Northern California – May 26, 2014

This report covers conditions and observations made between Monday, April 28 and Sunday, May 25, 2014. The next report is scheduled for Monday, June 30, 2014. However, in the event of any significant occurrences prior to that date, this site will be updated as soon as possible.

This report’s photos for the northern region present shots of the Nonpareil and Carmel in the Orland area of Glenn County, followed by a view of the Monterey in the Williams area of Colusa County.

Daily maximum temperatures during the period exhibited a cyclic pattern, rising above and falling below seasonal normal levels in weekly succession. Daily high readings peaked in the lower 90’s in the period’s opening days, at mid-month and finally as the period concluded, with readings rising only into the low to mid 70’s at the low point of each cycle. Meanwhile, morning low temperatures exhibited a more stable pattern, remaining in the mid 40’s to lower 50’s throughout the period.

Several low pressure systems spiraled over the state during the period, casting scattered showers over the region. Official rainfall totals in areas receiving precipitation ranged from trace amounts to nearly one inch, which was reported in Butte and Tehama Counties. Observers are reporting that while winds have generally been lighter than last year, winds speeds in the teens and twenties have not been uncommon.

Crop development continues in the Sacramento Valley at a strong and slightly accelerated pace. Observers are reporting that kernels of all varieties have now become fully solidified, or nearly so, leading many believe that the crop maturity is running approximately one week ahead of last year. However, this will not be confirmed until the first hulls of the Nonpareil begin to split. This is expected to occur along the west side of the region at the end of June or first days of July.

Water is on the minds of all in the region. Warming temperatures and windy conditions have moved growers into a summer-time mindset as they monitor moisture usage and schedule irrigations to meet the tree’s requirements. Those sourcing water from privately owned wells are hoping that they will be able to make it through the growing season.

In addition to providing water, growers have also been quite busy managing fertilizer requirements and monitoring pest populations within the orchards. Observers are reporting that the orchards are in generally good condition with few disease issues. Growers are monitoring trap catches of Navel Orange Worm and Peach Twig Borer and will time any required treatments to the most susceptible stage of the insect’s development.
