Krishna River seasonal overview
Best Surf Season (October - December)
October is where it all starts to click at Krishna River. As the Southwest Monsoon retreats and the Northeast Monsoon builds into the Bay of Bengal, the persistent onshore S and SSW winds fade and the coast switches to cleaner, more cross-offshore flows from the N, NNE, NW and NNW. Ideal wind frequency jumps to 37 percent in October and peaks around 46 percent in November, while average wave periods sit in the 8-9 second range and heights hover near 1-1.1m (3-4ft). October still carries plenty of optimal SSE groundswell before the swell direction shifts more easterly in November and December. It is not the biggest surf of the year, but the surface texture improves dramatically and the river-mouth sandbars start to hold shape. For the best combination of wave size, swell direction and clean wind, October is the standout month.
Fair Surf Season (January - February and August - September)
January and February offer the tail end of the Northeast Monsoon. Swell direction becomes more SE/SSE, which lines up well with the beach, but winds turn increasingly onshore from SSE and S, dropping ideal wind frequency to 19 percent in January and just 7 percent in February. August and September are the other fair window: active monsoon lows in the Bay of Bengal send consistent S/SW swell with average heights of 1.1-1.3m (4ft) and periods up to 9.5s, but WSW/SW winds still dominate. However, ideal wind chances rise to 19-23 percent, so there are more legitimate clean session windows than in mid-monsoon, especially when the wind backs to the NW.
Low Surf Season (March - July)
From March through July, the onshore trade wind and monsoon machine takes over. Ideal wind frequency collapses to just 1 percent in March and April and remains below 11 percent until August. Although the ocean produces plenty of SSE, S and SSW swell from April onward, and June/July average 1.3m (4ft) with longer-period energy, the wind is almost always blowing from S, SSE, SSW or SW. That piles the Krishna River mouth with bumpy, lumpy, sectiony surf. The late spring and early summer months are best avoided unless you are chasing a rare N/NW wind window after a passing low-pressure system or a tropical disturbance.
