Different fall vegetables have varying temperature preferences for optimal growth. Here’s a general guideline for the ideal temperature ranges for growing some common fall vegetables:

• Lettuce: Lettuce prefers cool temperatures between 45°F to 75°F (7°C to 24°C). It can tolerate light frosts but may bolt (go to seed) in warmer temperatures.
• Spinach: Spinach thrives in temperatures between 50°F to 70°F (10°C to 21°C). Like lettuce, it can tolerate light frosts.
• Kale: Kale is quite cold-hardy and grows well in temperatures between 40°F to 70°F (4°C to 21°C).
• Broccoli: Broccoli prefers cooler temperatures between 60°F to 70°F (15°C to 21°C). It can tolerate light frosts and even a bit of snow.
• Cauliflower: Cauliflower grows best in temperatures between 60°F to 70°F (15°C to 21°C), similar to broccoli.
• Cabbage: Cabbage also prefers cooler temperatures between 45°F to 75°F (7°C to 24°C).
• Carrots: Carrots can tolerate a range of temperatures, but they prefer around 60°F to 70°F (15°C to 21°C) for optimal growth.
• Radishes: Radishes grow well in temperatures between 45°F to 75°F (7°C to 24°C). They are fast-growing and can be harvested relatively quickly.
• Peas: Peas are cool-season crops that thrive in temperatures between 55°F to 75°F (13°C to 24°C). They can tolerate light frosts.
• Beets: Beets prefer temperatures between 50°F to 70°F (10°C to 21°C). They can tolerate light frost as well.
• Turnips: Turnips grow well in temperatures between 50°F to 75°F (10°C to 24°C).
• Swiss Chard: Swiss chard prefers cooler temperatures between 50°F to 75°F (10°C to 24°C). It’s relatively cold-tolerant.

Remember that these temperature ranges are general guidelines and can vary slightly depending on the specific variety of each vegetable. Also, microclimates within your garden or local area might influence the actual temperatures your plants experience. Monitoring the weather and providing some protection (such as row covers or cold frames) during extreme temperature fluctuations can help you optimize the growing conditions for your fall vegetables.
