The following wind roses are based on data from the CAN407 CASTNET site. Annual and seasonal wind roses should represent canyon rim locations. Prevailing wind directions are predominantly east-southeasterly flow in the summer and more west-northwesterly flow in the other seasons, especially winter. Nighttime (0100 – 0600) and daytime (1300-1700) annual wind roses show a diurnal pattern. Daytime directions are mostly westerly (northwest to south-southwest)
