Conditions at Marinaretti in April
April: Spring Lull - Morning Windows Only
April is the first true shoulder month. The average swell height is still listed at 2-3ft (0.8m), but periods drop to just 5.2s, revealing a shorter-period, less organized windswell. The preferred S/SSW/SW quadrant accounts for a respectable 28% of the wave rose, yet only about 5% of the total time produces waves over 3ft (1m) from those directions. There is surf, but it demands a groveler and good timing.
The wind deck is also shifting: offshore flow now sits near 20%, among the lowest of the year so far, while ESE and SE sea breezes combine for nearly 20% of the wind distribution. Air temperature rises to 14.5°C and water temp to 15.5°C, but rain is still around 2.24mm/day. Look for pre-frontal southwesterly pulses and clean N/NW winds in the early morning; afternoons are mostly softened by cross-shore and onshore thermal wind.
