Short answer
For the newest designs, visit in the weeks before Navratri, Diwali and the wedding season. For better prices and more attention from traders, visit in quieter months, roughly late spring to early summer.
Surat's busiest months are the run-up to the autumn festivals and the winter wedding season, when traders launch new catalogues. Choice is widest then, but markets are crowded, transport is stretched and there is less room to negotiate.
The monsoon brings heavy rain, which can slow movement around the city. If your goal is a long-term supplier relationship, a calmer month often works better.
