The Lowdown
Rusty here, checking in from the Cornish coast. It's a flat spell we're looking at, I won't beat around the bush. For the next 16 days, there's nothing in the Maenporth zone that's going to have you rushing for your wetsuit. The whole period is a write-off for decent waves.
We start off with a handful of clean mornings thanks to a gentle offshore breeze. Sunday the 9th has clear skies and a light northwesterly, but the swell is a tiny 0.7 ft from the west-southwest with a short period of 6 seconds. The wave energy is a pathetic 7, so it's a total non-event. Monday the 10th brings the swell up to 1 ft, still with a poor period and only 18 units of energy. The winds stay favourable, but there's just no power behind the waves.
As we get into Tuesday the 11th, the wind swings to an onshore direction from the east-southeast, adding some chop to the already tiny waves. The surf stays minimal right through until the end of the forecast window. There's a glimmer of something on Wednesday the 12th morning, with a 3 ft swell from the west-southwest and a longer period of 10 seconds. The combined energy hits 197, which is the highest we'll see. But the wind is cross-onshore and the conditions are still rated as poor. It's a tease.
For the remainder of the second week and into the third, the swell drops away to a mere 0.3 ft or flat. The water is currently 66°, which is a touch warmer than usual for this time of year, but that's small comfort. There's simply no surf to be had.
It’s a dry spell, plain and simple. Keep an eye on the long-range, but for now, it’s a good time to wash the wax off your board.
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.
