More information for help determining your critical temperature.
Estimates minimum overnight temperature using Brunt Equation, and sunset air and dew point temperatures.

The Forecast Tracker plots the current and forecasted temperature on a graph to show how well these values "track" each other, and if critical levels are likely over the next 24 hours.

Evaporative cooling may result in plant damage when water is used for cold protection during dry windy conditions. Below is a table that categorizes evaporative cooling potential as "irrigation risk".
View irrigation risk criteria.
Station | Current Irrigation Risk | Current Air Temp ° F | Current Wet Bulb Temp ° F | Current Max Wind Speed mph |

Irrigation Risk | Time | Air Temp ° F | Wet Bulb Temp ° F | Wind Speed mph |

*Note: 'None' for Irrigation Risk indicates that Tair was at least 10 degrees F above your critical temperature, or at least 6 degrees above Twetbulb with little wind. In either case you should always use your best judgement to determine whether to irrigate.
Once the cutoff temperature has been reached, it is not necessary to continue irrigation until all ice has melted from the plant.

Please enter the specifications of your irrigation system and click [Create Schedule] to create a 2-week irrigation schedule.
-Find the current month along the left side of the table.
-Determine the point of interest in the growing season across the top of the table.*
-The intersection of month (vertical column) and plant growth stage (horizontal row) shows the average daily water use for your crop.
-Find your crop’s estimated rooting depth along the left side of the table.
-Find your crop’s average daily water usage (from the previous table) along the top.
-The intersection of rooting depth and average water usage shows the irrigation interval and application amount for your crop.**
*Week after planting is the least accurate method for estimating plant growth stage due to the effects of planting date and weather, so should be used with caution.
**Suggested irrigation schedules apply for the following conditions:
-Overhead irrigation systems with an application efficiency of 75%.
-Soil water holding capacity of 0.7 or 1.0 inches per foot.
-Available soil moisture depletion of 50%.
