Windy launches Route Planner
Looks good. Hard to understand at first.
The new Distance planning tool appears to be only in Kilometers (?) Any boat or air journey need to be measured in Nautical Miles.
Two years ago I used the Windy distance tools to weather-route a friends yacht from Vancouver to UK via Panama. And all distances were then given as nM. Why the change?
I note that wind speeds are still given as Knots .-
A nautical mile is a unit of measurement used in both air and marine navigation, and for the definition of territorial waters. Historically, it was defined as one minute (1/60 of a degree) of latitude along any line of longitude. Today the international nautical mile is defined as exactly 1852 metres. This converts to about 1.15 imperial/US miles. The derived unit of speed is the knot, one nautical mile per hour.
See above this post from @Gkikas-LGPZ
Great Thanks. I thought it a bit strange.
@marekd One idea for future development: I am using your tool to plan sailing trips. It would be superior, if I could add properties of the current boat (speed in relation to wind angle and wind speed). So the tool could calculate, how fast the boat will be on every point of the journey and at what time wayponínts wíll be reached. :-) If that is working me as the Skipper (or the tool?) could check, what probably the fastest (ore most secure?) route will be ...
Thank you so far for that great development!
So what you want is a Routing App, like SailGrib or Squid Mobile apps or similar (they are several).
One of the problem is that Windy would have to include polar plot or polar diagram for many models of sailing boats, racing and pleasure boats, including for your boat otherwise you would be very disappointed.
What is a polar plot? (Click on Fig.1 and scroll)
This is a large library to update regularly.
Distance mesurements is only in meters/km. We, who navigate need distance measurement in nm (nautical miles), as before.

@marekd WONDERFUL! And very convenient when planning a flight - thanks! :-)
@stitch You are right, freezing altitude is wrong. Thank you for your repeated reportings. New fixed version will be available soon.

I love this new feature.
Is it possible that we could get a circle radius measurement tool too?
The Route Planner should have the capability to have speeds inserted for various legs/courses. This should inturn show the movement of the Ship/Boat over the legs with the forecast patterns.
Is it possible at your end (coding wise) to add the height of the terrain to the fcst freezing height which should then give the true freezing height abv sea level?
@stitch Sure, there is a picture from my local development IFR branch :-)
For Freezing Altitude, please consider ...
You could consider the possibility of uploading the polars of a boat so to perform weather routing. To include thresholds on wave height, minimum wind speed for motoring, maximum wind and gust speed and the possibility of evaluating several departure times would be also desirable. Congratulations for the great job done until now.
I'm loving it :)
Just had to get my head in the right space wrt ISA+/- . After a quick bit of Googling I can see the benefits of ISA esp with the tropopause highlighted and areas of potential instability/lower level inversions & cold/warm air advection. Neat!
Are the bottom 2 rows "cloud base height" & "cloud top height"?
I can't wait to get my hands on the Beta product......great work!!!!!!
Show also visibility along the route in the table.
@marekd Great tool! My recommendation: Let the user define somewhere in personal settings the boat speed in % of wind speed for e.g. 45°, 90°, and 135° plus maximum speed and have the tool calculating the progress of the boat along the route. Or, even better, build in the polar diagrams for some typical sailing yachts that the user can chose from in a drop down menu. The table should show the weather forecast along the route at the boat's calculated position while the time (and with it the weather forecast) is progressing. Let the user choose, if distance is indicated in kilometers or nautical miles.
Hello please is there a way to set the speed based on Ground Speed instead of wind speed? that would be useful for road planning! thanks!
