No doubt the damage to the fruit is from leaves rubbing over the fruit during the strong winds. The leaves are receiving the same buffeting from the wind. Physical damage to the leaves is occurring due to abrasion and from petioles breaking. Also, moisture is being sucked out of the leaves faster than it can be replaced from the roots. Ideal relative humidity in the strawberry plant canopy is 70%. With strong wind the RH plumets. Trying to overcome this problem by running longer irrigation sets poses the risk of saturating the soil below 6 inches. This can lead to other problems. Several short irrigations that sum up to the total scheduled irrigation time for the day provide sufficient soil moisture for the plants, avoid saturation of the bottom of the root zone and marginally improves the microclimate around the stomata. This would be a really good time for micro sprinklers or misters.

This is great input Thom, thank you. I would think too that the CIMIS stations would adjust the evapotranspiration potential based on the windspeed. With you 100% on adjusting irrigation upward to account for the accelerated removal of water from the plants due to the wind.
