Reporting a wrong frost date

Corrections are the most useful thing you can send. It helps to include:

• your ZIP code, or a link to the page;
• what you see in practice (for example, "our last frost is usually mid-May, not late April") and how many years you've watched it;
• anything unusual about your spot, such as elevation, a valley, or being near a lake or the coast.

We check reports against nearby weather stations and fix data or matching problems in the next data update. See the methodology for how dates are calculated.
