ELLA!!!!! Great to see you!!!!
OooooOOOOOH I live up north. In fact, it's snowy on the ground outside right now and it gets to be negative degrees in the morning.

Your hair will adjust to the new climate... really, it will. I came from a hot California climate and moved into a mountain hiding place, and my hair is actually BETTER OFF than it used to be. The first thing I had to do was shower less (prevent dry skin) and wash my hair less (just washing less would train my scalp to produce less oil. because when it's freezing cold you don't want to have to get up early and shower in the morning!!!! lol) Of course, there's the 2-3 week scalp adjustment period that drives people nuts), and I switched to a gentle shampoo so that my scalp wouldn't overcompensate with oil.. but you already know anyway that it's a positive hair-safe thing to do. I oil once a week before shampooing, as a kind of "OWC" instead of CWC.. but occasionally an OWCC.. Well, this routine is pretty suitable for ANY climate.

Experiment, experiment, experiment. Try a different routine every 2 weeks, one new thing at a time. It took me a couple months to figure out a good oiling routine for this area, but it was worth it. And of course, the shampoo mattered the most when it came to greasies.

Consider the fact that maybe it's the drastic change in your life that's causing a reaction. It might not even be the climate. It sounded strange to me when you said your hair got greasier in the cold new place. ::thinking, thinking:: maaaaybe... your intelligent hair realized it was dry, telegraphed a message to the scalp to produce more oil, and voila!
::thinking, thinking::

Start a hat collection. I don't go outdoors without a hat, bandana, headscarf, or other head covering because the cold on my hair simply makes me paranoid... I've seen less splits and shinier softer hair when using headcoverings often. So not only is a headcovering collection fun, your hair will thank you for it.
