Lukla flight status & weather

1,497 calendar days covered from 28 August 2022 to 2 October 2026. 1,244 had suitable airplane weather at least once. 10 days had no Lukla report, so their conditions are unknown. Conditions may have changed during the day.

We used 5,474 posts from Lukla Weather Update archive, including 4,970 unique Lukla reports. 393 omit an airport code or say only LK. We identify these as Lukla using the channel name and label the airport as inferred in the day details. We exclude messages that identify another airport. We remove duplicate reports and include each calendar day, even when no one posted a report.

Each Nepal day counts once per month, or once in each time range. One suitable report is enough to count the day in green. We flag days with mixed conditions in the details.

For airplanes, green means at least one VFR or OPS NML report without an airplane closure or visibility below 5 km. Exactly 5 km does not close the weather window. Good visibility alone does not establish VFR. Orange means only low visibility, closures or non-VFR categories. Grey means we need more information.

We decoded the archive automatically. Our team has not reviewed each historical report. Missing values and “NIL” stay unknown. A closure for all operations takes priority: we treat it as below 1,500 m and show both flight types as closed, without assuming an exact distance.

Monthly charts use the original Nepal posting date. For time-of-day charts, we use the tower’s observation time or, if it gives none, the time the message was sent. 1,251 reports use message-sent times. 821 reports before 6:00 am and 6 from 6:00 pm fall outside the displayed ranges.

The archive has gaps between updates. These charts help you compare past conditions; they cannot confirm airport opening hours, flights that operated or future weather.

We use 1,500 m as the helicopter visibility threshold for this comparison. CAAN’s published visual flight rules include helicopter exceptions under certain conditions. Your operator and pilot decide which requirements apply to your flight.
