The North Course is open for play all year, weather permitting. In the winter we rotate between playing temporary greens in the approaches and the regular greens. Traffic on completely frozen greens does cause damage but at an acceptable level so when temperatures are cold enough we will have pins in the regular greens.
However, the weather we are experiencing results in a freeze-thaw cycle, leaving the surface unfrozen above a frost layer below. If frozen greens thaw during the day, however, golfer traffic may cause shearing of the upper profile (the thawed layer) from the still frozen soil below, which could severely compromise turf health and future playability. As such, closing the greens on days when thawing is possible is recommended.
Direct wear injury, soil compaction and most importantly compromised playability are all a result of winter traffic on greens. Please follow the posted signs that will inform you if the temporary or regular greens are in play.
