THE REAL POLLEN COUNT: Inland grass pollen levels continue to rise across Gauteng and the Free State

While last week's grass counts surged in several cities, this week two particular provinces continue with the high counts, making it particularly challenging for people with allergies.

Amid the highest recorded pollen counts in history, Health24 will be bringing you exclusive pollen count updates courtesy of the UCT Lung Institute's Allergy and Immunology Unit.

All you need to know about the ragweed invasion

Here are the major city updates for 30 January:

Overall, Trees, Grasses and Weeds all use the same values (grains per cubic metres of air).

Overall count is the daily average of pollen grains per cubic metres of air (trees plus grasses plus weeds)

As the pollen problem worsens, precise and expanded monitoring becomes even more essential. And here's how you can help.
