October often felt like August in Greater Moncton with 12 days reaching daytime highs of 20 C or higher.

Environment Canada says only October 1913 was slightly warmer since records began in 1881.

Temperatures did fall below freezing on 7 days with some scattered frost but the month escaped a hard frost and vegetation continued to flourish.

Rainfall was more than 30 percent below normal in Southeast New Brunswick continuing a prolonged dry period which began in early summer.

Late October heat wave

Nine communities across New Brunswick set new record highs yesterday and the same will likely happen again today.

Greater Moncton was the warmest spot in the province climbing to 23.1 C which broke the old maximum temperature of 22.8 C from 1928.

Greenwood was among six communities in Nova Scotia breaking records with a high of 24.5 C.

Four records fell on Prince Edward Island including Charlottetown at 21.7 C.

Environment Canada says the Maritimes is enjoying a late October heat wave because the region is sandwiched between low pressure and high pressure allowing warm, southerly air to move northward.

Warm Thanksgiving weekend

The jet stream brought warm southerly air into the Maritimes allowing temperatures in Southeast New Brunswick to climb into the 20s this Thanksgiving weekend.

Environment Canada says Greater Moncton reached a daytime high of 20.2 C on 07 October, 23.7 C on 08 October (near the record of 23.9 C from 1970), and 22.9 C on 09 October.

Given the autumn warmth, I couldn’t resist a visit to Aboiteau Beach (and neither could a handful of others) which was near 24 C under a mostly cloudy sky and it was quite windy.

Greenwood, Nova Scotia was the hot spot in Canada hitting 26 C for two days in a row.

Harvest Moon

The almost Full Harvest Moon over Moncton, NB, 04 Oct 2017

Under a mostly cloudy sky, it was difficult to capture the Full Harvest Moon in most of Southeast New Brunswick but I did manage to get a shot last night.

The Harvest Moon derives its name from when farmers used the moon’s bright light to help them gather crops for winter.

The Harvest Moon is the full moon nearest to the autumnal equinox which occurred on 22 September.

Record highs in the Maritimes

Astronomical spring officially arrived almost three weeks ago but it finally arrived in the Maritimes today with record highs throughout the region.

In Greater Moncton, the temperature climbed to 17.3 C – the warmest high of 2017 – which surpassed the previous record of 15.6 C from 1962.

It hasn’t been this warm since 22 October when the thermometer reached 20.5 C.

The hot spot in New Brunswick was 17.7 C in Kouchibouguac, it reached 16.7 C in Stanhope, Prince Edward Island and 21.1 C in Greenwood, Nova Scotia.

The highest temperatures in Canada were found in Saskatchewan today with a high of 24 C in Regina.

2016 was warm in Greater Moncton

The average annual temperature for 2016 in Greater Moncton was 6.4 C which was one degree above the 1981-2010 period according to data from Environment Canada.

Precipitation was below normal with 995 mm recorded (1200 mm is average over the same thirty years) broken down as 689 mm of rain and 297 cm of snow.

The highest temperature of the year was 30.5 C on 28 July while the lowest was -22.1 C recorded on 17 December.

The growing season stretched from mid-May to early October which gave Moncton about 142 frost-free days, slightly higher than the average of 127.

October 2016 – Mild then cold

It’s not surprising the days gradually get cooler in October but it was a sudden change in Greater Moncton when temperatures went from mild to cold during the last week of the month.

A warm, humid daytime high of 20.5 C on 22 October will undoubtedly be the last time the thermometer climbs above 20 C in this calendar year.

Although a couple overnight lows fell below freezing early in the month, a hard frost was not reported until 27 October.

Almost 50 mm of rain fell on Thanksgiving weekend in Southeast New Brunswick – far less than other parts of the Maritimes such as Cape Breton Island with over 220 mm.

First snow flurries of the season!

The first snow flurries of the season were spotted in Greater Moncton early this morning and snow even covered the ground in northwestern New Brunswick.

The jet stream has dipped south of the Maritimes which has allowed cold air to seep in with below normal temperatures.

The daytime high in Moncton today was only 5.2 C which is below the average maximum of 10 C for late October.

Fall foliage past peak in N.B.


Fall colours in Centennial Park, Moncton, 16 Oct 2016 (Dearing)

Centennial Park in Moncton was alive with colour yesterday with many people including myself snapping pictures of the amazing fall foliage on display.

But I realized that the fall colours are now past peak with some maple trees almost bare of leaves.

Typically the foliage reaches its colour peak in Southeast New Brunswick by early to mid-October and then the leaves begin to drop.

It’s a beautiful but a sadly short-lived show.

Snowtober in Saskatchewan!

A storm being dubbed Snowtober – Snow in October – has dropped as much as 40 cm of snow on parts of Saskatchewan and Manitoba.

Saskatoon received about 20 cm of snow which broke a 100-year-old record yesterday of 5.6 cm while Cypress Hills Park got 40 cm.

Forecasters say the snow cover may stick around for a few days with single digit highs in the long range outlook.

The normal daytime high in Saskatoon for early October is 14 C.
