Narrative:

My inbound crew was delayed due to weather; customs; and ca request [for] a meal break. Fas arrived at approx xa:30 and FD arrived at xa:45. Paperwork indicates flight was closed at xa:35. Standby fas told us they were called and when they advised the agents the plane was too hot; they were told they must board and passengers said they boarded on time. There was minimum power (lights only) no AC and no air circulating. Passengers were fanning themselves; perspiring profusely and said they had been waiting for about 45 minutes. The ca said it was 27 celsius onboard which may meet the standards to board; but not to sit on a full (including X children) plane for an extended time. When I asked the agent if he had checked the onboard temperature; he said he had no way to do that. 2 managers (did not introduce themselves) later came onboard and said the plane was hooked up to the APU; and I suggested they talk with the passengers about their experience. I later saw the agents on the bridge with what appeared to be a temperature gauge. My concerns are (1) our passengers were needlessly made to sit on a hot plane. (2) pre-boarders expressed their concerns and they were ignored; and (3) the plane was full so there was no social distancing.
