The past week has been drier than average for the east and south with rainfall totals between 40% and 90% of average there. However, it was rainfall was around average or higher to the west and north, with accumulations up to 136% of normal. The east was the driest region with 9.8mm recorded at Casement Aerodrome, Co. Dublin. The west was wetter with 37.4mm recorded at Belmullet, Co. Mayo. A predominantly southwesterly airflow over the coming week will steer Atlantic fronts across the country, with rainfall most frequent in the west and northwest. As a result, it will be wetter than normal across most of the country, with accumulations expected to be between 120% and 265% of average. However, rainfall along eastern and southeastern coasts will be close to average.


Temperatures over the past week have been around average or slightly cooler, with mean air temperatures ranging between 10.7 and 13.7 degrees, which is between 0.6 degrees above average and 1.4 degrees below. Mean soil temperatures have been warmer than average, ranging between 11.7 degrees in the east and 14.4 degrees in the southwest. This is between average and 2 degrees above average. In the coming week, a predominantly southwesterly airflow will bring milder air over the country. As a result, air temperatures will increase to between 12 and 15 degrees, which is approximately 2 or 3 degrees above the normal. Soil temperatures will remain above average.


Most places have been somewhat duller than average over the past week with the exception of the south coast, where sunshine amounts were around average. The north of the country saw the least sunshine, with 13.1 hours of sunshine recorded at Malin Head, Co. Donegal (62% of average). In contrast, 26.8 hours of sunshine was recorded at Johnstown Castle, Co. Wexford (98% of average). In the week ahead, conditions will often be unsettled with any sunny spells quite limited. As a result, sunshine amounts are expected to be below average.

Drying Conditions

Drying conditions will be mostly good on Sunday with largely dry weather. However, drying will become poor early in the coming week with frequent spells of rain spreading from the Atlantic.


There will be opportunities for spraying on Sunday with largely dry weather and light winds. Next week, spraying will be hindered by unsettled conditions.

Field Conditions

Currently, most well drained soils are near saturation, while moderately and poorly drained soils are waterlogged in most areas. However, soils in south Munster are slightly drier with soil moisture deficits (SMDs) between 5mm in poorly drained soils and 14mm in well drained soils. In the coming week, more unsettled conditions generally will lead to the deterioration of all soils. Well drained soils will reach saturation nationwide while most moderately and poorly drained soils will become waterlogged. However, moderately drained soils in parts of the south and east will remain near saturation.
