Baltic, great campaign.
Hey- just to clarify, Fahrenheit is used for sea surface temperature because that is what the national data buoy center uses.
Every squadron has a slightly different SOP, but when operating in warning areas over the ocean or any international waters with buoy data, we have to check sea surface temperatures.

Basically, when windchill is below a certain temp and water temps are below 50s in Fahrenheit, we are required to wear exposure suits. That way we have a chance of surviving post ejection based on SAR asset recovery times.
FYI- I am a former Tomcat RIO, still flying as a reservist. Currently attached to NAWDC.
FYI x2 - we all HATE these suits.
