If Earth were not tilted on its axis, we would expect to see that temperatures in summer and winter would be very similar. This is because the axial tilt is responsible for the seasonal variations we experience; without it, the amount of sunlight received at various latitudes would remain fairly constant throughout the year. As a result, there would be less variation in temperature from season to season, leading to milder, more consistent temperatures year-round.
