Grass pollen still high

The high grass concentrations seen in the first half of October were repeated during this sampling week in response to a five day heat wave in Cape Town with temperatures above 30’C. Tree pollen is declining although pine pollen is still moderate. Pine is a weak allergen. Weed pollen is slowly increasing and includes English Plantain, goosefoot grass, erica and protea. Fungal spores were uniformly low.
