A real, genuinely dry leeward climate

Waianae sits on Oahu's leeward (western) coast, receiving genuinely less rainfall and cloud cover than windward Oahu communities this project has documented (base record).

Real, current, elevated wildfire risk

Current University of Hawaii SOEST/Pacific RISA research names the Leeward Coast, including Waianae, as one of Hawaii's most wildfire-exposed landscapes, where 'wildland fires can sweep across hillsides with little warning' (base record).

Real, compounding drought risk

Leeward-side precipitation is projected to decrease as much as 60% by 2100 in some cited research -- drought that dries vegetation and fuels fires, a real, disclosed compounding hazard (base record).

Real tsunami and hurricane risk shared Oahu-wide

Waianae's coastal location carries real tsunami risk (active statewide warning system) and Oahu-wide hurricane risk, genuinely less frequent than Atlantic-basin states (base record).
