The weather pattern for both May and June was very similar with long, warm dry spells broken up by periods of heavy rain. However, both months received below average rainfall, and up until the 122.5 mm of rain we received between the 18^th and 23^rd of July the levels of all of the dams were lower than normal for this time of year. That all changed when all of the dams virtually filled over the corresponding period. The level of the main dam is approximately 1 metre below the spillway and I am now fairly confident that it will be full before the end of August given that the long term forecast for the next three is for above average rainfall.  Groundwater levels are now at the point where any further rainfall that we receive will be captured through the drainage system and discharged into the dams.

The 200.5 mm of rain that we received over the past month has meant that this July has been our wettest since 1996. As can be seen from the chart below, the past three months have also been significantly warmer than average and this has enabled us to spend a larger proportion of staff time on course presentation than normal and this is noticeable in the general condition of the course. The fairways, in particular are as dense and green as they have ever been for July.

The Start of the Winter Rains?

The much cooler temperatures and the 50mm of rain of the past few days is hopefully the start of our normal winter weather pattern. We are currently sitting at @100mm of rain less than our average for this time of year, this obviously means that we need above average winter rains to recharge the bore aquifers and refill our dams in preparation for next summer.

The rain we have recieved has thouroughly washed the recent fairway gypsum application into the profile. Greens have received an application of fungicide to target an outbreak of Dollar spot and Anthracnose that has flared up due to the high disease pressure caused by the warm temperatures and high humidity during the last month.

All greens, tees and surrounds will receive applications of liquid fertilizer and iron in the coming weeks. These scheduled monthly applications are to help to maintain acceptable nutrient levels, colour and aid with disease suppression throughout the winter months.

A second application of pre-emergent product will be applied to fairways to give us further Poa annua control over the next 12-14 weeks. Poa annua that is present will also be targeted with a post-emergent product.

April Course News

	April 2013	April 2012	average
Rainfall	42 mm	44.5 mm	54 mm
Year to Date	103.5 mm	192 mm	141.5 mm

Average Temp.	23.5°C	22.1°C	-
Average Humidity	64.2%	61.6%	-

Once again April provided us with a very similar weather pattern to the previous two months; a very dry start to the month with above average temperatures giving us the warmest April in the last seven years, and then some much needed rain at the end of the month which significantly boosted the total for the month. The 25mm of rain that fell on the 21^st of April was the biggest single day rainfall that we have received since the 17^th of August last year, a period of approximately eight months.

In lieu of a full autumn renovation, this year greens were mini-tined and fertilised with an application of a biologically enhanced organic fertiliser; this will further improve the health, vigour and condition of the sward prior to the start of winter.

Further landscaping works to continue to improve the area at the 11^th/15^th tee paths have been undertaken, with a large number of positive comments being received from members.

A significant amount of staff time has again been spent on clearing the storm debris generated from the strong winds we received throughout the month.

An application of @8 tonne/Ha of Gypsum was applied to all fairways using our own machinery and labour. The dry weather at the time of application also meant that we were able to dragmat the gypsum into the fairways straight away meaning less impact on play than in previous years.

March Weather Data

	March 2013	March 2012	average
Rainfall	23 mm	79.5 mm	39.9 mm
Year to Date	61.5 mm	147.5 mm	87.3 mm
No. of rain days	5	6	-
Average Temp.	27.2°C	24.7°C	-
Average Humidity	61.5%	62.1%	-

The weather in March followed a very similar pattern to the previous month, with a very dry start to the month and then 19.5mm of rain falling in the last week to give us the monthly total of 23mm. The average temperature for the month was also the warmest in the last six years.

A significant amount of staff time has been spent on clearing the storm debris generated from the strong winds we received throughout the month.

Autumn renovation of tees has been completed with all tees being fertilised, cored to a depth of 75mm, oversown and then sanded to complete the renovation process.

Fairways were fertilised at the begining of the month with their second application for the season of a balanced granular fertiliser and thoroughly watered in using the water we were able to harvest at the end of last month. This has significantly boosted their overall health, vigour and condition leading into the Autumn/Winter period.

Greens were fertilised on Thursday with an application of a biologically enhanced organic fertiliser this Thursday, which will further improve the health, vigour and condition of the sward prior to the start of winter.

Weather Data and Watering Update

	January 2013	January 2012	average
Rainfall	25 mm	25.5 mm	25 mm
Year to Date	25 mm	25.5 mm	-
No. of rain days	3	4	-
Average Temp.	29.3°C	32.2 °C	-
Average Humidity	55.6%	48.2 %	-

The current watering situation had a significant effect on January's work scheduling. Obviously, the main emphasis for January was using the available water as efficiently as possible, this January we only used @ 37% of water through automated programs compared to last year. A far greater than normal amount of hand watering has been carried out to ensure that we get water to the areas we are specifically targeting and also maximum benefit from its application.

The 13.5mm of much needed rainfall we received on the last day of January brought us some welcome relief and brought us up to the monthly average total. This doesn’t tell the whole story as to date the last five months have been particularly dry, and the unusual thing about this year’s weather pattern compared to other dry years is that we have only received three rainfall events in excess of 10mm since September 7^{th –}

·         October 11^th – 24mm

·         January 13^th – 11mm

·         January 31^st – 13.5mm

This has meant that there has not been the usual relief from the need to irrigate because of regular rainfall events. This has the twofold effect of not being able to rest the bores or pump additional water into the 15^th holding dam like we have been able to do in more typical years.

	February 2013	February 2012	average
Rainfall	13.5 mm	42.5 mm	22.3 mm
Year to Date	38.5 mm	68 mm	47.4 mm

February was another month of low rainfall, with the 11mm that fell in the last week of the month boosting the months total to 13.5mm. Although the average temperature for the month has been consistent with previous years, both the second and last week of the month have been cool enough that we were able to harvest water into the holding dam.

The water that was harvested (@3-4 ML) during the first cool spell was drained down and mainly used to water in the wetting agent and pre-emergent Poa annua control applications. All fairways received three full irrigation cycles over a five day period (@2.14 ML) which gave them a much needed boost. The water that was harvested during the second cool spell was drained down at the start of this week and is currently being utilised over the next few days to water in the fairway fertiliser application which was applied yesterday.
