A buoy reading is not a go/no-go
LTRM4 measures the water. It does not know your boat. Fifteen knots and three feet is a pleasant afternoon on one hull and a beating on another, and the difference is the two or three numbers you already carry in your head. GoNoGo Weather scores this station and the forecast around it against your own limits and gives you one straight answer, with the hour it changes.

How to read station LTRM4
This is a fixed station: a platform or a shore mast. It reports wind, pressure and temperature reliably and usually carries no wave sensor, so seas here come from the model rather than from an instrument.
Period matters as much as height. Four feet at ten seconds is a long, easy swell; four feet at four seconds is a short steep chop that stops a boat. Wind against tide steepens everything, and a buoy cannot see that from where it floats. Age matters too: stations go quiet, and a reading that has not updated in three hours is history rather than weather.
This station sits in the NWS marine zone St. Marys River Point Iroquois to E. Potagannissing Bay (LSZ322), which is the forecast we read alongside it.
