When Does Pine Island Lake Freeze? Typical Ice-In Nov 29, Ice-Out Apr 6
Pine Island Lake in Todd County, Minnesota usually freezes over around Nov 29, and usually has ice-out around Apr 6, based on Minnesota DNR ice observations recorded between 2013-2024. That works out to roughly 237 days of open water a year. These are typical dates across many winters, not a forecast — individual years swing by weeks in either direction.

These are dates, not an ice-safety reading
A typical freeze-up date tells you when Pine Island Lake has usually iced over — it does not tell you the ice is safe, and we hold no thickness measurement for this or any lake. The Minnesota DNR is explicit that no ice is ever completely safe: thickness varies across a single lake, and current, springs, aerators, and insulating snow all weaken it. Ice that held a truck last week may not hold a person today.
Read the ice-thickness guidelines before going out, and check current conditions with the Minnesota DNR ice-safety page and local bait shops, which track conditions lake by lake.
How much the timing varies
Ice-out on Pine Island Lake has landed as early as Mar 15, 2024 and as late as May 11, 2013 — a spread of weeks around the Apr 6 median. Freeze-up has ranged from Nov 11, 2019 to Dec 19, 2015. That year-to-year swing is why a median date is a planning tool, not a schedule. Freeze-up is driven by accumulated cold after the lake turns over in fall; ice-out by late-winter air temperature, sun angle, and how much snow sits on top of the ice reflecting it. Pine Island Lake carries an overall water-quality grade of A — the full breakdown is on the lake report.
