The temperature climbed to 30 C for three days in a row in Greater Moncton which is an unofficial heat wave since 32 C is the maximum by definition.
Those warm daytime highs, 30.4 C (19 July), 30.4 C (20 July) and 30.0 C (21 July), still haven’t eclipsed the season-to-date maximum of 30.8 C recorded on 11 June.
A cold front moved west to east through New Brunswick yesterday triggering scattered thunderstorms with heavy rain, gusty winds and even hail.
The heat and humidity have been replaced by a cooler, drier air mass with highs in the low 20’s C which is slightly below normal for late July.

For whatever reason, summer seems to go by faster than the other seasons and here we are already at the midway point of July.
After 16 days, Greater Moncton has been having a decent month with an average temperature of 19.3 C which is 0.5 degrees above normal.
Daytime highs have been warm but not hot with a peak of 29.4 C on 16 July while overnight lows have been mild except for a chilly low of 8.9 C on 05 July.
The only concern is a lack of rainfall.
The tally is 19.8 mm so far – less than a quarter of the monthly total – but keep in mind we are entering what is traditionally the driest period of the year in Southeast New Brunswick.
