The Hand Test, Explained
Hold your palm about 3-4 inches above the grate, over the zone you're about to cook on, and count how many seconds you can comfortably hold it there before pulling away. Match the count to the chart below:
| Seconds | Heat Level | Approx. Temp |
|---|---|---|
| 2-3 sec | High | 450-550°F+ |
| 4-5 sec | Medium-High | 400-450°F |
| 6-7 sec | Medium | 350-400°F |
| 8-10 sec | Medium-Low | 300-350°F |
| 10-12+ sec | Low | 250-300°F |
The hand test is a quick estimate, not a precise reading — a grill thermometer or point-and-shoot infrared thermometer is more accurate, especially for longer cooks like ribs where a few degrees matter over several hours.

How Wind and Cold Weather Change These Numbers
Every temperature and time on this page assumes calm, moderate-weather conditions — wind and cold both push the real numbers around, sometimes significantly. Wind cools the grill body directly and disrupts airflow inside it, which can create uneven hot spots even at a steady dial setting; on a charcoal grill, wind also burns fuel faster, so keep extra charcoal on hand on a gusty day. Cold weather (below about 40°F) typically adds 25-50% to preheat time and can meaningfully extend cook time on longer items — Weber's own guidance suggests adding a couple of minutes per side for direct-heat items in cold weather, and checking indirect cooks more often since a closed lid loses heat faster to cold outside air each time it's opened.
The practical fix in both conditions is the same: cook to internal temperature, not to the clock. The times in the chart above are reasonable starting points in normal weather, but treat them as a checkpoint to start testing doneness, not a stopping point — especially for anything windy, below-freezing, or being cooked indirect for more than 20-30 minutes.
Frequently Asked Questions
How do I check my grill's temperature without a built-in thermometer?
Hold your palm about 3-4 inches above the grate, over the zone you'll be cooking on, and count how many seconds you can hold it there before it's too hot to keep still. 2-3 seconds means high heat (450°F+), 4-5 seconds is medium-high (400-450°F), 6-7 seconds is medium (350-400°F), 8-10 seconds is medium-low (300-350°F), and 10-12+ seconds is low (250-300°F).
How do I know whether to use direct or indirect heat?
Use direct heat (food right over the flame) for anything that cooks in under 20-25 minutes and is relatively thin — burgers, steaks, chops, fish, shrimp, and most vegetables. Use indirect heat (food beside the flame, not over it) for anything larger or longer-cooking — whole chickens, ribs, roasts, and brisket — so the outside doesn't burn before the center finishes.
Does a gas grill run at the same temperature as a charcoal grill?
They can reach similar temperature ranges, but charcoal typically runs hotter at its peak for searing and holds heat more consistently over a long cook, while gas is faster to start and easier to dial to a precise, repeatable temperature. The hand test and target temperatures on this page apply to either type — set up two heat zones (direct and indirect) regardless of which grill you're using. See Charcoal vs Gas Grill: Temperature Differences for the full comparison.
Do I need to adjust these times in cold or windy weather?
Yes — expect 25-50% longer preheat time in cold weather, and add a couple of minutes to direct-heat items since both wind and cold pull heat away from the grate faster than the calm-weather times above account for. Cook to internal temperature rather than the clock whenever the weather isn't mild.
