Plan your Texas Hill Country celebration with 30 years of historical weather data. Austin's subtropical climate creates two outstanding windows for outdoor events — a spectacular spring centered on March and April, and a golden fall in October and November — flanking a summer that's best avoided outdoors.
Based on 30 years of weather data, Austin has two distinct ideal windows: March–April in spring and October–November in fall. Both offer comfortable temperatures and manageable rain risk:
Historical averages based on 30 years of climate data (1995–2024) from Austin Bergstrom International Airport weather station
| Month | Avg High | Avg Low | Rain Chance | Comfort Score | Event Rating |
|---|---|---|---|---|---|
| January | 63°F | 37°F | 23% | 9/100 | |
| February | 66°F | 41°F | 27% | 62/100 | |
| March | 74°F | 49°F | 28% | 90/100 | |
| April | 80°F | 56°F | 23% | 95/100 | |
| May | 87°F | 65°F | 26% | 72/100 | |
| June | 94°F | 71°F | 21% | 0/100 | |
| July | 96°F | 73°F | 17% | 0/100 | |
| August | 98°F | 73°F | 16% | 0/100 | |
| September | 92°F | 67°F | 20% | 12/100 | |
| October | 83°F | 57°F | 21% | 78/100 | |

These statistics represent 30-year averages (1995–2024) from Austin Bergstrom International Airport. The Comfort Score (0–100) reflects afternoon/evening conditions combining temperature and humidity. Summer scores of 0/100 in June–August reflect extreme heat-humidity combinations (94–98°F highs with 70°F+ dew points) rather than exceptional rain — Austin summers are hot and muggy, not particularly wet.
Austin summers are among the most extreme in the continental US for outdoor events — highs routinely reach 96–98°F with high humidity. Comfort scores of 0/100 from June through August reflect genuine heat stress conditions. Outdoor ceremonies during these months are not recommended without exceptional cooling infrastructure. Even September, at 92°F, scores only 12/100. Plan around this window entirely if possible.
March (90/100) and April (95/100) are Austin's finest months. Bluebonnets carpet the Hill Country roadways, temperatures are ideal, and the city is energetic before summer arrives. April in particular is near-perfect — 80°F highs, 56°F lows, and 23% rain chance. The main caveat: spring thunderstorms can be severe when they do occur; always have an indoor backup plan.
October (78/100, 83°F high) and November (76/100, 72°F high) offer a solid fall window after the brutal summer breaks. Temperatures are very pleasant and humidity drops significantly. November has a longer usable season than most people realize — 72°F highs with 76/100 comfort scores are excellent for outdoor evening events.
Austin's most dangerous weather for events isn't summer heat — it's spring thunderstorms. March and April carry 23–28% monthly rain probability, but when storms arrive in Texas, they can be intense. Any outdoor event in Austin should have a covered backup venue booked regardless of season. The risk is manageable with proper planning.
The Texas Hill Country west of Austin (Dripping Springs, Wimberley, Fredericksburg) offers stunning ranch and vineyard event venues with dramatic limestone bluffs and wildflower fields. These areas run 2–5°F cooler than downtown Austin and benefit from the same seasonal patterns. Our data is for the Austin airport — confirm with your specific venue location.
