Spring Arrives Today

It’s been an unusually cold winter with temperatures well below freezing on several days. Blissfully, that is changing now with the arrival of spring. We welcome spring when the vernal equinox occurs on March 20, 2026, at 10:46 am EDT.

Do you have a hard time remembering which date is the first day of spring? If so, that’s because the March equinox can take place on either March 19, 20 or 21. During most of the 20th century, spring arrived on March 21 but the event slides earlier and earlier during the 400-year Gregorian calendar cycle. In the 21st century, the March equinox has only occurred twice on March 21- in 2003 and 2007 and the next time it will happen is in 2101!

Seabrookers Committed to Protecting our Environment

This article is first in a series showcasing how Seabrookers are actively working to protect and enrich our natural environment.

As you enter Seabrook Island, you are greeted by a sign proclaiming it an ‘Audubon International Certified Sustainable Community.’ This designation signifies more than just a title; it reflects the community’s commitment to environmental stewardship and quality of life.

In 2017, the Seabrook Island Property Owners Association (SIPOA) became the first private community in South Carolina—and one of only six in the world at the time—to be designated as an Audubon International Certified Sustainable Community. The certification is based on three main pillars: a healthy local environment, economic vitality, and high quality of life. To maintain this status, the community manages 14–15 focus areas, including wildlife conservation, habitat enhancement, water conservation, and energy efficiency. SIPOA successfully maintained this designation with recertifications in 2020 and most recently in May 2024. Recertification occurs every three years.

Audubon Cooperative Sanctuary for Golf

The relationship with Audubon began decades earlier through the island’s golf courses. In 1995 Seabrook Island’s two golf courses were the first in South Carolina to be certified in the Audubon Cooperative Sanctuary Program for Golf.

2026 King Tides in the Charleston Area

King Tide is a commonly used term describing high tides that are higher than normal. They usually occur during a full or new moon or during specific seasons throughout the year. Charleston’s average high tide range is about 5.5 ft., but during a King Tide event, it can reach 7 ft. or higher.

King Tides can cause flooding in low-lying areas, resulting in road closures on Seabrook Island, as well as the Johns Island and Charleston areas. This is particularly true when a king tide coincides with significant rain and/or wind.

The dates of predicted King Tides for 2026:

April 18
May 15-18
June 14-16
July 13-14
August 11-12
September 29-30
October 10-11
October 26-29
November 24-27
