What is the latest time baptisms can be done and do you have to have an appointment.

I'd recommend calling the temple directly. You can find their number in the LDS tools app.

You can also look up times on the church's website.

This temple is smaller so calling beforehand, especially if you are wanting to take youth, is the best option. They may want to schedule a time for you or your group to come in depending on who else they are expecting

Walk in baptisms from 7 am to 8am. Appointments other times. It closes at 8pm. This temple is closed from now until March 24th.
