<![CDATA[Route planning temperature error]]>Have a look at this: https://on.windy.com/5hdrq set the start time to +2d at 05h00.

saying -100°C for the temp… and negative wind speeds.

Thanks for your help!

This was for a bike race on Saturday, and with a bit of work figured out the wind; the planning tool enabled some great tactical decisions and I came 16th in my category.

The problem seems to come from the backend:

Weird values. It is very intermittent though. Speed does not appear to play a role, rather the number of waypoints. Probably an interpolation problem of some sort.

Your topic is already in Bug Reports category. I don't think there is a specific tag.
I have addressed my previous post also to the developer of the Route Planner. We shall see..

@marekd

Yes, I can't explain these strange values.
Developers should have a look at it.

But still get crazy temperature and wind speeds

The point forecast looks reasonable and correct:

I have deleted one waypoint out of 2 (clicking the cross near waypoints that need to be cancelled). Then you can drag them to better match your forecast trip.

Hi,
It seems you have too many waypoints. By dividing their number by 2, the wind and temperature figures are more consistent.

Remember that the resolution of ECMWF model is 9km, so there is no real benefit in having very close waypoints to each others.
