Piet Retief (eMkhondo) lies roughly 170 km south of Nelspruit. The Highveld plateau setting around Piet Retief (eMkhondo) means vehicle traffic and coal mining and power station operations are never far from the air quality picture, particularly once winter's still mornings set in. From spring onward, wind and rain reliably take over the job of clearing the air. Nearby towns on the plateau tend to see similar conditions.
