South Africa: NSRI releases a "Super Blue Moon Spring Tide" alert!

South Africa's National Sea Rescue Institute (NSRI), a voluntary non-profit organization tasked with saving lives through drowning prevention in South Africa, is appealing to the public to be cautious around the coastline during this Super Blue Moon Spring Tide that has already begun and will peak during the full Moon period from 30 to 31 August 2023. The spring tide will then gradually begin to decline over the next few days into the new week.
Spring tides, which occur at full moon and at new moon every month, can have an increased affect on the strength of rip currents and caution is advised. However, the current spring tide coincides with winter rough sea conditions that are prevailing around South Africa's coastline with cold fronts that have past in recent days and weeks and with storms prevailing deep sea off the coastline, so that the NSRI is appealing to to bathers, coastal hikers, shoreline anglers, boaters, sailors, paddlers and the maritime community to be extra cautious.

The current spring tide is called a Super Blue Moon Spring Tide, because the upcoming full Moon will be the second full Moon of the month, making it a so-called "Blue Moon". This "Blue Moon" will also be a "Super Moon", because the Moon’s orbit is closest (perigee) to Earth at the same time the Moon is full. It will also be the closest full moon of the year, just 357,344 kilometers or so away.
According to NASA, Saturn will be visible as a bright point five degrees to the upper right of the Moon at sunset in the east-southeastern sky. The ringed planet will appear to circle clockwise around the moon as the night wears on.
