Next Full Moon is the Snow Moon of February 2016 after 22 days on 22 February 2016 at 18:20.
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 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 198 of Meeus index or 1151 from Brown series.
Length of current 198 lunation is 29 days, 13 hours and 8 minutes. It is 1 hour and 52 minutes longer than next lunation 199 length.
Length of current synodic month is 24 minutes longer than the mean length of synodic month, but it is still 6 hours and 39 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠292.2°. At the beginning of next synodic month true anomaly will be ∠319.8°. 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°).
1 day after point of apogee on 30 January 2016 at 09:10 in ♎ Libra. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 11 February 2016 at 02:42 in ♓ Pisces.

3 days after its ascending node on 27 January 2016 at 23:58 in ♍ Virgo, the Moon is following the northern part of its orbit for the next 10 days, until it will cross the ecliptic from North to South in descending node on 10 February 2016 at 20:46 in ♓ Pisces.

9 days after previous North standstill on 21 January 2016 at 16:41 in ♊ Gemini, when Moon has reached northern declination of ∠18.375°. Next 4 days the lunar orbit moves southward to face South declination of ∠-18.303° in the next southern standstill on 5 February 2016 at 04:34 in ♑ Capricorn.
After 8 days on 8 February 2016 at 14:39 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
