While concrete can be poured year-round, spring, summer, and early fall are typically the best times to pour concrete due to the more favorable weather conditions (moderate temperatures). Concrete needs to cure at a proper temperature (ideally between 10°C and 20°C), and pouring in very cold weather can cause issues with setting and curing. In winter, we use special techniques, like heated blankets and additives, to help the concrete cure properly, but it generally does require more attention to ensure quality results and adds to the cost of completing the project.
