There was some relief from the harsh wet Spring during last week and the start of this week. The bulk of the country had less rainfall than normal; only the northwest had amounts greater than average. And that trend in lower rainfall is going to continue until the end of the month. Rainfall amounts will generally be in the range 8 to 12mm for the next 7 days or so, which is about 40 to 60% of normal.
Temperatures finally showed some upward movement during last week. There was a general warming with values of 20C being achieved during last Friday and Saturday. The overall result was a 1.5 to 2 degrees increase in mean values for the last 7 days. Also soil temperatures increase by about 3 to 4 degrees. However that warming trend has now been reversed and the outlook for the days going forward is relatively poor. Temperatures will be less than 12 degrees until the end of the month and grass frost will occur on many nights as temps drop to low single figures.
Warmer and drier weather last week led to increased sunshine for most parts of the country, with eastern counties faring best of all. Sunshine hours for last 7 days were highest in Leinster with up to 65 hours being recorded in some parts; this is almost 180% of normal for this time in April.
Drying will continue to be better than average going forward. This will be primarily due to lesser rainfall and blustery winds.
The most favourable conditions for spraying will be over the weekend and during the early days of next week. There will be longer drier periods and the winds will also be less.
