May is here which means it won’t be long before Jack Frost visits Atlantic Canada for the last time this spring.
Mid to late May is typically when the last frost arrives in Greater Moncton, early in the month for Halifax and late April for Yarmouth.
Early to mid June dates are normal for most of Newfoundland and Labrador.
Last year in New Brunswick and Nova Scotia, frost appeared as late as early June which proved disastrous for grape, blueberry and strawberry farmers.

The sun becomes an orange ball due to wildfire smoke, SE Calgary, AB, 14 Aug 2018 (Dearing)
British Columbia is more than 4,000 kilometres away from New Brunswick but that hasn’t stopped forest fire smoke from making its way across Canada.
On Friday afternoon, Environment Canada issued a special air quality statement: A plume of smoke from fires in Western Canada is moving at high altitude across the Maritimes today causing hazy skies and a reddish sun.
This smoke is not expected to reach the surface or affect air quality in our region and the plume will move off to the east tonight.
The British Columbia Wildfire Service says more than 600 fires are burning in the province with many regions still under air quality advisories.

Summer-like air enveloped the Maritime Provinces with new record high temperatures set in all three provinces yesterday.
Environment Canada says more than a dozen communities in New Brunswick hit new maximums for the date including St. Stephen at 34.0 C (hot spot in Canada), Fredericton at 33.0 C and both Woodstock and Edmundston at 32.0 C.
While the thermometer reached a record-breaking 30.5 C at the Greater Moncton International Airport, the overall 18 May record for Moncton is 31.7 C from 1918.
In Nova Scotia, new records were set in Greenwood and Kejimkujik Park at 32.0 C while Summerside, Prince Edward Island warmed up to 26.3 C.
Signs of spring, downtown Moncton, 10 April 2017 (Dearing)
For the first time this spring, temperatures in the Maritime Provinces climbed to 20 C and higher yesterday.
In Greater Moncton, the thermometer hit 20.6 C but wasn’t quite as warm as the record of 26.7 C from 1945.
Grand Manan Island was the hotspot in New Brunswick with a new record high of 20.8 C.
Several locations in Nova Scotia were also the warmest so far this season with 23.1 C recorded at Halifax Stanfield Airport although it was much cooler in downtown Halifax.
A new record was set in Kejimkujik Park at 25.8 C which was the hotspot in Canada.

An amazing shot of the Maritime Provinces captures a region covered in snow with Prince Edward Island almost in camouflage given the ice covered water surrounding it.
While the Northumberland Strait and the southern Gulf of St. Lawrence are mostly ice covered, the Bay of Fundy and the Atlantic Ocean are virtually ice-free.

A frost advisory is not too unusual for late May in New Brunswick but it is rare for the alert to be spread across all of the Maritime Provinces.
Environment Canada says even areas near the coast, which are typically milder overnight, will likely have frost tomorrow morning.
Farmers in the region are not too concerned since many are just now planting crops due to the cold, wet spring.
Garden and greenhouse centres are reporting a slow start thanks to the inclement weather.
