The north pole is never pointed directly at the sun ever. Doing so would eradicate the presence of the seasons; it would always be hot in the northern area and always cold in the southern parts.
The north pole never points "at" the Sun. About 66 degrees away is the closest it ever comes, on the summer solstice.
Fall or winter.
summer
When the Earth tilts towards the Sun, during the northern hemisphere tilt towards summer, the northern hemisphere enjoys warm weather, while the southern hemisphere enters their winter period. Therefore, the tilted position (of the earth) depends on where the tilt is observed, and in which season.
In the northern hemisphere's summer solstice, around the 21st of June, the northern hemisphere is tilted towards the sun. In the southern hemisphere's summer solstice, around the 21st of December, the southern hemisphere is tilted towards the sun.

America is Northern hemisphere, Africa is Southern. The Earth is tilted at its axis. When the Northern hemisphere is tilted towards the sun they get summer. The Southern, which is simultaneously tilted away, gets winter. Then they change. South tilts towards, and get summer, North tilts away and get winter.
Assuming the observer is in the North, then the southern hemisphere would be tilted towards the sun during the Winter Solstice in December. However, for observers in the Southern Hemisphere, the Winter Solstice would occur in June, and the northern hemisphere would be tilted towards the sun.
When the Northern hemisphere is tilted towards the sun, the Southern hemisphere is tilted away and vice versa. It is this tilt that leads to the seasons. Since the Northern and Southern hemisphere cannot be tilted towards the sun at the same time, they can never have the same season at the same time.
When the southern hemisphere is tilted towards the sun, it is summer below the equator and winter above. Likewise, when the northern hemisphere is tilted towards the sun, it is summer in the north and winter in the south. Hope that helps. Martyn.
My guess is that, Its winter in US when the earth is tilted south to the sun.
At both the winter and summer solstices, the Earth is tilted towards the sun. What differs is which hemisphere is tilted towards the sun. In the northern hemisphere at its winter solstice, the southern hemisphere is tilted towards the sun, while the northern hemisphere it tilted away from the sun. In the southern hemisphere at its winter solstice, the northern hemisphere is tilted towards the sun, while the southern hemisphere it tilted towards the sun. When it is the winter solstice in one hemisphere, it is the summer solstice is in the other hemisphere. For a winter solstice, that particular hemisphere is tilted away from the sun.
If you're in the southern hemisphere, then it is Summer when the southern part of the earth is tilted towards the sun. If you're in the northern hemisphere, it is Winter at that time.
summer
When the northern hemisphere is tilted toward the sun, the southern hemisphere (where Australia is found) is tilted away. This means the sun's rays hit at a much shallower angle. That is what causes winter.
Winter - in the Southern Hemisphere.
Winter - in the Southern hemisphere.
