Snaglpus,
It does need heat and longer season.
Martin,
We are having our warmest weather of the summer, currently, but still I am surprised that they are ripening so well. The point was that SOME varieties which are usually longer season or late ripening are ripening early this year, so some reason, and some are ripening well despite the cooler weather. Some are actually later. This was confirmed both by the experience at UC Davis this summer, and with na commerical grower in the central valley.
Further, the characteristics of ripeness have really changed this season. Many varieties are fully ripe before they look as droopy or wrinkled compared with a normal year. I(would have expected the opposite. The BM pictured above, with few, if any cracks, no wrinkles, and still fairly firm, would never have been as ripe inside in previous years.
It should also be pointed out that BM, while ripening fruit, as shown, id also still adding new growth and setting new figs (which have no hope of ripening).
