Does the price of retail space fluctuate seasonally?

I'm going to be opening a retail space in/ near Long Beach Ca.

My business is not likely to have a huge change in sales due to Christmas.

So, if it's not critical to be open by Christmas, can I wait till after Christmas to sign a lease and expect to get a cheaper rate per month? My thought is that more people are trying to start retail businesses before Christmas, placing a demand on space. Then after Christmas there will be more businesses shutting down due to the drop off in sales. So I thought there might be a glut of space available in January driving the average price per foot down.

Is this reasonable, or is the reality different?
