I’ve been involved in weather, data, and environmental science for over 30 years. I just wanted better answers to a simple question:

“How many chill hours are likely over the next week?”

If you grow fruit trees or vines, you already know the importance of winter chill accumulation. This is a quick and accessible way to see the projected chill hours by region — based on modelled temperature and automatically updated.

What These Maps Are:

• ✅ Based on GFS model temperature forecasts
• ✅ Accumulated forecast chill hours over 10 days
• ✅ Free and updated automatically daily
• ❌ No station correction or historical comparison
• ❌ Not a replacement for in-orchard monitoring or BoM forecasts

This is a standalone resource — designed to offer some guidance where little else exists. It won't be perfect, but it’s a start.
