Rainfall over the past seven days (08/10/2025 to 14/10/2025) was well below normal across most stations. The highest total was 1.9mm at Malin Head (6% of normal). Other stations recorded very little or no rainfall, for example, Belmullet 0.2mm (1%), Roches Point 0.2mm (1%), and Shannon Airport 0.0mm (0%). The weather is expected to remain mostly settled this week, before turning more unsettled over the weekend. Rainfall amounts are forecast to remain below average nationwide until Saturday.
Temperatures
Average air temperatures last week ranged between 10.1 degrees Celsius at Knock Airport and 12.1 degrees Celsius at Roches Point, Shannon Airport, and Valentia, which is slightly above normal for mid-October. Soil temperatures at 10cm depth ranged from 11.5 degrees Celsius at Knock to 13.6 degrees Celsius at Shannon Airport, also above seasonal norms. During the coming week, daytime temperatures are expected to be around 11 to 15 degrees Celsius, typical for this time of year, with night-time lows between 7 and 12 degrees Celsius.
Sunshine
Sunshine remained well below normal last week. The dullest stations were Shannon Airport and Valentia with 0.0 hours (0% of normal) and Johnstown Castle 0.2 hours (1%), while Claremorris recorded the highest at 1.1 hours (4%). Cloud cover is expected to persist this week, keeping sunshine amounts below normal.
Drying Conditions
Mostly dry weather is forecast for Thursday and Friday, but limited sunshine and generally light to moderate winds may slow field drying. Soil moisture removal will be gradual rather than rapid.
Spraying
There should be good opportunities for spraying on Thursday and Friday while conditions remain mostly dry. Over the weekend, rainfall and stronger winds will reduce spray windows, especially in the west and southwest.
Field Conditions
Poorly drained soils remain saturated. For other soils, soil moisture deficits (SMDs) range from 5mm to 10mm. With dry conditions expected Thursday and Friday, many soils will begin to dry. Over the weekend, however, wetter weather will increase saturation, and moderately or poorly drained soils may become waterlogged.
