Full moon, cool air, but oxygen is genuinely stressed.

The 24-hour DO range topped out at just 3.4 mg/L — that's a legitimately hard ceiling, and I can't put a good spin on it. Water temp data is offline today, so I'm working with limited info, but a 62°F morning with light rain and a slowly rising barometer at least hints conditions could ease. I'd hold off and keep an eye on how things develop through the day.
