With warm soils and the weather staying dry, there isn't much risk to soybean seed planted 2-2.5 in. If seeds need to be 3 in. deep to get to enough moisture, it is likely that, due to uneven soil moisture, some parts of the field will not come up until it rains due to uneven soil moisture and (probably) seed placement.
Weather & Climate in Western Algarve. The Western Algarve enjoys a Mediterranean climate, with hot dry summers and mild wet winters. In the summer, the heat is moderated by cooling north westerly Atlantic breezes. The region enjoys an average of over 8 hours of sunshine per day, or 3,000 hours of sunshine annually. The period from the end of May until mid-September is dry, with only 6% of the annual rainfall occurring during that period. Most of the rainfall occurs between November and February.
Winters are mild, especially in the coastal areas. Snowfall is uncommon in the Algarve; during the day it is often very pleasant and spring-like with temperatures of 15-18 degrees Celsius. The further north or the higher you travel the less pleasant winters get.
