The anticyclone currently sitting over France means little movement of air so pollen from the trees may cause problems, some cities have also seen pollution levels increase in recent days.
If you suffer from hay fever the RNSA website may prove a useful place to explore, for example there are historical records for towns and cities across France enabling you to spot when pollen levels are at their highest.
One feature of the RNSA website that could prove particularly useful is a weekly email service that allows you to choose up to three départements and get updates to your inbox about pollen level risks.
