Conditions at Tiruchendur in April
April: Long-Period South Swell, But Poor Direction
April is the pre-monsoon transition, and the character of the surf changes quickly. The swell window rotates away from the east and becomes dominated by S (62%) and SSW (11%) swell, with SSE (23%) still offering the only favorable angle for the SE-facing beach. The average period reaches 12.1s, making this the most powerful swell window of the year, but the height remains small, averaging 0.8m (2.5ft). Wind conditions become increasingly SW/SSW, with the combined SW/SSW/WSW total near 50 percent. That is not the onshore direction listed as worst for the spot, but it is far from the clean offshore W/NW flow. When the wind does go light, the long-period S/SSW groundswell can wrap in and produce clean, hollow shoulders. Water temperature peaks at 30.6°C and air temps are hot, with rain beginning to build (2.4mm/day).
