Analyses of the climatic influences affecting growing conditions such as Temperature, Solar Radiation, Wind and Humidity. Weather analyses are based on regional data obtained from the California Irrigation Management Information Systems (CIMIS) Stations and only characterize general growing conditions for the region.
Regional temperatures tracked below 10 year averages with a slight increase in September. Similarly, 2011 was a significantly cooler year than 2010, 2009 and 2007. The warmer temperatures in July and September salvaged the vintage.
Solar radiation fell behind historical averages as well as levels seen in 2011 & 2010 and 2009 & 2007. Early season shortfalls were partially offset by late season modest but higher than average levels of sunlight.
Wind conditions in our otherwise windy region were considerably diminished as compared with previous averages compounding the challenges of decreased temperature and sunlight and increased humidity. April and May were the only months exhibiting near-average airflow.
Humidity levels were higher than average throughout the entire growing season. The average humidity level of 78.1% achieved in 2011 set a 10 year record high, exceeding the previous high set in 2005 and 2010 by 1.9%.
