Typical manifestations of the Guggifoehn
At the Jungfraujoch weather station (3,571 m a.s.l.), the Guggifoehn manifests as southeasterly winds, with gusts only 10–20 km/h higher than average winds. However, at the Lauberhorn weather station (2,315 m a.s.l.), the wind also comes from the southeast, and is on average of similar or slightly greater strength compared to the winds on the Jungfraujoch, but the gusts are significantly stronger – often 40–50 km/h higher than the average wind speed, highlighting the gustiness of the foehn.
For example, on 3 December 2022, during a classic Guggifoehn event, we see that the gusts recorded at the Lauberhorn weather station were significantly higher. Gusts on the Jungfraujoch peaked at 95 km/h, whereas the Lauberhorn station recorded gusts of up to 137 km/h.
In December 2008, the Lauberhorn station recorded an extraordinary gust of 252 km/h during a Guggifoehn event.
