HOURLY BURN CONDITION MONITOR
YOUR BURN UNITS
Daylight Window

Forecast hours are included according to calculated local sunrise and sunset. Extensions are optional; the analysis never includes hours earlier than 1 a.m. or later than 11 p.m.

SunriseUp to 10 hours earlier*
SunsetUp to 10 hours later*

*The overall eligible range is capped at 1 a.m.–11 p.m. Hours outside the resulting window do not appear in the analysis.

Cloud Sync

Connect to an RxBurnScout sync server (a Cloudflare Worker) to sync your burn units across devices. Without this, data is stored locally in your browser only.

Data Management

Export your burn unit configurations as JSON for backup or transfer.

What RxBurnScout Does

A personal tool for individual land managers. You enter desired weather conditions for your burn unit(s). RxBurnScout highlights times when all those conditions will be met based on the 7-day National Weather Service forecast.

HOW IT WORKS

1. Configure burn units — Set a unit name and location, weather parameter ranges (wind speed, humidity, precipitation probability, temperature), and the minimum consecutive hours needed.

2. Fetch the NWS forecast — The app pulls hourly forecast data from the National Weather Service API for your unit's coordinates.

3. Hourly co-existence check — Each hour: do ALL parameters fall within your ranges simultaneously? No daily averaging, no percentage scoring. All or nothing.

4. Window detection — Consecutive all-pass hours meeting your minimum duration are flagged as potential burn windows.

This tool identifies potential burn windows — it does not tell you when to burn. The decision always belongs to the land manager.
DATA SOURCE & LIMITATIONS

Forecast data from the National Weather Service API (api.weather.gov). Free, public, no key required. The interactive map uses OpenStreetMap data. The selected point helps choose a forecast grid; it does not guarantee site-specific weather accuracy.
