You are past peak pilgrim on that route. Given the date, like almost September 1, most summer vacations are over and done with. Students are preparing to return to class.
The peak summer volume for departing a starting point on a month-long Camino, like: Le Puy, St. Jean Pied de Port, etc. is gone. Except for weekend departures the biggest waves of pilgrims are at least a week or more in front of you. Enjoy the solitude.
This is like turning off a hose faucet, with a stretched out garden hose attached. It takes a few moments for all the water to drain from the entire hose. The Camino works the same way.
Long-walk pilgrims starting at Le Puy or SJPdP in around mid August are about half-way to Santiago by now, more or less. By mid-September, the 2017 "season" will mostly be past. To be sure, there will be more pilgrims coming, but the large surges and waves of pilgrims is over for this year.
This signals the start of the autumn "hip season." Many of us veterans prefer to walk our Caminos either at this time of year, through the end of October, or from the end of April through early June. Most albergues are still open, yet the crowds are gone, There is no bed race, the temperatures are more moderate, and rainfall minimal (relatively - this is largely Galicia).
I hope this helps.
