Summers are hot and dry, due to the domination of the subtropical high pressure systems, except in the immediate coastal areas, where summers are milder due to the nearby presence of cold ocean currents that may bring [[fog]] but prevent rain.<ref name=McKnight />{{rp|221–3}}

=== {{anchor|Csb}}''Csb'': Mediterranean warm/cool summer climates ===
Dry-summer climates sometimes extend to additional areas (sometimes well north or south of) typical Mediterranean climates, however since their warmest month average temperatures do not reach {{convert|22|C|1}} they are classified as ''Csb''.<ref name=Beck /> Some of these areas would border the [[oceanic climate]] (''Cfb''), except their dry-summer patterns meet Köppen's ''Cs'' minimum thresholds.

=== {{anchor|Csc}}''Csc'': Mediterranean cold summer climates ===
Cold summer Mediterranean climates (''Csc'') exist in high-elevation areas adjacent to coastal ''Csb'' climate areas, where the strong maritime influence prevents the average winter monthly temperature from dropping below 0&nbsp;°C. This climate is rare and is predominantly found in climate fringes and isolated areas of the Cascades and Andes Mountains, as the dry-summer climate extends further poleward in the Americas than elsewhere.<ref name="McKnight" /> Rare instances of this climate can be found in some coastal locations in the North Atlantic and at high altitudes in Hawaii.

* [[Balmaceda, Chile|Balmaceda]], [[Chile]] (''Csc'')

* [[Harstad]], [[Norway]] (''Csc''), alternatively: dry-summer subarctic climate (''Dsc'')
* [[Liawenee]], [[Australia]] (''Csc, bordering on Csb'')
