In addition, if the scale is enlarged which includes the position of a favourite, and the favourite is clicked in the menu, again the scale is changed. E.g. scale enlarged to 9 by zooming in, then favourite is selected, then windy changes the scale to 7. It's impossible to select your own view with windy overriding every setting one way or another.

I have a number of URLs saved for windy displays, such as this one:

https://www.windy.com/-Rain-thunder-rain?rain,-34.032,21.500,8,i:pressure,a:FFMFR.

However on loading this URL, the ,8, is always changed to ,5, causing the scale to be changed. It does not matter if the number is smaller (e.g. 4) or larger (e.g. 9), it is always changed on loading. This is a real nuisance as I specifically choose different scales for different purposes, and they are always overriden.

Found out how to change to feet clicking on the ribbon at the bottom of the screen !

Just noted that cloud tops are shown in feet, but cloud base in metres!! Can't see how to change this. Used to be both feet, so something has changed recently.

Thank you for taking the time to provide a detailed explanation.

In reality, would never use a single source in flight planning (I go IFR anyway), but I thought it was pleasantly absurd to put the problem in perspective :o))

Forecast for Friday, 16 Nov 11.00 am local time at S33°56'49", E22°26'38"

Cloud tops: 2300 ft
Cloud base: 4087 ft

Not quite certain what the optimum level for VFR flight would be ... :o)

Forecast for S34° E20.5° for 21-Dec-2017 at 10 am local time shows the following:
Cloud base = 17272 ft Cloud tops = 13000 ft.

Suggests the forecast model does not check for inconsistencies, leading to questionable reliability??

Nice and useful feature.

It would be enhanced if every isoline could be clearly labelled with its value. Currently, you can see a number of isolines but only one, or maybe none, are labelled, so the information is of little value. The greater the zoom value, the worse the problem.

Windy covers almost every meteorolgical event, including sea swell.

How about adding high and low tide tables to complete the picture?
