 Comparing August months

While August 2008 had been the coolest, and August 2009 the warmest in the 21st century, nearly all averages this month were near normal. As exceptions, the daily maximum temperature was slightly low and the dew point (as in the two previous August months) was very low. Few mornings had dew on the grass.
The total rainfall of 54.4 mm is in the 75th percentile, well above the August average (40 mm). This rain also raised the rainfall totals for periods of more than one month, so that only the 18-month total of 691 mm now remains as a serious shortage (9th percentile).

Normal sunny July weather was broken by two rainy days in mid-month and another “rainy” day later. With the first rain there was a very warm night of 11.0°, at the time when nights are usually at their coldest (1.8°).
Late in the month days and nights were two degrees warmer than usual.Weather log July 2014

 Comparing July months

Average temperatures were normal, but the rainfall was low and the humidity (Dew Point) was very low. Recent July months have been quite different. Last July was very warm, July 2012 was very wet (ninth wettest), and July 2010 was very cloudy and wet, with warm nights. This month was not as dry as July 2011, which was not as dry as July in the drought year: 2002.
The total rainfall of 11.4 mm is in the 15th percentile. Taking rainfall totals for more than one month, the 4-month total of 83 mm is now a serious shortage (6th percentile). There are also serious shortages in the totals for 12 months (6th percentile), 15 months (8th percentile), and 18 months (9th percentile), Other totals have higher percentile values, and most totals for 36 months or more are above normal. In the very long term, the 30-year rainfall total (19,314 mm) has just fallen below the median for the first time since August 2010.
(Note. Figures for 30-year totals begin in 1914. The lowest 30-year total rainfall was 18,026 mm (601 mm per year) in November 1940; the highest was 21,031 mm (701 mm per year) in December 1978.)Climate July 2014

Most average values were near normal for June. However, the nights were warm, the daily temperature range narrow, and the skies cloudy. The month was not extremely wet and cloudy like June last year.
The total rainfall of 40.2 mm is in the 55th percentile, close to the average.. Taking rainfall totals for more than one month, only the 12-month and 15-month totals are serious shortages (7th percentile). The 3-month total (71 mm) is in the 12th percentile. Other totals have higher percentile values, and most totals for 36 months or more are above normal.

There were two severe cold spells in late March and early May. Days were several degrees colder than normal, and the daily temperature range was narrow. To compensate, there were three spells of very warm nights in early April, late April, and late May. The last of these also had warm days and lasted a fortnight.

Weather log autumn 2014

Rain fell on 23 days (twice the normal number), totalling 132.8 mm. Most of it (84.8 mm)  fell in the week beginning on the 24th of March. The autumn total is on the 125-year average, and in the 58th percentile.

In autumn seasons from 1999, this was equal warmest with 2007, but nights (11.8°) were by far the warmest, 1.3° above normal. The mean daily temperature range, at 14.1°, was the narrowest, and the percentage of cloudy days (48%) the highest. All these point to a more moist (maritime) climate than does the rainfall or the dew point.

Comparing May months

Air temperatures and the dew point were not far from normal. However, as the second graph shows, they are higher than in May months of recent years, such as 2012. Skies were extraordinarily cloudy, but the subsoil temperature was no longer high.
The total rainfall of 18.2 mm is in the 33rd percentile for May. While this is well below the long-term average of 41 mm, it is on the average for the last 15 years. Taking rainfall totals for more than one month, only the two-month total (31 mm) is a serious shortage (9th percentile). The fifteen-month total (585 mm) is in the 12th percentile. Other totals have higher percentile values, and most totals for 36 months or more are above normal. Pools still survive in Greenhatch Creek.
