When does it start cooling off for the Autumn season in Austin? (Howe: 2013, camp)

I read somewhere that this summer we've had the most consecutive number of triple digit degree days in history.

A few years back (2011) we had something like 27 days in a row over 100 and 90 something total for the summer. It was brutal. I don't think we broke either of those this year, but have not kept track, really.

I would say end of october the mornings are usually quite cold and the afternoons are reliably comfortable.

I have periodically trained for the enchilada buffet (80 mile mountain bike race in austin). For the two months leading up to the race it is typically brutal in september then starts to get comfortable/cold october mornings. The day of the race (end of oct) it

1) often rains so the race is rained out
2) is freezing in the morning
3) comfortable/slightly warm when riding on 360 in the afternoon.

I wont swim in under 90 degrees, so the end of swim season usually happens sometime in october.

7 years isnt sufficient to spot any trends when it comes to weather. Anything you "think" is just confirmation bias of whatever you believe.

It all depends on how you define hot / warm / mild / cool / cold. Some folks think anything under 60F is "cold". Others think anything over 80F is "hot." I personally don't use those terms as either of those temperature definitions.

It's fair to say that the first significant downward trend in temperature (often also associated with a downward trend in humidity) typically happens anytime from mid-September to mid-October, when low temps in the morning go down into the upper 50s to mid-60s. You really gotta hate those mid-October years (fortunately not very common...yet) because it seems like you just wait FOREVER. Daytime temps may still get to 90, but usually that's mitigated by lower humidity.

Last year was extremely unusual in that there was a strong cold front right after Labor Day. I honestly can't remember anything like that before.

This year's heat wave right at the beginning of autumn is definitely not typical, but I do recall having it happen before.

Fortunately, the first real influx of early-autumn drier northern air should happen early next week.

The forecast this week looks beautiful. This is my personal favorite weather: cool mornings with daytime highs that peak in the lower 90s.

Not soon enough. Fall gets less and less each year and I've been here 18 years.

This week is nice, except for the 90s. We should be through with those temps by now.

This summer was absolutely brutal, right on up there with 2011. I again suffered landscape losses due to the extreme unrelenting heat.

I didn't move down here for the weather.

Eh, the last week of September is 90 F or higher ~30-35% of the time, based on 100+ years or so of data. So while last week was much hotter than historical (<10% of the years have been that hot), this coming week is not that odd.

Since 2004, I recall it being less than 90 degrees during the beginning of October plenty of times. I recall the weather becoming less hot the further along in September as well. Maybe 2011 was when things started to change (I am not counting the one off 100 degrees here and there), but either way it's getting hotter and hotter each year and we're getting fewer temperate months. My husband is a native and he says the same thing.

I think the resuming drought is even more concerning.

I agreed to move here for the weather; but we arrived just in time for FIVE years of record-setting heat and drought!!! We often heard it was one year of drought followed by two years of floods or vice versa; but we saw nothing but drought and heat for the first five years!!!(Except for ONE day in Sept, 2010 when we got 13" of rain!!!).
