Inside, at rest, no.: Forehead infrared thermometers measure the radiant heat coming from your skin. Outside in the sun, the results are skewed by the increased surface temperature being absorbed and reflected from the sunlight. The best and most accurate way to measure your temp with this kind of thermometer is inside, at rest. That temperature is more likely to accurately reflect your core internal temp.
