Conditions at Streedagh Strand in July
July: The Summer Flat Spell
July is the least consistent month of the year for real surf at Streedagh Strand. The average swell height is just 2.5ft (0.8m) and the average period bottoms out at 8.5 seconds. The swell rose still points relentlessly at the WNW with 34.6 percent, but the heights are mostly confined to the 2-3ft (0.5-1m) range. There are occasional 3-5ft (1-1.5m) pulses from passing summer lows, but they are the exception rather than the rule.
Wind-wise, July is the most onshore month. The W/NW/NNW quadrant together accounts for over 40 percent of all wind, and the ideal southeast-to-east offshore flow only appears around 15-17 percent of the time. The clean surf percentage is just 17 percent, the lowest of the year. Water temperature reaches its warmest at 15.4°C and air temperatures average 14.8°C, so for swimming, SUP and small-wave logging it is lovely; for serious surfing it is a patience game. Precipitation averages 3.26 mm/day.
