THE smog which has been creating potentially lethal levels of pollution in the UK will go up a notch in Swansea Bay tomorrow.
Coastal areas will see an increase to level four on Government section Defra’s air pollution scale.
Four means ‘moderate’ and sparks the following advice from Defra: ‘Adults and children with lung problems, and adults with heart problems, who experience symptoms, should consider reducing strenuous physical activity, particularly outdoors.’
The smog is caused by pollution from the UK and Europe, along with dust from the Sahara Desert, coupled with south-easterly winds and other weather-related factors.
The Saharan dust first struck on Monday when it left a dirty residue on cars across Swansea Bay.
Large parts of England, particularly the south and east, have been experiencing very high levels of air pollution, leading to warnings not to exercise outdoors, even if you have generally good health.
Today Swansea Bay has been covered by a 3 - low pollution level.
But tomorrow, while most of Swansea Bay remains on a 3, Gower, particularly the coastal community, will see moderate (4) levels of pollution, along with Llanelli and coastal and inland parts of Carmarthenshire, through to eastern Pembrokeshire, including Tenby and Saundersfoot.
On Saturday, the far western tip of Gower, along with the Pembrey, Burry Port and Kidwelly areas of Carmarthenshire, and a similar area of Pembrokeshire, remain at a 4, while the rest of the region will experience a 3 - low pollution rating.
