The highest correlations with mean temperature of the monthly periods are shown. Correlation coefficients for all pollen season definitions were averaged. Correlations above |0.5| are significant with p < 0.001. Correlations for Taxus/Cupressaceae and Urticaceae are not significant. Months without highly significant correlations are not listed.
