Winston-Salem’s pollen seasons
The geography, climate and plants behind each season here, with a source for every fact.
Forsyth County runs a Rotorod pollen sampler at its Government Center building in downtown Winston-Salem.2 It samples every weekday during the local pollen season, and results are reported as pollen grains per cubic meter of air.2 A typical year at the city’s airport has about 228 days between the last spring freeze and the first fall freeze.1
The county’s pollen season normally begins in February, when cedar pollen first appears as temperatures warm.2 Oak pollen peaks in April with the highest densities of the year, and maple, pine and birch are also plentiful before tree pollen tapers off in early June.2 Grass pollen is most prominent in May and continues into September.2
During July, overall pollen levels are usually low.2 Ragweed pollen is very significant from late August through mid-September, and the non-native lacebark elm causes a spike in tree pollen during the same weeks.2 Common ragweed grows in all 100 North Carolina counties.3 The first hard frost of autumn typically ends the county’s pollen season in late October.2
