August has continued on where July left off – hot and dry.
The average temperature for August is normally 20.2 degrees Celsius and has already reached 22.8 C after the first week. That’s the result of two days above 30 C and two more that were pretty close. The nighttime lows have also been warmer than normal, a trend that is forecast through the rest of the month.
Rainfall was almost non-existent in the past week, with just 0.8 millimetres recorded and most of that from two heavy early morning dews. This means it’s been almost three weeks since the last substantial rainfall in many locales – a dry stretch that will hopefully be brought to an end early in the coming week with 25 mm of rain in the forecast.
The corn heat units (CHU) followed the same trend as the average temperature and are finally moving ahead of the normal CHUs for this time of year. There were 163 CHU in the first week of August, with the prorated normal being approximately 148 CHU. The normal for the month is 768 CHU and, since May 12, total CHU accumulation is now 2056 CHU, which is also slightly ahead of what would be expected for the date (2010 CHU).
