It can, but I typically see heatwaves prematurely ripening the fruit.

From my observations, the tiny fruit (think 'pea-sized') kind of go into a stasis when a heatwave hits. Those fruit tend to take a while to get going again.

For fruit that are larger (like 'golf ball size' and bigger) when the heatwave hits, they tend to ripen very early. Case in point, my first and only ripe fruit so far this year was a ten-ounce OTV Brandywine. I picked it yesterday, 58 days from transplant (and 110 days from germination) - that was quite a surprise. In a year with more moderate/normal temperatures, that fruit would likely take a few more weeks to ripen and grow to be notably larger. Mother Nature is a fickle mistress.
