The RAC Boulders are currently wet from heavy rain today (11.3mm) with ongoing showers through the morning, and the forecast shows a prolonged wet spell of 4+ days ahead with over 50mm expected. Rhyolite becomes extremely slippery when wet, making bouldering unsafe — especially at a venue popular with beginners.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
