This month the declination of Mars gets so high that it is beyond the limit set by the Sun, so we say that Mars is "out of bounds." During this time, Mars will have more freedom than usual to accomplish Marsy types of endeavors. On the high end, this could be a great time for groundbreaking work, pushing forward an innovative agenda at work or in your creative endeavors.
At the low end, when a planet is out of bounds in a natal chart, it can relate to the person being seemingly unable or unwilling to question their own desires. Mars is the planet of "I want." So when transiting Mars is out of bounds, it might be that we are less likely to question what we want, and to take actions we might regret later, when Mars comes back into "normal" range.
