Conditions at Tywyn in July
July: The Peak of the Summer Slump
July is the lowest point of Tywyn's surf calendar. The average swell height remains at 1.6ft (0.5m), while the average period compresses to just 6.0s - the shortest of the year. WSW dominates the swell rose at 43.8 percent, with SW, W, WNW and NW contributing the majority of the remaining energy, but over 80 percent of all observations are below 1m. Larger waves are almost nonexistent; only about 1 percent of the month sees 5ft (1.5m) or more. This is choppy, messy, low-energy surf unless you are chasing whitewater on a soft top.
The wind data are equally discouraging. Ideal offshore wind conditions occur just 2 percent of the time, the lowest in any month, while onshore flow from SW, WSW, W and WNW makes up around 47 percent of the wind rose. Persistent sea breezes and Atlantic westerlies keep the surface lumpy. The saving graces are summer warmth: air temperatures average 15.2°C, water temp warms to 16.8°C, and 2.45 mm/day of rain keeps the hills green. For a dedicated surfer, July is a holiday, not a swell-chasing mission.
