1996 Honda Prelude hard to shift gears

I haven't drove my car in about 3 months. Its cold weather now and aroun 30-40 degrees. I went to drive it and push the clutch down and it felt real spongy and it did not want to go into gear as easy as it should. So I drove it to my destination and it was hard to put it in all the gears but manage to get it in gear without forcing it. I left my destination 3-4 hours later and I shifted into gear easier than earlier that day. Is there a minor transmission fluid problem or major clutch repair problem or is it the cold weather not driving as often problem?
