Some of you will know I’m a keen fisherman and sometimes in conversation I get asked what’s the appeal ?, it looks so boring…well to watch a sunset and sunrise like this, after a crap week of driving on the M25, early starts and late finishes, it’s a tonic indeed 🙂
After a hot, dry week with high humidity, we have a change on the way, but I don’t think it’s going to signal the start of autumn in earnest. This time of year our weather is typically affected by the remnants of tropical storms that move up the eastern seaboard of the United States, cross the Atlantic and push down into Europe. Their effect is dependent on the location of the jet stream – If it is sitting low then these lows push down and bring wet and windy weather, if it is high, they tend to only affect the north of the U.K and Ireland. As it looks at the moment, we’re likely to get the wind from these systems, but not alot of rain for the south of the U.K. It’ll also feel cooler, particularly on Tuesday, Wednesday, before temperatures recover.
General Weather Situation
For the start of the week, we have a low pressure system pushing rain into Ireland and the west coast of the U.K. Primarily this rain will affect Munster, Leinster and a line up from Nottingham to Newcastle, otherwise it’ll be dry, overcast, with the risk of showers increasing overnight into Tuesday for southern areas. Tuesday starts dull and noticeably cooler as that wind swings round to the north and pushes rain south early doors. Later in the day, showers will bubble up across Connacht, Munster and Leinster and the west coast of the U.K but these will dissipate overnight for most areas, except western Scotland. As we start Wednesday, that rain in Scotland will push further south on the back of brisk, north-westerly to westerly winds, so it’ll feel a little nippy in the wind. As we go into Thursday, the winds swing round to the west and increase in strength, but it should be dry over most area of the U.K and Ireland and temperatures will recover slightly from mid to high teens. For the end of the week, it’s slightly tricky as currently the severe low pressure looks to affect the north of the country with very strong westerly winds and some rain, whereas the south should be warmer with only a low risk of rain and recovering temperatures.
At this stage, the weekend looks reasonable, particularly the further south you are, with declining winds and nice temperatures. Further north, it’ll be windier and cooler as the low pressure system has more effect here. It’s a similar picture across Ireland with the north of the country most affected by the wind and rain. For the start of next week, the low pressure system moves away and a weak high pressure pushes up to give settled conditions through to mid-week, so fine and dry.
Last weeks high temperatures have dried a lot of areas out quite quickly from the previous weeks rain and hand watering is the order of the day here. Soil temperatures remain around the 16°C mark, so still quite favourable, with growth just ticking on nicely for greens. Last weeks dry week will have given most people a chance to get on top of outfield areas and with a light rainfall week expected for most areas, that process should continue.
Disease is quite prevalent given the temperatures, humidity and heavy dews of the previous week, with Fusarium quite noticeable, though if possible I’d still try and grow it out rather than spraying (If this is a viable option). I’d expect more activity from Dollar Spot and Red Thread on the back of that humidity, but this should decrease later this week as temperatures slide and with the absence of heavy dews.
Plant parasitic nematodes (PPN) are also quite prevalent at present given the dry conditions and high population counts (August normally marks a 2nd hatch of most species of PPN’s), so expect to see some evidence of activity if you’ve had problems in the past.
The lower temperatures of this week, coupled with strong winds will no doubt knock the colour out of some areas, so I’d look to pick them up early next week after we get the strong winds out of the way at the end of the week. Light rate foliars with iron are the order of the day here. If you’re on a PGR program on greens, I would not be including any in these sprays as lower temperatures and shorter days will take the edge off growth naturally. You also have to have one eye on the fact that when you finish applying PGR’s, there’s always a growth flush roughly a month after the last application as the plant comes out of the effect of the growth regulator. That’s why I’d suggest finishing applications now because you don’t want a growth flush at the start of the main Fusarium pressure time (Early Oct).
All the best…
