Right, just took a look. Still looks warm with current soil temp at 80F in the tropics down there.
Looking at the historical graph, the averages soil temp drops quickly in September based on 5 and 10 year data. He could probably wait, but still think he could drop soon. But you guys have more time down there for sure. Soil temp was 59F last year on Halloween.
