Encountered windshear inside the final approach fix to land XXR at ZZZ. Upon windshear warning I advanced full power and followed FD escape guidance; the FO/PM (First Officer/ Pilot Monitoring) advised tower we are going missed due to windshear. Once clear of the windshear we cleaned up the aircraft and asked for delay vectors to remain in the area as the weather may be clearing quicker and we had sufficient fuel to hold. In the moments following; we received a call from the FA (Flight Attendant) and were told that she felt ill and there were many passengers that were feeling sick due to the turbulence. During this call; another aircraft had gone missed due to the same windshear. I made the decision to divert to our filed alternate due to the safety and consideration of the passengers and crew on board. We would not put them through the same approach and more than likely receive the same result. Dispatch; ATC; the flight attendants and passengers were informed of the decision to divert. We sent a message to Dispatch asking to have medics standing by as a precaution for the passengers who had felt ill; this was also forwarded by me to ATC. No emergency was declared. Landed ZZZ1 without incident and medical personnel met the aircraft at the jet bridge; walked down the aisle and ensured each passenger was well. All were in good health and happy to disembark. We were delayed 2.5 hours on the ground out of [our departure field] and rerouted/refiled at 8000 feet. This added time and our original weather window was closing. I had asked for maximum fuel on board in anticipation of weather and ground delays being an issue. All these elements were taken into consideration and added to our plan to be on the lookout for sporadic airspeed deviations and review windshear escape maneuvers; go-around procedures; crosswind limitations; diversion/hold procedures and were all briefed.
