Backyard Sap Tracker

Weather Setup

Choosing a weather provider

The app supports two weather data sources:

Select your provider in the settings screen. Both provide daily high and low temperatures used for sap flow prediction.

Setting your location

Enter your location in any of these formats:

The app uses this location solely to fetch local weather forecasts. GPS coordinates are not stored or shared beyond this purpose.

Temperature units

The app supports Fahrenheit and Celsius. It auto-detects the appropriate unit from your location but you can override this in settings.

Auto-fetch

When enabled, the app automatically fetches weather data when you open it. This requires an internet connection. Without auto-fetch, you can manually trigger a weather update from the dashboard.

Historical weather for past seasons

When you switch to a past season that has tap dates, the app automatically fetches historical weather data for any missing dates in that season’s range. This works even if some weather entries already exist for that season. Manual weather entries are preserved and never overwritten.

Sap flow prediction

Sap flow days are determined by temperature patterns: a freeze overnight (below 32F / 0C) followed by a thaw during the day. The app uses historical 5-year temperature averages to extend predictions out to 45 days beyond the current forecast.
