Even without a named La Nina this coming winter, things already look a lot better for you this year, as Indonesia has been having more rain this year than last, and a bit more than average due to the near-La Nina conditions. The current nearly borderline La Nina conditions should persist a bit longer, such as another 2 months, before weakening toward mid-neutral toward winter. But it's the next couple of months that matter for your haze conditions, so I think calling off an official La Nina for later in the year (Nov, Dec, ...) is not as bad for you as it might seem.
