G-Land seasonal overview
Best Surf Season (May - September)
The heart of the Indonesian dry season aligns perfectly with G-Land's prime time. During these months, the Southern Ocean pumps consistent, long-period SW groundswells into Grajagan Bay, with average heights peaking around 2.0–2.2m and periods averaging 14+ seconds. The dominant southeast trade winds (blowing from E/ESE/SE) provide near-perfect offshore conditions for the west-facing reef, keeping the waves glassy and clean. This is when the legendary barrels at Money Trees and the long left-handers come alive in all their glory. Expect firing conditions with 1.5–2.5m+ waves and light offshore breezes a high percentage of the time.
Fair Surf Season (April & October)
The shoulder months of April and October offer a slight transition. Swell heights remain solid, averaging 1.7–1.8m with long periods (13.7–13.8s), and the offshore wind consistency is still high (over 60% ideal). However, the trade winds may occasionally weaken or shift, and the swell direction can sometimes be a touch more southerly, reducing the peak power. Still, these months deliver plenty of fun, rippable waves in the 1–2m range with favorable winds – a great alternative to the peak season crowds.
Low Surf Season (November - March)
The Australian summer monsoon and the Indian Ocean's shifting weather patterns bring a noticeable decline in surf quality. From November through March, the average swell heights drop to 1.6–1.8m, and periods shorten to 12–13 seconds. More critically, the prevailing winds shift to a westerly quarter (W, WSW, SW), turning the offshore breeze into a frustrating onshore wind that chops up the faces. Ideal wind percentages plummet to 17–49%, meaning many days are blown out. While occasional south swell windows can still produce epic sessions, the consistency is nowhere near the dry season. Patience is key during these months.

Conditions at G-Land in January
January: The Monsoon Lull
January finds G-Land in the grips of the northwest monsoon. The average swell holds at 1.8m with a period of 12.3s, but the wind is ideal only 17% of the time. Swell direction is dominated by SSW (38.2%) and SW (44.1%), which is perfect for the reef, but the wind tells a different story. Westerly winds (W 36.8%, WSW 14.8%) plague the lineup, creating choppy, bumpy conditions. On the rare occasion that the wind swings to the east (E, ENE, NE), the surf can still turn on, but those windows are short-lived. Patience is required to score clean waves.
