@admin The trouble is, in that 15km radius you have the beach and the hills, both cooler than the city, the southern suburbs which can also be cooler. I think your system also uses averages - the telltale sign is the decimal points in the max and min temps. I wonder if anyone can be that accurate in their forecasting, even BOM.

I'll unfollow as I have a good system that I use, and I live North of the city and outside the 15km zone, where it is hotter and drier than your target area.

I think this is a great service for many regions, especially those in rural areas. So well done with all the work. Maybe diverse metro areas are not so well covered.

(I just had a thought. When we live outside of the city centre, (in Adelaide, at least) we make adjustments on the city forecast - at my place it is 2 - 3 degrees hotter, down south perhaps 2-3 degrees or more cooler, in the hills it is cooler still. So if you average the temperatures, the result can be meaningless for everyone. Providing a forecast for the actual city area is possibly more useful for all, and people outside the city will make their adjustments. Just a thought.)

Thanks for listening, I appreciate it.
