This week started off pretty damp, delaying our greens aerification until Wednesday. The sand we use on the greens is kiln dried so it can be worked into the holes better. If we applied it on a rainy, or even foggy day, it would absorb the moisture and take much longer to fill the holes. We use regular sand on the tees and approaches so we were able to aerify those and topdress them without any issues. Also during the wet days, we deep tined the greens. The machine makes small 3/16" holes to a depth of about 7" in the greens. This promotes deep roots and superior drainage.
