I cannot see what doubt there would be; this type of situation where a delay on departure causes a misconnect has been ruled by court of appeal in the UK as being one where compensation is due - AA and EK were 2 airlines that tried to argue that a misconnect outside the EU was outside the regulation
The flight was delayed on departure ( according to the OP ) and then this caused a misconnect. Headwinds are not extraordinary
