Rain
Rainfall totals over the past week were significantly above average nationwide, particularly in the west, midlands, and northwest. The highest recorded rainfall was at Ballyhaise with 90.1 mm (414% of normal) and Claremorris with 98.5 mm (357%). Even traditionally drier stations like Casement (18.9 mm, 112%) and Oak Park (28.3 mm, 147%) reported above-average rainfall. However, the coming week will see a marked shift, with high pressure set to dominate, leading to well below-average rainfall. Dry conditions are expected across most regions, with only isolated drizzle in the northwest and occasional patchy rain in the south and west. The driest conditions are expected in the southeast, supporting improved field access.
Temperatures
Mean air temperatures have been above normal across all stations, with anomalies ranging from +1.0°C to +2.7°C. The highest mean air temperatures were recorded at Shannon Airport and Oak Park (14.0°C), with Casement and Dublin Airport (13.7â"13.9°C) also above seasonal averages. Soil temperatures are similarly elevated, ranging from 12.2°C (Knock) to 14.1°C (Shannon). This represents a +1.6°C to +2.7°C anomaly, supporting continued grass growth. Soil temperatures are expected to remain relatively steady in the week ahead, with no major cooling forecast.
Sunshine
Sunshine totals were mixed, with many stations recording near or below average values. The sunniest location was Casement Aerodrome with 18.1 hours (72% of normal), while Valentia recorded just 7.5 hours (34%). Despite the dry outlook, cloud cover is expected to persist, so sunshine levels will likely remain near or slightly below normal, particularly in the west and northwest. The east and southeast should see the best of any sunny spells.
Drying Conditions
Drying conditions are expected to improve significantly this week due to much reduced rainfall and light winds. Cloud cover may limit drying efficiency at times, but overall, this will be a good week for drying, especially in southern and eastern regions.
Spraying
Spraying opportunities will be much more favourable than in previous weeks. Light winds and drier conditions will support operations, although early morning fog and residual surface moisture may limit windows, particularly in inland areas.
Field Conditions
Recent heavy rainfall has left soils very wet, particularly in poorly drained areas of the west, midlands, and northwest. However, with the forecast dry spell, soil trafficability is expected to improve steadily, and most soils should become workable later in the week. Areas with better drainage will see more rapid improvement.
