Dangerous Conditions at Lake Michigan Today (Sat.)

Bill's Blog

Do NOT swim near or jump off the piers and breakwaters today (Sat.) A fairly strong north-northwest wind will develop. That will push surface water into the north side of the breakwaters and create a shore-to-lake current that will can push swimmers out into deeper water. Piers (breakwaters) that can be especially dangerous with a strong north or northwest wind are the pier at Holland St. Park and the North Pier at South Haven.

Waves could increase to 4-7 feet with winds up to 15-25 knots. Small Craft Advisories will be in effect into the evening.

The brisk north wind is probably going to cause Lake Michigan nearshore water temperatures to drop some (upwelling). Water temps. early Sat. AM: South Haven 76.7°, Port Sheldon 74.2°, Ludington 72.6°, Mid-Lake Michigan buoy 74.8°.
