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 .
