Lake Santa Croce is located in the southern part of the Alpago and is surrounded by the Alpago mountains to the north, the Cansiglio plateau to the east and southeast, and the Lapisina valley to the south.
Every afternoon, between spring and autumn, the lake is affected by thermal wind that blows from south to north with intensity ranging between 20 km/h and 40 km/h. This phenomenon is caused by the difference in temperature that is created between the mountains of Alpago and the underlying Venetian plain, and is also accentuated by the forced passage of the wind through the bottleneck in Val Lapisina to the north, not far from the village of Santa Croce.
