Next Full Moon is the Wolf Moon of January 2018 after 10 days on 31 January 2018 at 13:27.
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 4 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 223 of Meeus index or 1176 from Brown series.
Length of current 223 lunation is 29 days, 18 hours and 48 minutes. This is the year's longest synodic month of 2018. It is 2 hours and 42 minutes longer than next lunation 224 length.
Length of current synodic month is 7 hours and 3 minutes longer than the mean length of synodic month, but it is still 59 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠198.1°. At the beginning of next synodic month true anomaly will be ∠227.1°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
6 days after point of apogee on 15 January 2018 at 02:10 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 30 January 2018 at 09:54 in ♋ Cancer.

5 days after previous South standstill on 15 January 2018 at 16:28 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.048°. Next 7 days the lunar orbit moves northward to face North declination of ∠20.027° in the next northern standstill on 29 January 2018 at 11:32 in ♋ Cancer.
After 10 days on 31 January 2018 at 13:27 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
