GreenlyWhat to plant in June in Texas
Worked out for 10 cities from their own weather and frost dates, by zone.
What to sow and plant in June in Texas, by zone: frost-free, highs above 82 °F (Dallas, Houston and 8 more): tomato, bell pepper, zucchini, green beans, cucumber and 22 more.
In Texas, June is summer.
Frost-free, highs above 82 °F: Dallas, Houston, Austin, San Antonio and 6 more
In June, on average, these cities have highs of 89 to 98 °F and lows of 66 to 78 °F, 0.9 to 7.6 in of rain on 3 to 18 days; the day lasts 13 h 45 min to 14 h 31 min (on the 15th).
No frost in June in 10 years of data: frost-tender crops can go in too, if it is warm enough for them.

How we work it out
For each city we use its average weather in June and the months after (highs, lows and rain for 2016–2025, ERA5 reanalysis via Open-Meteo) and its average frost dates. A crop starts in June if the month's mean temperature reaches the minimum soil temperature for germination on its card (we use the mean air temperature as a stand-in for the soil's) and if, over its first months (up to three), the average highs stay within its group's range, with no frost for crops that cannot take it. Crops started indoors count from the month they are planted out.
Temperature groups from Colorado State University Extension: cool-season crops prefer 60–80 °F and lose quality in heat; hardy ones grow in days as cool as 40 °F, semi-hardy ones from 40–50 °F (we use 50 °F); warm-season crops need days above 55 °F, and the most tender (tomato, pepper, eggplant, melon, watermelon, squash) above 60 °F, up to 95 °F. Crops the guide does not name go into the stricter group by their frost hardiness. Fava (broad) beans, which the guide does not name, count as hardy: hardy varieties are sown in fall and overwinter (RHS). Garlic and bulbs: a month before the first frost, and later only while the ground is not frozen (as on each city's page).
This is a general rule from averages: your garden can be a week or two earlier or later, and a greenhouse or a cold frame brings the season forward. Greenly works out the dates for your location.
