Wind Data
Charts built from Rottnest Island and Garden Island station observations — speed & gusts, direction shifts, daily trends and the prevailing sea-breeze pattern. Served from the live DynamoDB; every coordinate is computed at request time and emitted as static SVG.
Rottnest Island
BOM 94602 · 372 observations · 36 today2. Wind direction — today
Each arrow marks direction at one observation; length and colour scale with speed (grey ≤5 kt, blue 6–11, amber 12–17, red ≥18).
3. Wind speed — full data window
Every observation in the snapshot (372 points), day boundaries marked.
Gust (kt)Wind (kt)
4. Daily max wind
Max sustained wind observed per day.
5. Daily max gust
Peak gusts often diverge from sustained wind.
6. Wind direction frequency
Observations per 22.5° bin over the full window — the long wedge marks the prevailing direction.
7. Hour-of-day average
Mean wind (kt) per hour of day across the window — the classic sea-breeze ramp, calm overnight and peaking mid-afternoon.
