| Name of station | I | II | III | IV | V | VI | VII | VIII | IX | X | XI | XII | Annual mean |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Lublin | −1.2 | 0.2 | 5.2 | 12.0 | 17.8 | 20.5 | 22.5 | 22.3 | 17.1 | 11.7 | 5.1 | 0.5 | 11.1 |

Scale of assessment of thermal stress of the organism according to the UTCI index
| UTCI [°C] | Thermal stress | Prevention |
|---|---|---|
| > +46 | Extreme heat stress (EHS) | Necessary periodical cooling of the organism, necessary supplementation of liquids > 0.5 l/h; avoid intensive physical activity. |
| +38 – +46 | Very strong heat stress (VSHS) | Necessary periodical use of air-conditioned rooms or shaded areas; necessary supplementation of liquids > 0.5 l/h; limit physical activity |
| +32 – +38 | Strong heat stress (SHS) | Necessary supplementation of liquids 0.25 l/h; recommended use of shaded areas, and periodical limiting of physical activity |
| +26 +32 – | Moderate heat stress (MHS) | Necessary supplementation of liquids 0.25 l/h |
| ++9 26 – | Thermoneutral zone (TZ) | Physiological thermoregulation processes are sufficient to maintain thermal comfort |
| 0 – +9 | Slight cold stress (SlCS) | Recommended use of gloves and a hat |
| −13 – 0 | Moderate cold stress (MCS) | Intensify physical activity and protect extremities and face from cold |
| −27 – −13 | Strong cold stress (SCS) | Intensify physical activity and protect extremities and face from cold; recommended increase in the thermo-isolation properties of clothing |
| −40 – −27 | Very strong cold stress (VSCS) | Intensify physical activity and protect extremities and face from cold; necessary increase in the thermo-isolation properties of clothing, and limited time spent outdoors |
| < −40 | Extreme cold stress (ECS) | Limit time spent outdoors to the necessary minimum; necessary increase in the thermo-isolation and wind-proof properties of clothing |
