Wind data visualisation examples

Server-rendered SVG charts built from live DynamoDB (468 observations, 2 stations, 2026-05-302026-06-06 AWST). No client-side JavaScript or chart library — every coordinate is computed at request time and emitted as SVG.

1. Wind speed and gusts — today

The simplest visualisation — speed and gust on a shared y-axis. Helpful for an at-a-glance read of how it's been so far today.

No observations yet for this AWST day.

2. Wind direction over today

Each arrow marks the wind direction at one observation. The arrow length and colour scale with wind speed (grey ≤ 5 kt, blue 6–11, amber 12–17, red ≥ 18 kt). Useful for spotting direction shifts during the day.

No observations yet for this AWST day.

3. Wind speed over the full data window

Line chart spanning every observation in the snapshot (96 points). Day boundaries are marked on the x-axis. Useful for trend-watching across multiple days.

4. Daily max wind

Aggregates the snapshot into one bar per day, plotting the max sustained wind observed. Quick way to compare day-to-day intensity.

5. Daily max gust

Same as above but for peak gusts. Often diverges meaningfully from sustained wind in unstable conditions.

6. Wind direction frequency (compass rose)

Counts observations per 22.5° bin over the full snapshot. Long wedges = prevailing direction. The Rocko-area sea-breeze pattern (south-westerlies in summer) shows up clearly here.

Observations counted per 22.5° bin. Wind FROM bearing.

7. Hour-of-day wind average

Averages each hour-of-day across every day in the snapshot. The classic sea-breeze ramp — calm overnight, building from late morning, peaking mid-afternoon — is the shape to expect.
