As temperatures finally drop across Cork following recent warm weather, motorists are being warned about potentially dangerous road conditions when rain returns to the Rebel County.

The combination of heat and drought creates a perfect storm for slippery surfaces once precipitation arrives. During dry spells, oil residue, rubber particles from tyres, and other debris accumulate on road surfaces. When mixed with the first rainfall, these substances create an extremely slick film that can catch drivers off guard.

Road safety experts note that the first 10 to 15 minutes of rainfall after a dry period are particularly hazardous, as the water hasn’t yet washed away the accumulated grime.

This phenomenon affects all road types, from the N40 to smaller local routes throughout Cork city and county.

Essential Safety Tips for Post-Heatwave Driving:

• Reduce your speed significantly below normal wet weather driving speeds. The road surface can be considerably more slippery than during regular rainfall.
• Increase your following distance to at least double the normal gap. Stopping distances can increase dramatically on these greasy surfaces.
• Brake gently and progressively. Sudden braking can cause skidding, particularly on roads that haven’t seen rain for extended periods.
• Be extra cautious on bends and roundabouts. The combination of turning forces and reduced grip creates heightened risk at these locations.
• Watch for shaded areas under trees or bridges where moisture may linger longer, creating inconsistent road conditions.
• Test your brakes gently when safe to do so after encountering the first wet patches. This helps gauge the actual road conditions and ensures your braking system is responding properly.

The Road Safety Authority advises that these conditions can persist for several hours until sufficient rainfall washes the road surface clean. Motorcyclists and cyclists face even greater risks and should exercise extreme caution.

Met Éireann has indicated that scattered showers are expected across Munster in the coming days, making these precautions particularly timely for Cork motorists.

Remember: it’s better to arrive late than not at all. Allow extra time for journeys and adjust your driving to match the conditions, not the speed limit.
