Met Éireann is issuing and extending a Status Yellow high-temperature warning for parts of Ireland as a heatwave brings daytime highs in the upper 20s, with forecasts reaching around 30C in some areas. The warnings apply to selected counties, with at least 12 counties identified in one report. Alongside the heat advisory, some regions introduce or expand night-time water restrictions during the highest heat periods. Additional measures are also referenced in the coverage, including night-time restrictions to manage demand and wildfire preparedness steps. One report notes that an Orange alert for forest fires remains in place while the heat warning is active, reflecting heightened wildfire risk during dry, hot conditions. Another source indicates the heat warning is extended through to the end of the week. Overall, the reporting converges on the same message from the national meteorological service: temperatures are expected to be above normal, public guidance is in effect for affected areas, and authorities are preparing for heat-related impacts, including water conservation and fire risk.
