90% (early: most years still freeze after this)Apr 19
50% (the "average" last frost)May 1
10% (cautious: only 1 year in 10 freezes later)May 18

Most gardeners plant frost-tender crops (tomatoes, peppers, basil) after the 50% date, and closer to the 10% date for less risk.

n/a means NOAA did not publish a date at that threshold for this station (usually because it rarely gets that cold).
