September 2018 – Warm and wet

Warm, summer weather picked up in September where it left off in August in Southeast New Brunswick.

But the passage of a cold front marked a drastic temperature drop on the 18th and suddenly it felt like fall in Greater Moncton.

The thermometer continued to plunge and sank to -1.9°C on the 25th with light, scattered frost although most vegetation was spared severe damage.

Precipitation was actually above normal although heavy amounts fell in a handful of rainfalls.

A hot July also translated into a hot August in what has to be one of the warmest summers in Southeast New Brunswick since 1940.

In Greater Moncton, the thermometer climbed to 30°C or higher on 6 days during August and never dropped below 18°C during 9 overnights.

Fans, air conditioners and other cooling units sold out at stores across the region and many weren’t able to reorder more.

Although it seemed rather dry, rainfall was actually slightly above average thanks to a single rain event which delivered nearly 60 mm which is 60 percent of the monthly total.

Summer heat sizzles Europe

A warm air mass from north Africa has caused temperatures to skyrocket into the 40s C throughout the Iberian Peninsula challenging all-time heat records in Europe.

Lisbon, Portugal set a new maximum for 04 August at 44°C and even overnight lows are barely falling below 30°C.

Hundreds of firefighters are battling wildfires in the Algarve region and in neighbouring Spain.

The water in some rivers has become so overheated that fish are dying on a mass scale.

Forecasters say the heat is moving east and will affect France and Germany over the next few days.

The hottest temperature ever recorded in Europe is 48°C (118.4°F) set in Athens, Greece in July 1977.

Summer arrives!

The summer solstice officially arrived in New Brunswick at 7:07am ADT today.

This is the longest day of the year with 15 hours and 46 minutes of daylight in Moncton.

The sun is directly over the Tropic of Cancer and it will now begin moving south toward the equator which means days will be getting shorter again – by three seconds starting tomorrow.

As for summer weather predictions for the region, the Weather Network is suggesting July and August will have slightly above normal temperatures with high humidity.

Environment Canada believes there is an 80 percent chance of higher than average temperatures and a 40 percent chance of below normal precipitation.

TWN unveils summer forecast

Spring has sputtered in New Brunswick – it was nowhere to be found in March, finally appeared in late April and although May has had a few warm days, the month is still running slightly below normal in Greater Moncton.

So what about summer?

In its seasonal forecast, the Weather Network believes a cool June should give way to more consistent warm weather during July and August.

A humid summer is expected which may result in warmer than normal temperatures at night – overnight lows average about 12 C.

While periods of dry weather are expected, heavy showers and thunderstorms should bring rain totals to near normal for the season.

Having a heat wave in late September is unusual for Southeast New Brunswick but even more so is that the highest temperature of 2017 has occurred in early autumn.

The thermometer soared to 31.1 C yesterday (26 September) at the Greater Moncton International Airport which breaks the previous maximum of 29.6 C from 2007 and records date back to 1881.

The previous high for the year had been 30.6 C recorded on 04 August.

At least 10 other New Brunswick communities set new record highs yesterday including Fredericton at 32.8 C, Woodstock at 32.3 C and Bouctouche at 31.8 C.

A dry trend which began in late June continued during the month with less than 50 mm of rain falling in Greater Moncton.

Temperatures were above normal with daytime highs consistently in the high 20’s Celsius but a string of single digit overnight lows during the final week brought down the overall monthly average.
