A warm September overall
|
September is finally here and after the dampness and heavy showers of the Summer it is hoped that it will bring a lot more in the way of dry weather to Ireland. Indeed September tends to bring a lot of dry weather in recent years as the kids go back to school and people give up on the idea of a Summer it often happens that we then get a spell of nice warm and dry weather to show how unpredictable the weather can be.
This September is no different as the High that eluded our shores during the Summer finally makes an appearance. The first half of the month in particular looks dry and mild or even warm with the temperatures in the range of 18 to 22c. These temperatures are more akin to values that Ireland should get on a good July.
The second half of September will see more seasonal values as some cooler air pools back in over Ireland and the weather will see more in the way of rain with the temperatures of around 13 to 17c and by then too night time values will probably be a lot lower at 8 or 9c. For the first half of the month the night values will be 13 or 14c at times meaning the average temperature this September could be as high as 14c.
Rainfall for the month is going to be quite low except towards the end of the month there could be some wet and windy episodes and this will bring it near normal but after such a wet Summer September will be the first below normal rainfall month in quite a while.
After the recent warm spell of 8th to 12th August which brought a temperature of 26.5c to Shannon there is going to be a lot of rain or showers for the rest of the month of August. It will also be windy at times too and rainfall figures will be well above normal. Temperatures will be mild though at 16 to 19c.
A mini heatwave for the 9th and 10th of August with temperatures of up to 25 or even 26c. Then at the weekend some very heavy showers could break out as a result of the heat so we will be back to square one with the weather again. However the Low Pressure tends to stay out to the West as opposed to over us so while it will be showery it should stay quite warm, at least warmer than we expected a few weeks ago. The last few Augusts have been very cool but 2012 looks like a warmer one.
Arctic Sea Ice this year will finish at a record low level by the looks of things and this could have implications on our weather in the future as the sea temperature warms and cool meltwater interferes with the Gulf Stream.

| Wet and Windy August |
August is going to start very windy in all parts of Ireland with winds of up to 50mph in parts of the West. Temperatures of 17 or 18c can be expected. It looks quite a cool month overall but there will be an odd day or two when the temperature goes over 20c. However 15 to 18c will probably be the normal range in temperature for this month and rainfall will be 150% of normal. Overall mean temperature will be down 1c on mean.
At last some warmer and drier weather all the way until the end of July so it should remain pleasant in the East and South especially on all of the days with temperatures of 20 to 22c.
In the West and North a different picture the rainfall from time to time and temperatures of 16 to 18c though it will break 20c on occasions in any sunshine. Later in the month it should be dry in all parts of Ireland.

July will be very wet at times just like June in Ireland but will possibly be that bit warmer with temperatures of 19 to 21c on a lot of occasions. Rainfall will again be heavy and though there will be warm spells, firstly at the start of the month, though the cool and unsettled theme will always continue.
Expect a monthly average of 14.1c
Expect Rainfall of 130%
Expect Sunshine around normal
