Estimated head/tailwind and crosswind for each runway end from the current reported wind.

Use this section to quickly compare current wind alignment across available runways at KBFI. This is intended as a planning aid only and should not replace official performance calculations or pilot judgment.

Current wind is calm: calm wind is not a factor for runway selection, and with no wind there is no head/tail or crosswind component to compute. Live numbers return automatically once a report includes a wind direction.
