The Lowdown
Alright mates, Rusty again. Let’s cut to it: the next two weeks at Maenporth offer zip for surfing. From Friday July 17th all the way through Saturday August 1st, every single forecast slot says “poor surf conditions.” Not a single rideable wave in sight.
Maenporth is a sheltered, inconsistent beginner break, so a blank spell like this is pretty normal. The water temperature on the 17th is 18° – that’s about 2° warmer than usual for the time of year, so it’s comfortable for a swim, but there’s just no swell. The only blip is Sunday the 19th afternoon: a 1.0m easterly swell with a 5‑second period and combined energy of 111 – still weak, short‑period dribble, and the wind is light cross‑shore. The optimum swell direction for Maenporth is SSE; this easterly stuff doesn’t suit it. All other days have waves under 0.5m, often 0.1m or flat. Winds sometimes go clean offshore, like Wednesday the 22nd morning with 25 km/h offshore, but with 0.1m of swell you’re not catching anything.
Save the petrol. Unless you fancy a flat‑calm float, there’s no surf to be had. Could always change, but right now it’s a total bust.
Rusty.

Information about the Maenporth Surf forecast
The above surf forecast table for Maenporth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Maenporth can be found by selecting the local surf guide option on the grey menu. Our Maenporth surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Maenporth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Maenporth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
