The base feels-like temperature uses an apparent temperature model: AT = T + 0.33e − 0.70ws − 4.00 where T is air temperature (°C), ws is wind speed (m/s), and e is vapor pressure (hPa).
Vapor pressure is estimated from humidity and temperature: e = RH/100 × 6.105 × exp(17.27T / (237.7 + T)).
Sun, surface, activity, and clothing add simple offsets to reflect radiant heat and workload. This yields the final comfort temperature shown at the top.
Dew point is estimated with a Magnus approximation, helping you judge condensation risk. VPD (kPa) is computed as saturation vapor pressure minus actual vapor pressure, useful for transpiration context.
Comfort temperature is a garden-focused estimate of how warm you feel while working outdoors. It starts with a “feels-like” model that blends air temperature, humidity, and wind, then applies practical offsets for sun exposure, nearby surface, activity intensity, and clothing. The output helps you time planting, pruning, and harvesting when comfort and safety are highest.
Humidity changes comfort by slowing evaporation from skin. When humidity is high, the same air temperature feels warmer, and dehydration risk rises. This calculator also reports dew point as a quick “mugginess” marker, plus vapor pressure deficit (VPD) for plant context. In many growing spaces, a mid-range VPD is often easier for plants to regulate transpiration than very low or very high values. Whenever comfort temperature is high, consider controls: shade cloth, row cover removal, fans in tunnels, and shorter watering cycles. When it is low, wind protection and gloves reduce strain, and plants may need frost cover at night.
Sun and surface conditions shift comfort fast. Full sun adds radiant load, while concrete and paving can store heat and raise perceived temperature near ground level. Wet soil and grass usually feel cooler than dry soil because evaporation removes heat. If you work beside reflective walls, mulch, or metal beds, treat the result as a baseline and build in extra shade breaks.
Use the comfort band to plan tasks and pacing. In “Comfortable” and “Warm” bands, you can schedule longer sessions, but still drink water regularly. In “Hot” and “Extreme Heat,” prioritize early morning, reduce heavy digging, and watch for headache, dizziness, or unusual fatigue. In “Cool” and “Very Cold,” protect hands for tool control and consider layered clothing that can be removed as you warm up.
For repeatable decisions, save results with the CSV or PDF options. Log your inputs, comfort temperature, dew point, and VPD, then compare days and microclimates around your yard. This creates a simple record for refining irrigation timing, choosing protective clothing, and planning labor-heavy garden jobs with fewer surprises.
Comfort temperature adjusts the air reading using humidity and wind, then adds practical garden offsets for sun, surface, activity, and clothing. It is meant for planning work comfort, not for official weather reporting.
VPD indicates the drying power of air around leaves. It helps gardeners relate comfort conditions to plant transpiration and irrigation timing. Use it as context, alongside your crop needs and local guidance.
Heat index appears mainly in hot, humid conditions. Wind chill appears when air is cold and wind is strong enough to cool exposed skin. If conditions are outside those ranges, the fields stay blank.
Choose the unit you normally read on your thermometer. The calculator converts internally and returns all temperature outputs in your selected unit, so comparisons are consistent across the page and downloads.
It is an estimate based on standard comfort formulas and simple, transparent offsets. Shade, irrigation, wind breaks, and reflective surfaces can shift real comfort. Use it to compare scenarios, then adjust with experience.
Check the comfort band, then match tasks to the safest window. Do heavy digging in cooler bands, water and harvest early in hotter bands, and schedule regular shade and hydration breaks when comfort rises.
