Rain
The past week was drier or much drier than normal nationwide. Rainfall totals ranged from just 0.4mm in Johnstown Castle, Co. Wexford to 13.1mm in Roches Point, Co. Cork, equating to between 2% and 83% of normal. The weather over the coming week will be mixed with some rain and drizzle or showers at times, but a good lot of dry weather at times too, especially from Thursday afternoon until Saturday evening. While there's uncertainty in the forecast details from early next week, it looks like rainfall totals of just between 2mm and 14mm are forecast for much of Munster and Leinster, equating to be between 12% and 85% of normal, driest along the south coast. Further to the north and west rainfall totals are expected to range from 15mm to around 50mm, highest in the west, equating to between 115% and 240% of normal.
Temperatures
Mean air temperatures over the past week were a little above normal, with values ranging from 15.0 to 17.2 degrees, which is between 0.5 and 1.5 degrees above normal. Soil temperatures are also above normal, ranging from 16.1 to 19.1 degrees, which is 1.0 to 3.2 degrees above average. Air temperatures in the coming week will remain similar, generally around average or 1 degree above. Soil temperatures will also remain above average.
Sunshine
It has been rather dull over the past seven days with below normal sunshine amounts nationwide. It was dullest in the north and parts of the west, with only 9.5 hours of sunshine recorded at Ireland West airport, Co. Mayo and 10.2 hours recorded at Malin Head, equating to 33% of normal in both locations. The highest amount of sunshine was recorded in the south where 29.4 hours were recorded at Cork Airport, equating to 79% of average. The weather will be mixed over the next week, so sunshine amounts are likely to be near or possible a little below normal.
Drying Conditions
Drying conditions will generally be moderate to good at times through the week, but reducing poor at times too, especially on Wednesday and again later in the weekend and early next week.
Spraying
Occasional rain, drizzle, showers and breezy conditions will hinder spraying opportunities at times through the coming week, and with the possibility of more in the way of wet and windy weather on Monday. However, there will be some opportunities for spraying, especially later this current week and to start the weekend.
Field Conditions
Currently, most soils are trafficable, with soil moisture deficits (SMDs) generally ranging between 5mm and 56mm, driest in the south, with some restriction to growth in the far south. However, parts of the north and northeast are wetter, where some soils are saturated or waterlogged. With mixed conditions over the coming week, there won't be too much change to field conditions, though some soils in the north and northwest will become a little wetter.
