April-blooming Deane’s wattle

After a cool wet week at the end of March, April began warm, especially at night. The night of the 5th, at 18.8°, was the second warmest April night. Rain fell overnight, and the dew point, 18.5°, was an April record. The third week was sunny but cool, and the fourth week nearly four degrees warmer than usual. The last day of the month was suddenly cold (16.9°) and overcast, with drizzle.Weather log April 2014

Comparing April months

The mean minimum temperature was a record 1.7° above normal for the month, warmer than in April 2005, and the mean maximum temperature was also slightly up. The subsoil, after more than two years above normal (by as much as 2.4° in winter 2013), finally cooled down in March and April.
Moisture was near normal, with low rainfall offset by cloudy skies.
Although the total rainfall of 13.0 mm was below the April average (40 mm), it was not unusually low but in the 28th percentile. Taking rainfall totals for more than one month, the greatest shortages are not serious (i.e. not below the 10th percentile). The nine month total (336 mm) is in the 14th percentile. Other totals have higher percentile values, and most totals for 30 months or more are above normal. Pools still survive in Greenhatch Creek.Climate April 2014

Three weeks of normal March weather were followed by six days that were cool, humid, overcast and rainy. While the wettest day had only 26.4 mm, the 14 rain days would be a record for March, but for the 16 rain days in March 1894. (Manilla never had a month with more rain days than June 1950, which had 18.)Weather log March 2014.

Comparing March months

Unlike recent arid months, March was near normal in day-time temperature, humidity and cloudiness. Nights were very warm, however .

The total rainfall of 101.6 mm is almost twice the March average of 53 mm, and in the 85th percentile. March has been wetter in nineteen years, including 2001 (103 mm) and 2007 (114 mm). Taking rainfall totals for more than one month, the greatest shortages are not serious (i.e. not below the 10th percentile). The twelve-month total (469 mm) is in the 14th percentile. Other totals have higher percentile values, and most totals for 30 months or more are above normal.

The daily weather logWeather log February 2014.

The month began sunny and dry, with extremely low humidity. The second week brought a warm spell, which became humid and cloudy, leading to rain. There were eight rain days, with 18.8 mm recorded on the 17th. The fourth week was fine, with normal temperatures.

Comparing February monthsClimate February 2014.

Like February 2011, this month was very warm, but not quite as warm as February 2006. February 2008 had been five degrees cooler, and February 2012 and 2013 also very cool.
The humidity, shown by early morning dew point, has fallen steadily for four February months. It was 15.6° in 2010, and is now a record low of 10.3°. February mean relative humidity values, which had been steady from 2006 to 2013, fell sharply to 2014: afternoon values fell from 31% to 16% and morning values from 80% to 58%.
The total rainfall of 37.4 mm is well below the February average of 67 mm and far below that for February 2012 (194 mm), the fifth wettest on record. This is the forty-fourth driest, and in the 35th percentile. Taking rainfall totals for more than one month, the greatest shortages are not serious (i.e. not below the 10th percentile). The two month total (39 mm) and the twelve-month total (452 mm) are both in the 12th percentile. Other totals have higher percentile values, and most totals for 30 months or more are above normal. Pools survive in Greenhatch Creek.

The daily weather logWeather log January 2014.

Two 21st century records were broken on the 3rd: the daily maximum was 43.7°, and the relative humidity fell to 2%. A west wind of 30 km/hr blew all that day. The early morning dew point on the 6th was a record January low of minus 3.3 degrees. A second warm spell came about the 15th. Subsoil temperature fell from high to normal during the month.
Rain of 1.8 mm was recorded on the 20th.

Comparing January monthsClimate January 2014.

As well as having almost no rain, this month had by far the lowest January dew point of the century: 6.9°, which is 7.3° below normal! Compared to January 2013, which was very hot, days were much the same (35.9°), but nights were cooler (18.5°). By contrast, January 2012 had been very cool and cloudy.
The total rainfall of 1.8 mm was the lowest January value in the 131-year record. The next lowest was 7 mm in January 1940.
Counting more than one month, the six-month rainfall total of 184 mm is the worst shortage at this time. It is in the 11th percentile of all six-monthly totals. However, such low totals usually come in August or September. It is rare for six-monthly totals as low as 184 mm to come in a summer month: it has happened only thirteen times. The lowest six-monthly total for a summer month was 145 mm for December 1946. Next was 151 mm for December 1951.

The month began cool, including two nights at 6.9°, the coldest December nights in this record. Later it became very warm, with one night of 24.0° and one day of 40.2°. Spells of sunny weather were separated by five rainy days.
The relative humidity on the afternoon of the 29th was the record low value of 4%, as on 10/1/13 and 13/8/13. (These values may be wrong. Few hygrometers can be read so low.)

Comparing December monthsClimate December 2013

This December was warm: just slightly cooler than December last year, and very much warmer than those of 2010 and 2011. Extremely dry air brought a new record low December mean morning dew point of 8.8°.
Subsoil temperature (25.7°) remained 1.5° above normal.
The total rainfall of 45.6 mm was in the 28th percentile, well below the average of 74 mm. However, there are still no serious shortages in rainfall totals for more than one month.

The Year 2013

This was one of the warmer years in the new century (but much cooler than 2009). It had the driest air, with a mean early morning dew point of 5.4°, 1.5° below average. The air has become drier each year since 2010.
