Conditions at St Ives in June
June: Summer Slumber
June sees summer settle in over St Ives. Average swell height bottoms out around 1.2m (4ft), with average period falling to 8.7s - choppy, low and messy on a regular basis. The swell rose is bloated with W (31.5%) and WSW (21.3%) energy, but most of it is short-period windswell in the 0.5-1.5m range; there are just enough 1.5-2m pulses to keep hope alive. WNW (13.1%) remains the most favorable swell direction, but the overall lack of power keeps wave quality marginal. Winds are lighter overall, yet NNW (12.2%) is the most common wind direction - straight onshore for this exposed north-northwest beach. Still, with WSW (10.1%), SW (9.0%) and SSW (6.9%) in the mix, there are morning windows where offshore winds groom the smaller swell into clean, fun-size waves. Ideal conditions are 19%. Water temps rise to 14.4°C, air temps average 14.3°C and rain remains modest. It is not the month to expect barrels, but a longboard will be your best friend.
