Comparing March months

The average daily maximum temperature, at 31.8°, was the hottest of any March in this short record. It was almost the same as in each of the months of this summer, but not as high as that of last November (33.9°). The daily mean temperature (23.6°) was also the highest for March, just beating the 23.4° of March 2000. Night temperatures were normal, making the daily temperature range wider than normal. The mean early morning dew point of 8.3° was a record low value.
The total rainfall of 35.8 mm, while well below the average of 53 mm, is quite normal. It is in the 46th percentile: nearly half of all March totals were lower. Among rainfall totals for more than one month, there is little change. Again, the only serious shortage is in the 24-month total, which is now in the 5th percentile.
