The Lowdown
Alright, folks, Rusty here again. Let's talk Tennis Courts in feet and degrees. It's a reef break, exposed, and the best swell comes from the SSE. Water's 81°, right where it should be for this time of year.
We're starting off real slow. Sunday the 13th has tiny 2ft SW swell with a 15-second period, but that ENE cross-off wind at 15 km/h and combined energy of 133 makes it a "poor" call. Not worth the wet suit. Monday and Tuesday (14th and 15th) are just as small – 1.0ft to 2ft – same cross-off wind, marginal conditions. Energy picks up a bit (438 by Tuesday morning) but the swell direction is SW, not the optimum SSE.
Wednesday the 16th sees 3ft SW swell with an 18-second period – that's groundswell. Energy is 563, but the wind is 30 km/h from the ENE. It's cross-off, so the face might be clean, but it's still marginal.
Thursday the 17th gets wild: 7ft from the ENE with a 7-second period – total wind chop. Energy is 941, moderate, but with that short period and 35 km/h wind, it's a mess. This is kite-surfing territory, not paddle surfing. Friday the 18th, swell drops to 3ft from the SSW, period 17 seconds, energy 1216. Still cross-off wind, still marginal.
Saturday the 19th has 6ft ENE windswell (8-second period), energy around 866-940. Another washout. Sunday the 20th is worse: 7ft ENE, 7 seconds, 931 energy, "poor" conditions. The pattern holds: a lot of 5ft to 8ft ENE swell with short periods (7-13 seconds) and strong 30-35 km/h cross-off wind. Energy values are moderate to strong (500-1497), but the wind and period aren't giving us quality.
The best window is Tuesday 22nd afternoon to Thursday 24th. Tuesday 22nd afternoon has 6ft ENE swell with a 13-second period, energy 1497 – that's strong. Still cross-off wind at 30 km/h, but the longer period means more organised swell. Wednesday 23rd has 8ft to 8ft ENE swell, period 10-11 seconds, energy 1441. That's big – over 8ft is expert-only. The wind is fresh, so not clean, but the power is there. Thursday 24th is similar: 8ft ENE, 9-second period, energy 1162-1107. For the advanced crew only.
After that, it fades. Friday 25th to Sunday 27th has 6ft to 7ft ENE swell with short 7-8 second periods and dropping energy (636-756). Poor to marginal. Monday 28th brings a change: 3ft SSW swell, 17-second period, energy 942, and lighter 25 km/h wind. Still cross-off, but the longer period could help.
The standout is that Tuesday 22nd afternoon to Thursday 24th window. Solid 6ft to 8ft swell with longer periods (10-13 seconds) and strong energy (over 1100). But that ENE wind is a constant problem – cross-off isn't ideal, and with these sizes, it's for experts only. The direction is ENE, not the optimum SSE, so it's not hitting the reef perfectly.
Crowds can pop up sometimes, and with this much energy, there'll be a few out. But with the wind and direction not cooperating, it's not the classic session.
If you're game, aim for Tuesday 22nd afternoon through Thursday 24th. The first week is mostly a bust, with only marginal options from Wednesday 16th. The second week has the most potential, but it's a promise, not a lock. After that, it fades again.
Rusty out.

Information about the Tennis Courts Surf forecast
The above surf forecast table for Tennis Courts provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tennis Courts can be found by selecting the local surf guide option on the grey menu. Our Tennis Courts 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 (Tennis Courts) 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 Tennis Courts 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.
Tennis Courts is 4 km (2 miles) from Honolulu. If you plan a vacation in Oahu, look for hotels and other accommodation in Honolulu. Honolulu has rooms for a wide range of budgets as well as car hire and transport links.
