Centered on the needs of the agriculture community, we provide data and insight that goes beyond what is available from government weather agencies and the endless, advertisement-driven weather sites and apps.


Each and every forecast product is written by a human forecaster, not a computer algorithm.  We provide detailed five-day specifics for parameters that concern growers, and an insightful forecast discussion covering the next 6 to 15 days.  Weather websites that claim to show 30-45 day forecasts are simply driven by historical climatology, by which tactical farming decisions simply can not be made.


Since 1992, Terry Snow and the Weather Advisory Service Team have worked tirelessly to provide continuous support to our farmers, harvesters, PCA's, shippers and marketers.  We understand the inherent risk each commodity faces due to weather.  As we move into our 25th year, we proudly support over 270 agriculture businesses across the United States, Mexico and South America.



Just like every day is a work day for a farmer, we monitor weather conditions over our forecast areas every day of the year.  Our reports are issued via email and fax 6 days a week as standard procedure, and even 7 days a week when the weather situation calls for it, such as approaching showers or frost or freeze conditions during the critical vineyard budding period.

Being a permanent crop grower of vineyards and citrus, long range weather forecasting is crucial. As a citrus grower, preparing for a cold event takes a good week to be properly ready. Roland’s Central Coast forecast reports are by far the best available. Their 2 week forecasting gives me ample time and information I need for my decision making. Other services who predict 3-4 days out don’t cut it for me.
