Next Full Moon is the Cold Moon of December 2099 after 8 days on 27 December 2099 at 12:58.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 1236 of Meeus index or 2189 from Brown series.
Length of current 1236 lunation is 29 days, 13 hours and 47 minutes. It is 2 hours and 12 minutes shorter than next lunation 1237 length.
Length of current synodic month is 1 hour and 3 minutes longer than the mean length of synodic month, but it is still 6 hours shorter, compared to 21st century longest.
This New Moon true anomaly is ∠49.8°. At beginning of next synodic month true anomaly will be ∠81.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
10 days after point of perigee on 8 December 2099 at 17:50 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 20 December 2099 at 13:16 in ♈ Aries.

Moon is in ascending node in ♓ Pisces at 01:02 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 13 days to meet descending node on 1 January 2100 at 21:13 in ♍ Virgo.
At 01:02 on this date the Moon is completing its previous draconic month and is entering the new one.
6 days after previous South standstill on 12 December 2099 at 13:59 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.351°. Next 7 days the lunar orbit moves northward to face North declination of ∠28.345° in the next northern standstill on 26 December 2099 at 23:34 in ♊ Gemini.
After 8 days on 27 December 2099 at 12:58 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
