This is a 7-day snapshot for the Wichita area. The app tracks 16 days for every job site you save — and re-scores it live as the forecast moves.
This page scores the Wichita city center at an assumed 70°F concrete temperature. But your slab is at your address — a different microclimate — and your ready-mix leaves the plant at a temperature that moves the evaporation rate on its own. Three variables this page can't know decide whether your pour cracks: your exact location, your concrete temperature, and what the weather is doing at the hour the truck arrives.
And today is a WARNING day. On a marginal day the pour window is narrow and conditions can turn by mid-morning — right now it looks like 5 AM – 7 PM, but a shift in wind or humidity moves that line fast. This is exactly the day you want the app watching your site instead of a page you have to remember to refresh.
The app closes all three gaps: it reads your GPS, uses your concrete temperature, and scores live — the same ACI 305R science on this page, but for the pour you're actually about to make.
You had to remember to open this page. Tomorrow at 5am, standing on the slab with the truck on its way — will you? PourDay sends the Wichita verdict to your phone every morning, and pings you the moment conditions cross the line. That's the difference between a forecast you check and a call that reaches you. Free on iOS and Android.
Every verdict here comes from the same science as the ACI 305R evaporation rate calculator: the day's air temperature, humidity, wind, and rain combine into a surface evaporation rate, cross-checked against freezing and high-wind limits. When evaporation outpaces bleed water, the fresh surface dries and plastic shrinkage cracks form — which is why the best pour window in Wichita is usually earlier in the day. Know how much you need with the concrete calculator, price it with the cost calculator, then time it here.
Summer heat and dry wind push Wichita toward CAUTION and WARNING by midday; winter brings the opposite risk. Read pouring in hot weather and pouring in cold weather for the mitigation that keeps a pour on schedule, and the curing-time calculator for how long before you can load it.
