The daily weather log
More than half the month passed with sunny days, and cool nights (3°) that kept the average temperature down. The 18th was the 34th day without 5 mm of rain.
A lot of rain then came into the region carried on easterly winds from the very warm sea. The coast had five days of heavy rain, causing severe flooding. Manilla had only three rain days, totalling less than 16 mm. At the same time, areas near Mungindi had twice as much. Instead of rain, Manilla got a week of humid overcast days and very warm nights (11°). Thick fog on the 29th did not lift until after 10 am.
Comparing May months
This month had normal temperatures, but it was cloudier than any May since 2001. There were seven mild frosts (normally six), but none was below zero in the screen.
(May 2007 was warm and humid; May 2006 was cool and remarkably sunny.)
The rainfall total (19.0 mm) was in the 34th percentile for the month. While this is below the May median (27 mm), it is well above the most common May reading (5 mm). The two-month total for April and May (73 mm) is on the 33rd percentile. The three-month total (81 mm) is worse: it is on the 14th percentile, but that is not a serious shortage. The four and five month rainfall totals have now fallen to 38th and 41st percentiles. Beyond that, totals are above the median for all periods up to 72 months, except for the 15-month total, which has now fallen to the 45th percentile.
