Farmers’ Almanac Predicts the First Frost Dates of 2024 for WA & OR

This isn't a fun one for me, however, it is informative. After all the excessive heat warnings we've had for the past several days, it seems only appropriate that we cool down for a spell, right? After some checking, we've learned that the Old Farmers' Almanac has already predicted first frost dates for Washington and Oregon.

It's beneficial for farmers and gardeners to know when frost is in the forecast. An entire crop can be ruined by a single frost in the PNW. A light freeze of 29-32 degrees will kill tender plants. A moderate freeze of 25-28 degrees can be destructive to vegetation.

How Does The Old Farmers' Almanac Make Its First Frost Date Predictions?

The Old Farmers' Almanac uses data gathered by NOAA National Centers for Environmental Information.

Note that frost dates are only an estimate based on historical climate data and are not set in stone. The probability of a frost occurring after the spring frost date or before the fall frost date is 30%, which means  there is still a chance of frost occurring before or after the given dates!
