The Meteorology and Hydrology Institute is predicting a chance of scattered showers Friday evening, followed by patchy fog and drizzle overnight, but from then on, it should be warm and sunny.
The showers will be more centered inland and in the east, according to a forecast issued late last night.
Saturday's temperatures will be around 24 C, slightly cooler on the islands, with light winds and partly cloudy skies.
The next day should be exactly the same, if not a notch warmer.
Looking ahead, the western islands could see light showers on Monday evening, and rainfall could step up a gear on Tuesday, although temperatures are not predicted to drop, and will remain around 15 C during nights and 25 C during the day.
