We were there for a WDW stay and visited Universal on Monday 12/6 and Friday 12/10. The weather was really nice, low 80's, but we stayed off the water rides because it was not hot enough to walk around wet. But others were going on. On Monday it was walk on everything. Friday there were small waits on some rides, due to the fact that it was the first day of the parade. The parade was great. We did go swimming during our stay and it was fine.
