Dear Donna,
I did find this info which may be some help Siracusa Air Quality Index (AQI) and Italy Air Pollution | IQAir https://www.iqair.com/italy/sicily/siracusa But it does state that Syracuse doesn't have air sensor data. Nevertheless, the ratings for Syracuse today go from Good to moderate with increasing numbers. So there is some basis for making determinations. You can download an air quality app from here: https://www.iqair.com/us/air-quality-monitors/air-quality-app
I'm headed to Sicily on Sept 20. I'll arrive in Palermo, travel down the West Coast but intend to go to Syracuse. Can anyone tell me if the air quality in Syracuse has been impacted by Etna's eruptions? I have asthma so I've cancelled my visit to Taormina and Etna, But will stay in Syracuse for 10 days unless I can't breathe. I'd also like to visit Tindari if the ash doesn't reach there. If anyone is in Sicily now, could you let me know about volcanic ash impacts in Syrcuse, Ragusa, Noto, Tindari if you have any info or can give me a webpage that I can check? [I'm not interested in impacts in Catania since I've changed my departure From CAT to PMO instead]
I'll check back for answers. I leave Wednesday for Germany and will be on the road.
Thanks
