specified weather thresholds are met (like heavy rainfall or extreme temperatures), it instantly sends customized alerts to your Telegram account or group.

For businesses operating in Indonesia's tropical climate, sudden weather changes can significantly impact operations. This automation eliminates the need for manual weather checks, providing timely warnings that help you make proactive decisions about logistics, staffing, and safety protocols.

How It Works

1. Data Fetching from BMKG

The workflow regularly queries BMKG's public API to retrieve the latest weather data for your specified locations. It checks for updates every 30 minutes by default (configurable), ensuring you receive timely information without overloading the API.

2. Condition Analysis

Each weather update is analyzed against your predefined alert thresholds. The system can monitor multiple parameters simultaneously - rainfall intensity, temperature extremes, wind speed, and humidity levels - triggering alerts only when conditions meet your specific criteria.

3. Telegram Notification

When alert conditions are met, the workflow formats a detailed message with relevant weather data and sends it through Telegram's bot API. Notifications include the location, weather condition, severity level, and recommended actions if configured.

Who This Is For

This automation is particularly valuable for:

  • Agriculture businesses monitoring field conditions
  • Logistics companies routing deliveries around weather disruptions
  • Tourism operators managing outdoor activities
  • Event planners needing weather contingency plans
  • Local government agencies tracking regional conditions
  • Individuals who want personalized weather alerts

Frequently Asked Questions

Common questions about weather alert automation for Indonesia

Automated weather alerts provide real-time updates about changing conditions, helping businesses and individuals prepare for potential disruptions. For Indonesia's tropical climate with frequent weather changes, automation ensures you receive critical alerts without manually checking forecasts.

This is particularly valuable for agriculture, logistics, tourism, and event planning businesses that rely on accurate weather data. Unlike generic weather apps, you control exactly which conditions trigger alerts and how they're delivered.

  • Reduces response time to weather events
  • Customizable for specific business needs
  • Works with official BMKG data sources

BMKG (Badan Meteorologi, Klimatologi, dan Geofisika) is Indonesia's official meteorological agency, providing the most accurate and authoritative weather data for the region. Their API offers real-time updates on rainfall, temperature, humidity, and severe weather warnings.

Automating with BMKG data ensures you're working with government-certified information rather than third-party weather services that may not have localized accuracy. The data comes directly from BMKG's network of weather stations across the archipelago.

  • Official government weather data
  • Updated every 30 minutes
  • Covers all Indonesian regions

You can automate alerts for various weather conditions including heavy rainfall, extreme temperatures, high winds, and potential flooding. The system can be configured to monitor specific thresholds (e.g., rainfall above 50mm) or receive general forecasts.

Businesses often set up alerts for conditions that directly impact their operations, while individuals might prefer daily forecast summaries. The workflow supports multiple alert types in a single configuration, with different notification formats for each condition.

  • Severe weather warnings
  • Temperature thresholds
  • Rainfall accumulation alerts

Telegram's bot API allows automated messages to be sent directly to individuals or groups. Weather alerts appear as instant messages with formatted text, images, or even location maps. Unlike email, Telegram notifications are near-instantaneous and have high open rates.

Users can also interact with the bot to request current conditions or adjust alert preferences. The platform supports rich media, so alerts can include weather maps or radar images when relevant to the warning.

  • Instant push notifications
  • Supports multimedia content
  • Interactive bot capabilities

Yes, the automation can be configured to monitor specific cities, regencies, or coordinates across Indonesia. Businesses with multiple locations can set up separate alert channels for each site. The system supports monitoring up to 10 locations simultaneously.

You can prioritize alerts based on severity levels for each monitored area. For example, a logistics company might set stricter rainfall thresholds for mountainous routes compared to urban delivery areas.

  • City-level monitoring
  • Coordinate-based alerts
  • Multiple location support

Custom weather automation provides targeted alerts only for conditions that matter to you, reducing notification fatigue. Unlike generic apps, you control the thresholds, formats, and delivery methods. Businesses can integrate weather data with their internal systems.

Individuals can receive alerts tailored to their daily routines and specific concerns like allergies or outdoor activities. The system uses official BMKG data rather than global weather models that may be less accurate for specific Indonesian locations.
