The haze seen over some parts of the province in recent days has nothing to do with the temperature.
A northeasterly flow means temperatures in many areas are below normal, and while meteorologists are still waiting on confirmation, it appears as though those same winds could be carrying volcanic ash from Iceland with them.
Iceland has seen a recent increase in volcanic activity with the sudden eruption of Fagradalsfjall—a volcano just outside the capital of Reykjavik that has been dormant for hundreds of years.
Lava discharge from #Fagradalsfjall eruption has increased substanstially in May, weeks after it began. Surprising behaviour, says our expert team of geologists monitoring this extraordinary event, which makes for a spectacular show at night from my residence.

Meteorologist with the Gander Weather Office, Justin Boudreau says haze like that noticed in the St. John’s area in recent days is normally associated with warm weather, so they did a little investigating to see where it’s coming from.
They tracked the northeasterly flow to the region around Iceland. That, coupled with particulate readings that are slightly above normal, leads them to believe that what many are noticing is fine volcanic ash. He says it’s very diffuse and shouldn’t pose any harm to the public.
Boudreau says if their suspicions are right, then the air should clear up once the winds shift.
