Conditions at Kastro Point in July
July: High Summer, Flat Horizons
July is the lowest-energy month of the year alongside August. The average swell height is 0.4m (1.3ft), the period is 4.2s, and surfable south-quadrant swell falls to only 1.8%. The swell rose is almost laughably dominated by WNW (48.3%) and NW (18.1%), almost all of it under 0.5m. The wind story is more interesting: the meltemi blows from the NW/NNW with notable consistency, giving Kastro its most frequent offshore wind of the year (ideal conditions 18% of the time). But without groundswell, that offshore wind just polishes a lake. Air temperatures bake at 26.0°C, water temperature reaches 23.4°C, and precipitation is minimal at 0.45 mm/day. If you are a beginner, the small clean summer rollers can be playful, but for most surfers July is a write-off at Kastro Point.
