Fourteen-day outlook
Projected readiness for each day. Botanical and wildlife bars use forecast temperature. Meteor shower bars combine stream activity, lunar phase, and forecast cloud cover. Aurora bars use the NOAA 3-day Kp forecast when available and a quiet-oval baseline with forecast cloud cover for days 4–14.

Field notes & historical context
Sheltered coves along the New South Wales south coast where Noctiluca scintillans blooms glow electric blue during warm austral months.
Bioluminescent dinoflagellates such as Pyrodinium bahamense and Noctiluca scintillans concentrate in shallow, nutrient-rich embayments during warm months, flashing blue-green when mechanically agitated under moonless skies.

Safety & responsible visiting
Never wear DEET insect repellent, sunscreen, or skin lotions into bioluminescent waters—chemical residues kill dinoflagellate colonies. Use licensed kayak operators and avoid swimming where prohibited.
Natural phenomena depend on live weather, local access rules, and habitat conditions. Verify local advisories before travelling.
