Hi @SpringGoat , this is not a bug. Please check this link: https://community.windy.com/topic/6995/the-forecast-changes-depending-on-the-zoom/2

Hi @helijoc , it's not a bug. We were discussing this issue some time ago: https://community.windy.com/topic/6995/the-forecast-changes-depending-on-the-zoom/2

@thebigmuzzy
There is no need to zoom to a level lesser than the model's resolution.
e.g. ECMWF has a resolution of 9 km.
Do not expect reliable changes in locations less than 9 km apart.
Only interpolated values.

but occurs at any point of Spain

Choose 10 days rain accumulation

@LLXC This has been a thing for a while. From what I understand, it is an issue with the interpolation. As you zoom in, the interpolation becomes a slightly higher resolution. I think it is a minor issue and don't think much of it. I've only noticed a difference of one or two units as I zoom in so it's not that big of a deal for me.

What I would recommend is zooming in as much as you like to get more accurate forecast readings.
