In Javelin/long jump/shot put, does it matter if the wind pushes it further?

Question

isnt it unfair. if it was recorded with extremely strong winds?

Answer 1

No, it is just luck.  

Answer 2

Shot is unlikely to have any benefit from wind (it's hardly aerodynamic).

Javelin will have some effect, but it's more likely to be a crosswind that affects it's trajectory.

Long jump will gain some benefit (just like the 100m sprinters) from a tail wind.

The Bird's Nest stadium seems to have been designed to reduce the effects of wind. With open stadia they compensate for wind when reporting the sprint race times.
