I found this interactive temperature map and it prompted a post to direct ATGA members to the GrowWIKI. (Prompt, prompt)
This only uses a selection of Capital Cities but it only takes a small bit of shifting to suggest that Manjimup 34°.24 is almost on the same latitude as Adelaide 34° 92. Concrete and traffic laden cities are different of course to nice green countryside. (Read the background in the box that pops up “What about…” to see the maps modelling). But given another 80 years most of our children will be living in major cities if the trends continue, so this may be just an idea of what your kids summer will be like while they’re waiting for the weekend to get back to that truffle paddock their parents left them.
It’s the winter temperature ranges we’re more sensitive to for truffle growing, we need cold hours to force the ripening and the WIKI has that data.
Below is our ‘ideal’ growing areas overlay-ed in green on an average winter temperature map from the Bureau of Meteorology.
As always, higher altitude changes suitability and coastal areas are often tempered by the sea mass (which means they are subject to oceans warming).
