April: The Peak of Autumn Consistency
April is arguably the best month of the year at Gunnamatta. Average swell height is a solid 5ft (1.5m), the wave period extends to 12.5s, and ideal offshore N/NE/E winds reach 22%-the highest of any month. The swell mix is broad and powerful: SW leads at 52.0%, WSW jumps to 13.3%, and SSW adds 13.9%, giving this southwest-facing beach a nice spread of direction. SW alone contributes over 19% of observations in the 5-6.5ft and 6.5-8ft (1.5-2.5m) classes, so there is both size and quality on offer.
Wind distribution is more balanced than summer. N/NE/E offshore directions are well represented, and the post-frontal high pressure ridge often creates clean, light mornings compared with the seabreeze-dominated summer months. Westerly and NW winds still appear ahead of cold fronts, but the windows are better. Water temperature remains mild at 17.4°C, air averages 15.9°C, and rainfall increases slightly to 2.05mm/day. If you are planning a trip to Gunnamatta, April is the month to target.
