The sun is in the exact same position right now that it will be in at the end of September, so the areas that are getting direct sun now are the areas that will be getting direct sun at the end of the growing season. The sun will gradually move northwards in the sky over the next 3 and a half months, then start moving back south. Take a compass with you when you go out to scout your grow spot. As a general rule of thumb, anything to the north of the areas that are directly lit now will get direct sun all summer long. Stand in those spots and look in every direction, paying particular attention to the east and west. If there are trees or other obstructions too close to the east or west, they'll block the morning or afternoon sun, and the closer they are to the grow site the less direct light the plants will get each day. Trees that are too close to the north will also block the sun as it moves northward in the sky. Anything to the south of you will not block any more sun during the growing season than it is this week.
When you're doing this, it's important to imagine what the trees will look like with leaves on them. If the site seems bright, but is surrounded by bare trees, don't be fooled by how much light it's getting right now. In 3 months, those bare branches will be solid walls of leaves, and your plants will be shaded.
i was wondering since there is still snow on the ground and when it starts to melt in the area's that is open ground would they be the best place to grow? And would the sun be in a different position in the sky during the summer then it is in the winter? thanks and +rep
