Growth slows as dry spell continues

Ireland is set for excellent drying conditions over the next week, but rising soil moisture deficits (SMDs) will hinder grass growth.

The dry spell, driven by a lack of soil moisture, is causing grass plants to struggle with water absorption, leading to wilting, slowed growth, and, in some cases, a complete halt in development.

Met Éireann predicts SMDs will increase by 5 to 15 mm across the country over the next seven days.

For well-drained and moderately drained soils, SMDs currently range from 13 mm in the west to 30 mm in the east, with growth restrictions already evident, particularly in eastern regions.

Poorly drained soils are faring slightly better, with SMDs between 8 mm in the west and 28 mm in the east.

However, continued dry conditions will likely impose further limits on growth, especially in the east, affecting both well-drained and other soil types.

Soil temperatures nationwide are running 3 to 4°C above average, measuring between 9 and 11°C.

At Oak Park in Carlow, the mean soil temperature hit 11.2°C—4.4°C higher than the seasonal norm.

Air temperatures are sitting 2 to 4°C above typical levels for this time of year.

Ireland’s weather will remain warm and dry up to next weekend.

A change to less settled conditions with some rainfall is expected mid-month.
