Rain
Rainfall amounts over the past week ranged from a high of 43.0 mm at Valentia to a low of 12.2 mm at Oak Park. Western and southwestern areas were generally the wettest, while eastern and southeastern counties experienced the driest conditions. The coming week will remain unsettled, and the latest forecast indicates a strong southwest-to-northeast gradient in rainfall. The highest accumulations, approaching 70 to 80 millimetres, are expected in the far southwest, while the lowest totals of around 20 millimetres are forecast for parts of Ulster. Much of the country is likely to receive weekly amounts in the region of 30 to 40 millimetres, with coastal areas in the south and west seeing 50 to 60 millimetres.
Temperatures
Mean air temperatures last week were close to seasonal norms, ranging between 6.8 and 9.6 degrees Celsius across reporting stations. Soil temperatures were steady and generally between 6.3 and 9.2 degrees Celsius, remaining slightly above normal in many areas. Over the coming week, mean air temperatures are expected to stay close to average or rise to about one degree above average. Weekly mean values will typically fall between 6 and 10 degrees Celsius, depending on location, with soil temperatures remaining broadly unchanged.
Sunshine
Sunshine levels were quite variable across the country during the past week, with a clear south-to-north contrast. The highest totals occurred in the southeast, where Johnstown Castle recorded 29.4 hours. Sunshine amounts are likely to be near average over the next 7 days with mixed and changeable weather conditions forecast.
Drying Conditions
Drying conditions will remain poor throughout the coming week due to the frequent occurrence of rain or showers. Limited sunshine and saturated ground will further restrict drying potential.
Spraying
Spraying opportunities will remain limited, as unsettled weather and breezy periods will reduce the number of suitable windows for field work.
Field Conditions
Soils remain saturated nationwide, with poorly drained soils fully waterlogged. No improvement in trafficability is expected during the coming week, and saturated conditions will persist across all soil types.
