Rain
Rainfall amounts over the past seven days have been above average in all but two stations; Mullingar, Co. Westmeath and Casement Aerodrome recorded 12.9 and 12.8mm respectively (70 and 88% of their respective averages). Elsewhere, rainfall amounts ranged between 19.6mm at Dublin Airport to 87mm at Valentia Observatory, Co. Kerry. While there will be some drier intervals over the coming week, it will generally be unsettled so wetter than averages conditions are expected with 1 to 2 times the average amount expected widely but higher for some northwestern areas.
Temperatures
Mean air temperatures over the past week were mostly within 0.5 degree of normal, ranging from 12.4 degrees at Knock/Ireland West Airport, Co. Mayo to 14.5 degrees at Roche's Point, Co. Cork. Mean soil temperatures ranged between 13.7 and 15.8 degrees which equates to between 0.7 and 1.7 degrees above normal for the time of year. Over the coming week, mean air temperatures will likely be normal or within a degree of normal, ranging generally from 12 to 15 degrees. Mean soil temperatures will likely continue above normal.
Sunshine
Sunshine totals were mostly close to average across Ireland during the last seven days. It was dullest in the northwest with 19.1 hours of sunshine recorded at Knock/Ireland West Airport, Co. Mayo (76% of normal). Cork Airport recorded the most with 39.5 hours (125% of normal). The coming week will be mostly unsettled with sunshine amounts likely to be below normal.
Drying Conditions
Drying conditions will be generally poor over the coming seven days with showers and rain expected most days. Some better opportunities may be possible later in the coming week.
Spraying
Spraying opportunities will be limited due to frequent showers or longer spells of rain, combined with breezy conditions at times. Some better opportunities may be possible later in the coming week.
Field Conditions
Soils across the northwestern half of the country are either saturated or waterlogged, especially for poorly drained soils. Elsewhere, Soil Moisture Deficits (SMDs) are generally ranging between 5 and 35mm, highest in the south and southeast. Over the coming week, the expected rainfall will likely lead to most soils being saturated or waterlogged though some soils in the south and east may fare better with SMDs falling to between 5 and 25mm. There are some indications of a slight recovery in the soils towards the end of the coming week.
