The abrupt change of weather that the Cape has been experiencing has favoured the increase in fungal spores. Moist, cool days followed by warm dry weather has seen sharp increases in Alternaria, and Cladosporium concentrations. Grasses are low on days of rain becoming moderate on warm days. Weed levels are low, but Chenopodiaceae (fat hen) erica, English Plantain and dandelion are pollinating now. Tree levels have decreased to low levels but Cypress, pine, gum, olive, plane and oak are still present in the atmosphere in low concentrations.
