G’day, Rusty here. Let’s take a look at what’s ahead. I’ve got to level with you—this 16-day stretch for Irmas/Leftpoint is a total bust. There are no good surf options in the whole window, and that’s a long dry spell. Normally this spot is fairly consistent, so a blank run like this is a bit unusual, but it happens.
Water temp is 26°, right about average for this time of year.
Starting Saturday 4 July: poor surf conditions with a 30 km/h ENE cross-shore breeze. That sets the tone—ugly and lumpy.
Sunday 5 July, same deal. Winds hit 40 km/h in the morning, and the afternoon brings a 2.1m swell but it’s only 7 seconds from the ENE—short-period junk. The combined wave energy is moderate to strong, but with the wind and direction, it’s a mess.
From Monday 6 July all the way through Friday 17 July, every morning and afternoon is marked as poor surf. Winds stay ENE or NE, 30–40 km/h, cross-shore, creating lumpy cross-chop. Swell sizes range from 1ft to 2.4m, but periods are mostly 7–8 seconds, and directions are all wrong for this reef. The energy readings are between 428 and 961, but it doesn’t matter—it’s not rideable.
Saturday 18 July and Sunday 19 July ease off a bit, with swells down to 0.6m–1.3m, but still cross-shore wind and poor conditions.
No standout days. This reef needs an ESE swell and NW offshore wind, and we’re getting zero of that. With all this cross-shore wind and bumpy water, it’s looking more like a kite session than a paddle session.
Forecasts can flip—don’t lose hope.
Rusty.

Information about the Irmas/Leftpoint Surf forecast
The above surf forecast table for Irmas/Leftpoint provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Irmas/Leftpoint can be found by selecting the local surf guide option on the grey menu. Our Irmas/Leftpoint 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 (Irmas/Leftpoint) 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 Irmas/Leftpoint 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.
Irmas/Leftpoint is 15 km (9 miles) from the city of Kailua. If you plan a vacation in Oahu, look for hotels and other accommodation in Kailua. Kailua has rooms for a wide range of budgets as well as car hire and transport links.
