Have you tried here: https://www.thebuddyforum.com/pokef...-com-locate-track-pokemon-near-pokemongo.html
Best I get is this, while its not live, it consistently is right predicting Pokemon nests: Global Nest Atlas | The Silph Road | Pokemon GO Nests
if you dont mind relocating, worldpokemap website is working nice with toronto and ottawa canada. Once you filter everything out to just the ones you want (lapras, snorlax, drantini, etc) to see its great. It autoupdates itself and scans the whole city by itself. You can stock up on them rare candies very fast.
