All About Crete Weather. Weather in Sitia/Siteia. This detailed 10 Day Weather Forecast in Crete for Sitia/Siteia, Lassithi Prefecture is prepared for the local ex-pat residents and holidaymakers. The delight of Sitia (Greek: Σητεία) is that it has welcomed tourism for many years yet visitors have yet to overwhelm it. It is as relaxed and laid back as ever. Sitia is the centre of wine and the olive oil industries as well as being the gateway to Crete's most Eastern part. Sitia Airport takes on a new lease of life with the arrival in May 2012 of the first regular charter flights. Arkefly will fly into Sitia from Amsterdam Schiphol. Holiday Weather Tip: Sitia is part of the driest area of Crete. The climate there is more closely linked to that of North Africa than Europe - in common with the lowlands of the South Crete coastline. That means long dry sunny periods with clear bright days in which to explore this lightly populated part of Lasithi prefecture.
