Met Éireann has issued a nationwide heat advisory effective from 9 July 2026, forecasting daytime temperatures of 27-30 °C and high overnight minima through the weekend. The national forecaster says it is “extremely likely” Ireland will record an official heatwave—five consecutive days above the seasonal threshold—by Sunday. Potential impacts listed include rail buckling risks, aircraft performance constraints, and degraded road surfaces. Transport Infrastructure Ireland has pre-treated several motorway sections with reflective surfacing, and Iarnród Éireann has imposed 80 km/h speed restrictions on exposed stretches of track between Portlaoise and Thurles during peak heat hours. Dublin Airport’s operator daa states that while runway performance margins remain within limits, airlines may implement weight restrictions on fully-booked long-haul flights departing in the early afternoon. For employers, the advisory coincides with peak summer travel and the influx of EU delegates. Mobility teams should monitor rail and airline alerts, encourage travellers to carry refillable water bottles (airport security will allow empty bottles through screening), and remind drivers that some regional bus services may curtail air-conditioning to conserve power. Outdoor assignees should observe the Health & Safety Authority’s high-temperature guidance, including modified work-rest cycles. Met Éireann will upgrade to Status Yellow or Orange warnings if thresholds are exceeded; corporate security providers recommend subscribing to push notifications from the Met.ie app. Business-continuity planners should also watch for local hose-pipe bans, which could affect temporary housing and serviced apartments.
