Conditions at Caldera in June
June: Southern Hemisphere Pulse, Onshore Bias
June continues the peak of the SSW/SW swell season. The average period is 14.5s, and the combined SSW (72.8%) and SW (16.4%) signal is over 89%, meaning nearly all of the swell is arriving from the exposed southern quadrants. In theory, this should be prime time for Caldera. Yet the height data are brutal: average swell height is around 1ft (0.3m), with only 0.7% of the month in the 2-3ft (0.5-1m) range. The wind regime is mostly southerly as well, with S at 15.1%, SSW at 12.9% and SSE at 11.1%, while offshore NNE/NE/ENE/E flow drops to around 23%. Rain is frequent at 5.36mm/day and water temperature is 29.3°C. The period and direction are there, but the Southern Hemisphere storm track simply is not delivering enough size to this corner of Costa Rica.
