This depends strongly on humidity.

No it doesn't.
The efficiency of sweating depends on rel. humidity. Not what's being discussed here.
The fact that increasing airflow will increase the rate at which you heat up (and how much heat your body must shed) if that airflow is hotter than your core body temperature is just physics 101. Why do you think fan-forced ovens have lower cooking times or temperatures in recipes?

The minimum temperature to which you can evaporatively cool something also depends on humidity. If evaporation is still doing anything (i.e. wet-bulb temperature does not exceed body temperature, in this context), increased airflow will absolutely still have a cooling effect.
The more wind you experience (or the faster you ride your bike) in those conditions, the more work your body needs to do for maintaining homeostasis via sweating. You will certainly not perceive a >39c wind as a 'cooling' wind in any conditions, and the faster that wind is the hotter it will feel.
