Winds aloft here tap the map

Tap or click anywhere on the map for the wind and temperature at every flight level, the tropopause and the freezing level at that spot.

Route winds simple guidance

Enter two airports, a cruise level and your true airspeed. The tool follows the great circle at the cruise level and adds up the wind along the way. Climb and descent are not modelled.

How good are these winds?

How to use this page two minutes

Pick a flight level (FL050 to FL450). The colours show the wind speed at that level; barbs show where it blows from and how strong it is. Each level button also shows the matching pressure level (FL180 ≈ 500 hPa, FL340 ≈ 250 hPa).
Switch the layer to see temperature, the difference from the standard atmosphere (ISA), the jet stream cores, the tropopause, the vertical wind shear (a clear-air turbulence clue) or the freezing level.
Slide the time bar through the forecast hours, or press play. Change the model to compare HRDPS, RDPS, RAP and ECMWF; when they disagree, confidence is lower.
Hover (or tap) anywhere for the values; a tap also fills the "winds aloft here" table for every level.
Route winds: enter two airports, a cruise level and your true airspeed for the average headwind or tailwind, the time it costs or saves, and how other levels compare.
Every "?" opens an explainer: plain words first, then the detail for forecasters and pilots who want it.

Everything here is computed by MeteoFrontier from raw model output. It is automated guidance: it is not an official forecast, it is not the NAV CANADA winds aloft product, and it is not for flight planning on its own.

Methods and sources

Built for every new model run from the model data MeteoFrontier already downloads: ECCC HRDPS (2.5 km, to 100 hPa) and RDPS (10 km), NOAA RAP (32 km) and the ECMWF IFS open data (25 km, to 200 hPa). Wind and temperature are interpolated (in the logarithm of pressure) to the exact pressure of each flight level in the ICAO standard atmosphere, then drawn on one grid about 30 km apart over all of Canada. Jet axes, the tropopause (WMO lapse-rate rule) and the lowest freezing level are worked out from the same profiles. No NAV CANADA product is used as an input.
