Traveller notes on Austin in July

Other months in Austin

Regulars call this the most unpredictable month of the year here, capable of sub-freezing cold or 60-plus Fahrenheit warmth within the same week - one recent February never dropped below freezing at all and ran genuinely hot, while a different year brought a full week of snow and ice. Our row backs the moderate average sitting between those real extremes, 19.6C over 7.4C nights feeling 5C, with 52.2mm of rain across 4.9 days and a trace of possible snow, 0.9cm. Regulars are direct that the practical response is flexibility rather than optimism - avoid non-refundable bookings and be ready to adjust plans on short notice given how fast conditions can flip. The record: humidity 70 percent, 6.8 hours of sun, a 20.5 kph wind and AQI 36.

October is the month regulars rate highest for weather here - late October into November is the best of the year - and the month the city is hardest to book. The festival weekends, the grand prix and the university's home games between them fill the hotels, push rates up and bring minimum stays, so the advice is to book early or choose the weeks between. If you are not going to the festival it barely touches downtown, because the music is all out at the park. Our row gives 29.4C over 16.5C at 62 percent humidity with 91.4mm of rain across 5.7 days - sixteen millimetres at a time. The record: 9.1 hours of sun, a 17.2 kph wind and AQI 38.

April is the month regulars hand out here, and the reason is the hill country: the bluebonnets run from March and the real show is usually early to mid April, with nothing left by summer. The weather half is a slope - pleasant and not yet hot at the start, hot and humid by the end, with nights still in the low teens. Our row averages 27.3C over 15.1C, a twelve-degree gap, at 68 percent humidity with a 21.4 kph wind. Rain is 108mm across 6.5 days, which means storms rather than showers when they arrive. Wildflower roads west of the city are the day out this month is for. The record: a dew point of 13.5C, 8.8 hours of sun and AQI 40.

November is the month Austin regulars hand over as the city's best weather, with the summer humidity gone and highs in the 60s and 70s Fahrenheit through the first half. The month does not hold still, though: by late November it has turned, shorts are unlikely, and the standing description of the swing is 40 one day and 75 the next. What they suggest packing for the last week is jeans, a long-sleeved shirt and a light jacket. Two practical consequences follow: the rivers are too cool for tubing by now, a heated pool aside, and the Hill Country is the day trip people name instead. Our row's 22.9C average high against 10.8C nights is that gap in one line. The record: 5.1 precipitation days carrying 56.2mm, 7.2 hours of sun and AQI 34.
