How we estimated this

At the coldest hour (6 a.m.):

18 °F to spare, so warm enough.

Assumptions

Bag categories use typical ratings as sold: summer about 50 °F (10 °C), 3-season about 30 °F (-1 °C), winter about 15 °F (-9 °C). The number in a bag's name is usually its lower limit, so its comfort rating is about 9 °F (5 °C) warmer.
What you lie on: foam mat about R2, thin air pad about R1.5, insulated pad about R3.5, winter pad R5 and up, van bed about R4, air mattress about R0.5. Colder ground needs a higher R-value.
Shelters hold a few degrees early in the night and less towards morning. Wind and clear, calm skies take warmth away.
Weather: Open-Meteo forecast for your spot, on a grid of a few kilometers, corrected to its height.
