I am still doing research on the weather history of Algeria
“Northern Algeria is within the temperate zone, and has a climate similar to other Mediterranean countries. The diversity of the topography can produce a sharp contrast in temperature. Along the coastal region, the climate is pleasant climate, with winter temperatures averaging from 50° to 54° F (10° to 12° C) and average summer temperatures ranging from 75° to 79° F (24° to 26° C). Rainfall in this region is abundant, averaging 15 to 27 in (38 to 69 cm) per year, and up to 40 in (100 cm ) in the eastern part. Oran is an exception to this treand due to a mountain barrier against rain-carrying winds. When heavy rains fall, large areas cab become flooded and then evaporate so quickly that they are of little help in cultivation.”
“Farther inland from the Mediterranean, the climate changes; winters average 39° - 43° F (4° to 6° C) , with considerable frost and occasional snow on the massifs ( section of a planet's crust that is demarcated by faults or flexures) summers average 79° to 82° F ( 26° to 28° C). In this part of the country the, prevailing winds are westerly and northerly in winter and easterly and northeasterly in summer, resulting in a general increase in precipitation from September to December and a decrease from January to August. There is little or no rainfall in the summer months.”
“In the Sahara Desert, temperatures range from 14° to 93° F ( -10° to 34° C ), with extreme highs of 120° F ( 49° C ), with daily variations of more than 80° F ( 44° C ). Winds are frequent and violent. Rainfall is irregular and unevenly distributed.”
