Châteauguay Valley Weather August 20-26, 2023

The end of August continued close to normal for temperature, and believe it or not, dipped to below normal for precipitation. The regular showers and high levels of humidity made it seem like it was wetter than it actually was.

There was ‘only’ 16 mm of rain in the last week, bringing the month-to-date total to 64 mm in Ormstown, which is 20% below where it should be for this time of the month. The neighbouring Environment Canada weather stations (Saint-Anicet, Sainte-Anne-de-Bellevue and Saint-Clotilde) are showing an additional 20 mm of precipitation in their month-to-date tally but most of that increase comes from earlier in the month and not in the last week.

The forecast for the approaching week is more showers at the beginning and then a nice sunny spell extending through the Labour Day weekend – we can only hope!.

The average temperature for the month now stands at 19.4 degrees Celsius, almost exactly the same as the previous two weeks, and slightly below the normal for the whole month at 20.2 C. Daytime highs have been below average and nighttime lows slightly above average, a trend that is forecast to continue for the rest of the month and into September.

Following the average temperatures, the corn heat unit (CHU) count has been slowly falling behind normal. So far in August there have been 618 CHU, which is slightly lower than the prorated normal (644 CHU) for the same period. Normal CHU for August is 768 CHU so it is likely that the total will be 100 CHU below by the end of the month. Since the May 11th start date for the heat unit count, the total recorded so far is 2,456 CHU for the 2023 cropping season.
