Mean air temperatures were above normal nationwide, ranging from 7.4 degrees Celsius at Knock Airport in Co Mayo to 10.3 degrees Celsius at Valentia Observatory in Co Kerry. All reporting stations showed positive anomalies ranging from 1.4 to 3.2 degrees above average.
Mean soil temperatures were above normal also, ranging between 6.7 and 9.2 degrees Celsius.Mean air temperatures will remain milder than average over the week ahead, ranging 7 to 10 degrees which is 2 to 3 degrees above normal for the time of year. Soil temperatures will remain above normal also.

Sunshine

Sunshine amounts varied significantly. Western stations, such as Belmullet in Co Mayo (48% of normal), were dullest, while southeastern and midland stations recorded higher values, including Johnstown Castle in Co Wexford (131%) which was the sunniest.
Sunshine in the coming period will be variable, with alternating cloudy intervals and occasional brighter spells.

Drying Conditions


Drying conditions are expected to remain poor throughout the forecast period. Frequent rain or showers on most days, combined with saturated soils and generally light to moderate winds, will keep evaporation rates low. Any short-lived improvement will occur only during brief brighter intervals and will not be sufficient to meaningfully improve surface conditions.

Spraying


Spraying opportunities will be very limited. Regular rainfall and short dry intervals, along with persistently wet soils, will prevent suitable spraying windows for most locations. Any usable periods will be brief, highly localised, and timing-dependent.

Field Conditions


Soils remain saturated, with waterlogging on poorly drained land. Field access and workability are poor across both grassland and arable sites. With further rainfall expected, no improvement in field conditions is likely in the short term and moderately drained soils may become waterlogged at times too.
