September 2009 Temperatures Sligo

Weather for October

The next month of the season is October and this traditionally brings a great mix of weather.
Temperatures by day are usually around 12 to 14c and night time values with be in low single figure ranges in clear weather. There are often a lot of storms in Ireland in October especially late on for some reason.
October of 2009 promises a bit of the same really to be honest. The month may start off dry in Ireland with some bright spells and light winds but rain will soon sweep in from the North and West. This will be the pattern for the whole month from then on with just brief dry intervals. However although rainfall will be plentiful throughout the month there will not be the high figures that we saw during July and August. Temperatures will be well up to normal too and some mild nights may well mean that Ireland will experience one of its warmer Octobers. Frost often occurs during this mid -Autumn month but this will not be the case in 2009 as the Atlantic will influence the weather for the most part.

September to end on a High?

The Area of High pressure that is bringing the current welcome spell of fine and settled weather (albeit with cool nights) looks like fighting until the end of September at least. It may not be over us but it will be near Ireland and the UK possibly to the Northeast with the Autumn Lows kept out frustrated in the Atlantic wondering whats happened their ease of access over the Summer. Temperatures of 17c are likely a lot of days till the end of the month but the monthly average temperature is down on average due to some uncharacteristically cool nights. In Ballyhaise in Co Cavan the temperature dipped to 2.2c on 13th September!

Weather for Remainder of September

The weather forecast for the rest of September is looking fairly dry overall when compared to normal especially over the South and the East. In recent days temps have been around the 20c mark hitting 22c at times in the South west of Ireland as the final dregs of Summer heat are dragged out.

The second half of September is now close by and this means that the nights are getting longer and the possibility of 20c being reached are becoming less and less likely. Still temperatures will probably stay respectable for the period around the 17c mark but nights have been cool since the start of the Autumn and there was even a grass frost on 12th in parts of the midlands.

Toward the end of September and especially in the period after 20th the West and North will see a lot more in the way of rain with rainfall totals in this period here near or above the seasonal average. The South and East will fare a lot better with rain below average but sunshine totals will only be average for the time of year too.

Dry weather here to stay.

Its here at last and it deserves to be in BOLD. The dry weather that has been championed for virtually the whole seond half of the Summer has finally arrived as planned in September. Now the nights will be chilly in the countryside of Ireland and the UK but the towns and cities will be 8 or 9c as opposed to the 4 or 5c that will be experienced in the country. This weather is going to last too (because its not Summer anymore) as long as 20th September but the most likely period is 15th or 16th

Heres the scenarios:

September 15th or 16th - Weather breaks in North and West 20%

September 17th - 18th - Breaks Countrywide 60%

September 19th - 20th - Breakdown occurs with wind and rain 15%

September 21st onwards - Unsettled weather till the end of the month

UPDATES WILL OCCUR....................

Signs of improvement

All signs are there for an improvement in the weather from next wednesday 9th September. original forecasts pointed to a better picture from 5th September but a "fly in the ointment" Low Pressure intervened and is going to bring some more rain and winds for the next couple of days, although there will be some dry spells as well. Temperatures will be a rather cool 15 or 16c. After this things should pick up with the sun breaking through and rainfall becoming less plentiful and temperatures reaching the Low Twenties. How long this lasts is open to debate but long range forecasts are showing High Pressure to the South and West of Ireland for the Rest of September (and not 500 miles to the South like in July and August).

Summer ends in ... Floods!

After one of the wettest Summers on record, August sure went out with a bang. A whopping 36.7mm of rain fell in Sligo flooding many of the towns roads ("road flooded" signs were everywhere) while at the station in Johnstone Castle in Kilkenny there was 34.6mm. The figure of 36.7mm in Sligo was the wettest day recorded at the weathergossip weather station since its inception at the start of May. It also has made August a lot wetter overall than it had been in the provisional graphs for Summer that are printed on this blog.
