2. Bioclimatic chart for Irbid
Bioclimatic analysis is a systematic procedure for the assessment of thermal comfort in
relation to external climate. It has the purpose of identifying desirable adaptations of
structure to meet human comfort needs under specific climatological conditions.
Tempreture:
The monthly mean minimum and maximum daily temperature
Relative humidity:
This is the mean monthly relative humidity

3. Irbid,
Irbid has a hot mediterranean/ dry-summer subtropical climate (Köppen-Geiger
classification: Csa) that is mild with moderate seasonality. Summers are dry and hot due
to the domination of subtropical high pressure systems while winters experience
moderate temperatures and changeable, rainy weather due to the polar front. These
climates usually occur on the western sides of continents between the latitudes of 30°
and 45°. Vegetation is adapted to the dry summers and is fragrant and oily making it
susceptible to fire. The typical Mediterranean climate average monthly temperatures in
excess of 22.0 °C (71.6 °F) in its warmest month and an average in the coldest month
between 18 to -3 °C (64 to 27 °F) with at least four months above 10 °C (50 °F).
Seasonality is moderate .
According to the Holdridge life zones system of bioclimatic classification Irbid is situated
in or near the subtropical thorn woodland biome.
✓ The mean annual temperature is 17.5 degrees Celsius (63.5 degrees Fahrenheit).
✓ Average monthly temperatures vary by 16.5 °C (29.7°F).
✓ Total annual Precipitation averages 475 mm (18.7 inches) which is equivalent to
475 Litres/m² (11.65 Gallons/ft²
conclusion...
✓ Hot season / summer is in June, July, August and September.
✓ Most rainfall (rainy season) is seen in September.
✓ Irbid has dry periods in April, May, June and July.
✓ On average, the warmest month is August.
✓ On average, the coolest month is January.
