How does weather at Sydney Airport affect flights?
Wind direction is the critical factor. Sydney Airport operates on a north-south runway alignment, so strong crosswinds from the east or west can reduce capacity.

What weather patterns cause the most disruption?
Southerly busters are the classic Sydney Airport weather warning trigger. These rapid wind changes arrive in summer with little notice, bringing gusty conditions and a sharp temperature drop. For longer-range planning, the sydney airport weather 14 day forecast helps identify broad patterns, but hourly updates are more reliable for same-day decisions.
