Assuming it is visible from a location and under same clarity of sky, the summer portion of the Milky Way is thicker and brighter. The winter portion is dimmer and thinner.
If you wish to shoot Winter Milky Way, you may try it at 9pm+.
If you wish to shoot the Summer Milky Way, it may be just below or slightly above the horizon at 9pm+ next month. Better to wait until 3 AM next month when it is high up in the sky.
Else, if can only shoot around 9pm+, try one month later, i.e. June.
You may download the free Stellarium software to find out when and how Milky Way is visible at different date, time and location: www.stellarium.org. Else you can also try phone apps like Cosmos Navigator (android and iOS).
