When you enable the optional location feature, we analyze your exact coordinates to detect microclimate factors specific to your garden:
- ✓ Elevation effects – Adjust frost dates for mountain or valley locations
- ✓ Water proximity – Detect nearby lakes, rivers, or coastlines that moderate temperature
- ✓ Urban heat islands – Account for city warming vs rural cooling effects
- ✓ Frost pocket detection – Identify cold-air settling areas in your area
Privacy First: Your coordinates are never stored long-term. We use them only to calculate the nearest ZIP code for zone accuracy and microclimate analysis during your specific request.
