This section is based on the survey article by Martinez et al, "The modern near-surface martian climate: A review of in-situ meteorological data from Viking to Curiosity."<ref>Martínez, G. M., C. N. Newman, A. De Vicente-Retortillo, E. Fischer, N. O. Renno, M. I. Richardson, A. G. Fairén et al. "The modern near-surface martian climate: A review of in-situ meteorological data from Viking to Curiosity." Space Science Reviews 212, no. 1-2 (2017): 295-338.</ref>
Curiosity has measured relative humidity readings of up to 70% in winter, measured at a height of 1.6 meters above ground level (see Sect 14<ref>[https://link.springer.com/article/10.1007/s11214-017-0360-x#Sec14 Sec 14]</ref>. This is in winter with a temperature range of around 50 C and mean temperature around -63 C, so lowest temperature around -88 C (see their figure 5<ref>[https://link.springer.com/article/10.1007/s11214-017-0360-x#Fig5 Fig5]</ref>), and the highest humidity is normally reached between 04:00 and 06:00 Local Mean Solar Time (LMST).. The lowest humidity readings are between 10:00 and 18:000 LMST, when they are typically less than 5%
Curiosity hasn't directly observed the frosts that Viking observed at somewhat higher latitudes. But there is indirect evidence that frosts may form at times.
