Hi All,

Briefly back from my campervan stint in St David’s, Wales, lovely weather for bodyboarding and eating freshly caught Mackerel from the sea to pan in less than an hour takes some beating :)..(and it’s free)

General Weather Situation

Low pressure is in charge this week and accompanied by the lack of a significant west-east jet stream to move it along, means that it’ll effectively do circulatory laps of the UK and Ireland bringing sunshine and rain to most parts over this week with cool (ish) temperatures.

Regional Specifics & Outlook

The themes of this week is a succession of rain fronts coming into Ireland and moving eastwards into the UK on the back of southerly winds for the UK.
With the position of the low pressure system and lack of Jet Stream, this type of rain pattern is more likely to bring rain to the South-East and East of England and indeed as I type this, that area is currently on the receiving end of some heavy rain, with Mid-Kent reporting 43mm over the last 24 hours and Surbiton 29mm. What’s amazing about that, is that for Kent, that’s more rain than they’ve had for March, April and May combined !.
The rain that’s over Ireland and the South of England will move away this afternoon, but almost immediately will be replaced with a new rain front arriving into Ireland and then into the South-West and Wales by Tuesday early morning. This rain will push eastwards through the day. The cycle is repeated all week continuing into the weekend with a dry start early in the U.K and then showers arriving by the afternoon. (So if you are spraying, first thing is ideal)
Temperatures will be cool, mid teens and today will probably be the least windiest day of the week with winds picking up from tomorrow and staying with us all week with the weekend looking very windy and possibly quite wet on Sunday.

Looking further ahead, this low pressure is going nowhere fast, but a subtle change at the end of the weekend will tweak its orientation to push strong South-Westerly winds and rain across Ireland, North Wales, the North and Scotland, with slightly warmer temperatures for those areas compared to this week. At the same time, the top of a high pressure system influences the South and South-East bringing warm to very warm weather there by mid-week, next week.

Agronomic Situation

The arrival of moisture on the back of the high temperatures of Thursday, Friday and Saturday will kick off latent Fusarium and here as always it’s important to maintain good growth and plant health in order to grow out any outbreaks. If you’ve been PGR’ing and your growth rate is low, it’s important to keep an eye on the progress of the disease because you’re unlikely to be able to grow it out naturally. If you did receive rain and the greens have responded growth-wise, now is the time to lightly verticut and groom to present an even putting surface.

Alot of greens are pale at present and this is a result of Poa just coming out of the seedhead flush, combined with the hot, drying winds of Thursday, Friday and Saturday and now the cool temperatures of the weekend / this week. It’s important to encourage Poa to begin to re-direct it’s energy reserves to growth, rather than seedhead production, so light liquid feeds and aeration such as Sarrell Rolling, Solid Tining will work well together. Again utilising iron with these liquid fertiliser applications will be ideal to perk up colour is the order of the day.

Those winds stayed with us 24hrs of the day and were responsible for 8mm of E.T loss over Friday and Saturday alone, so theoretically you’d have to be applying or receiving 5mm of rain over those two days just to keep up. (Not that many irrigation systems would be achieving even coverage in those winds)
Wind strength seems to be a feature of this year and it does make life difficult, both from an irrigation perspective and from the amount of water lost through evapotranspiration.

All the best.
