The Earth's orbit about the Sun is closer to the sun than in many, many
years. I want to say 22.
There are 11 and 22 year cycles.
When I lived just off the equator in mid pacific (south pacific
officially) the tides total swing
from High High to Low Low was + 6 to -6. When it was at +6 we had to
watch out for storm
surges - they would stack up on top and overflow the island or cause
real problems.
The -6 was great for shelling - allowed longer time out and in areas not
been in for a while!
