The middle of May marks a weather transition in the Arroyo Grande Valley. The cold harsh winds of early spring give way to foggy mornings and gentle afternoon breezes typical of summer in this area. The vines are flowering and the potential crop for the season is largely determined at this time. Warm, sunny weather means that most berries will be pollinated, the clusters are full, and the crop will be average to above average. Rain or cool cloudy weather leads to poor pollination and a small crop. The weather has been dry since mid April and temperatures warmer than average, implying good pollination and full clusters. Since the number of clusters in the vineyard is higher than average, all indications are for a larger crop for the 2012 season.
