If you were looking for great summer weather in the province, Environment Canada says Greater Moncton and Southeast New Brunswick was the place to find it this year.
The average temperature for meteorological summer – June, July and August – was 18.1 C which is 0.7 degrees above normal.
The weather office says humidity was often low, overnight lows were comfortable but 8 days hit 30 C or higher compared to a typical 4 to 5.
The downside was a lack of precipitation with 155 mm of rain recorded which is 40 percent less than the summer average of 268 mm.

Thunderstorm activity was common throughout Southeast New Brunswick in June and all but ten days had at least a trace of rainfall.
But precipitation amounts were generally light in Greater Moncton except for two major rain events – 36.6 mm fell on 09 June along with a peak wind gust of 102 km/h and 21.2 mm fell on 24 June.
Temperatures were cool during the first week of the month with an overnight low dropping to the freezing point although frost was generally avoided thanks to cloudy skies.
Summer-like conditions arrived by mid-month and many daytime highs climbed well into the 20’s C and reached 30 C or higher three times.

An unstable air mass moved from west to east in New Brunswick producing severe thunderstorms bringing torrential rain, large hail and strong winds.
Environment Canada believes a severe thunderstorm formed near Doaktown and possibly spawned a tornado that moved into the Blackville area last night.
Golf ball size hail and damaging winds with gusts up to 100 km/h were recorded in the Plaster Rock area.
Southeast New Brunswick has seen an above average 18 days with thunderstorm activity this June and a severe thunderstorm watch was issued in the region this afternoon.

At least one New Brunswick location dropped to a new low on 06 June.
Environment Canada says Kouchibouguac National Park set a new cold record of -1.7 C which broke the old minimum of -1.1 C from 1958.
Greater Moncton managed to escape frost this week thanks to cloud cover although the thermometer fell to the freezing point tying a record low.
Following a brief period of very warm air, forecasters say temperatures will reach near seasonal values for the short term.

The last couple of days had near record lows in Greater Moncton with temperatures dropping to near the freezing point.
A low of 1.0 C at the airport on Monday was close to the 1947 record of 0.6 C while a low of 0.0 C on Tuesday tied the minimum from 1995.
Fortunately cloud cover prevented frost in most of New Brunswick but another risk is possible by early Wednesday.
Folklore suggests frost can be expected until the full moon in June which is this Friday the ninth.

Weather conditions have been cool and unsettled in the Maritimes over the past several days.
While driving in Nova Scotia on Friday, I encountered everything from clouds and heavy downpours to a clearing sky with bright sunshine to clouds and rain again.
On the way home to New Brunswick on Saturday, I encountered similar conditions.
In Greater Moncton today, the thermometer climbed to a daytime high of only 10.6 C under a dreary sky which is about 10 degrees below normal for early June.
Forecasters say warmer, more seasonal temperatures will return by Wednesday but not before a risk of frost in Southeast New Brunswick by early Tuesday.
The Weather Network has released its summer 2017 forecast covering June, July and August.
A changeable summer is expected across Atlantic Canada with extended periods of above seasonal and below seasonal weather.
The southern Maritimes which includes Greater Moncton and Southeast New Brunswick and possibly into southern Newfoundland have the best chance of seeing temperatures tip to the warm side of normal.
Meanwhile, cooler than normal temperatures are expected to be more persistent across eastern Labrador and northern Newfoundland.
Near normal rainfall is expected this summer except for western and northern New Brunswick.
There is the potential for a couple of systems to tap into subtropical or tropical moisture and bring above normal rainfall to parts of the region.

While it has been dry this summer in parts of New Brunswick, no where has it been drier in the Maritimes than in southwest Nova Scotia.
Meteorologists say while the jet stream normally flows through the middle of the region providing adequate amounts of rain, it was pushed farther north this summer due to the Bermuda High which has been northwest of its usual position.
As a result, rainfall in northern New Brunswick has been above average while southwest Nova Scotia has only received 32 percent of its normal summer precipitation.
For example, Yarmouth had 87 mm of rain during June, July and August which is well below the average of 268 mm.
Emergency management officials say at least 1,000 households have run out of water and bottled water donations from major retailers are being shipped to affected communities.

Spring turned out to be a rollercoaster ride in Southeast New Brunswick throughout the three month period with seemingly more clouds and rain than sun.
The trend continued almost until the first day of summer in Greater Moncton with consistent sun and warmth not until around the middle of the month.
June was actually about normal in temperature with slightly below normal precipitation – more than one third of the rainfall total fell in the last two days of the month.

The summer season has gotten off to a great start in Southeast New Brunswick with a fabulous first weekend filled with sunshine and warm temperatures.
Greater Moncton climbed to 27.5 C on Saturday and even warmer today at 29.0 C – just shy of the warmest 2016 high of 29.5 C from 31 May.
Kouchibouguac was the hotspot in the province at 33.2 C.
Even with this round of warm weather, June overall is still running about 1 C below normal compared to the 30-year average with only a few days left to go.
