NEWA historical data access

The NEWA website is popular because real-time weather data provide short-term risk assessments during the growing season. But, have you ever looked back and asked yourself what went right or wrong? NEWA tools can also be used to follow insect or disease risk historically through a period of time. You can access this feature using any model or tool available on the NEWA website.

Instructions

From the ‘Weather Data,’ ‘Pest Forecasts,’ or ‘Crop Management’ dropdown lists in the website navigation bar, select your model of interest.
 Select your pest or disease, State, and Weather station and historical Accumulation end date.
View the historical output.
 

NEWA historical data access from ‘Inactive’ Stations

Every once in a while, we get a question about historical data from an ‘inactive’ station, which is a NEWA location that no longer transmits to the website. Historical weather data can still be accessed using the hourly or daily weather summary tools.

Instructions

From the ‘Weather Data’ dropdown list in the website navigation bar, select Hourly Data or Daily Summary.
Scroll to the bottom of available weather stations and find a station of interest.
Choose a month and year from the past.
Get your report.
