Frost forecast
The original inspiration behind Climate Consulting was an area-specific frost forecast for the Marlborough and Waipara viticulture regions. The first forecasts commenced in September 2005 and modified versions are sent out each spring and autumn to a growing number of clients by email and txt. The forecasts include a detailed description of the local weather, including observations, as well as minimum temperature predictions for nine areas in Marlborough and two areas in Canterbury. The forecast uses atmospheric thickness levels to provide an extended outlook for the following 7 days.
The forecast season consists of two parts, spring and harvest; Spring commences in mid September and continues through the end of November and harvest commences mid March and continues through to the end of April. Annual subscriptions to the forecast (which includes both spring and autumn periods) is $650 + gst.
Forecasts are usually issued around 9am and updated if predicted conditions change considerably from those on the forecast. Amendments will also be issued if conditions change from “no frost” to a “frost” or “frost to no frost” scenarios. Updates are advised by txt to cell phones between 3 – 4 pm, however clients are welcome to call and talk through additional details for a specific site of concern.
Frost protection advice and wind machine placement
Decisions concerning frost protection need not be an anxious one. Stu has 8 years experience providing site specific frost protection information to vineyards and orchards in New Zealand and Australia. The most effective method of frost protection and correct placement can save clients substantial money.
The most successful frost mitigation systems are installed after onsite testing of inversion character and identification of local nocturnal wind drifts. Having a greater understanding of the local climate in which frost protection systems operate, will save hours of wasted time and energy. Onsite testing of climate parameters that govern the success or failure of frost protection systems, can be carried out quickly and effectively without great expense.

Climate Data Analysis
Climate data from temperature data loggers and weather stations can be quickly summarised into user friendly reports. Typical reporting may analyse growing degree days, frost risk, wind exposure and rain events. Comparisons can be made between long-term automatic weather stations or other sites of interest. The concise report formats are tailored for insurance purposes, banks, investors and seasonal vineyard/orchard summaries.
