As a gardening and landscaping expert, I can confidently say that broccoli does not germinate well in hot weather. In fact, it prefers cooler temperatures for successful germination and growth. Let me explain why.
Broccoli is a cold weather crop, meaning it thrives in temperatures between 65 and 75 degrees Fahrenheit (18-24 degrees Celsius). These moderate temperatures provide the ideal conditions for broccoli seeds to germinate and for the plants to grow healthy and produce a bountiful harvest.
When the weather gets too hot, typically above 75 degrees Fahrenheit (24 degrees Celsius), broccoli plants tend to bolt. Bolting refers to the premature flowering of the plant, which negatively affects the quality and taste of the broccoli heads. Instead of forming the tight, compact heads that we desire, the plant diverts its energy into producing flowers and seeds.
Hot weather can also lead to other issues for broccoli plants. The heat can cause the soil to dry out quickly, making it difficult for the seeds to germinate and for the young seedlings to establish themselves. Additionally, high temperatures can stress the plants, making them more susceptible to diseases and pests.
Based on my personal experiences and observations, I have seen broccoli struggle to germinate and grow in hot weather conditions. In particularly hot summers, I have noticed poor germination rates and stunted growth of broccoli plants. The few plants that did manage to grow in such conditions often bolted quickly and did not produce satisfactory heads.
To give your broccoli the best chance of success, it is recommended to start seeds indoors or in a cool greenhouse during the hotter months. Once the temperatures cool down and are within the optimal range, you can transplant the seedlings into your garden or outdoor containers. This way, you can extend the growing season and avoid exposing the plants to excessive heat during their critical early stages.

Hot weather can cause the plants to bolt, leading to poor quality heads, as well as other challenges such as drying out the soil and increased susceptibility to diseases and pests. Starting seeds indoors or in a cool environment during hot weather can help ensure better results.
