At a recent meeting of our local Seed Savers group, we talked a little about the various climate types across the area. In an effort to visualize this, ewe have analyzed our weather station data starlightcascade.ca\/weather<\/a> for two data points: light frost as -1C and heavy frost as -3C
\n\"\"<\/a>
\nFrost days at StarlightCascade Gardens just outside Yarker Ontario<\/p>\n

Two types, light frost low temperature of -1C and heavy frost low temperature of -3C.<\/p>\n

These define the first day of the fall with frost to the last day in the spring with frost, those temperatures which may kill off unprotected plants.<\/p>\n

A heavy frost is more likely to be a killing frost, whereas some plants may survive a light frost.<\/p>\n

The data is from our weather station

A closer look at the data shows more outliers in recent years, that is, the majority of the data readings are getting warmer, but there are more abnomalies later in the summer. We interpret these as a more energetic and chaotic climate with more variability.<\/p>\n","protected":false},"excerpt":{"rendered":"
