| With warm temperatures starting early this year with a prediction of a long hot summer, the sudden change to a warm, spring-like climate has set the wheels into motion for tree pollination. So barely a week into March and tree pollens have already risen to high values.
This outburst of pollen is coming 3-4 weeks earlier than last year.
In 2015, late season cold waves and snowstorms kept our trees in their seasonal slumber much longer than normal.
With an overall warm winter, the stage was set for an earlier and harsher than normal tree pollen season.
