Is today good for surfing? Check the Weather First
Surfing is the most weather-dependent sport on the planet — wind direction, swell, tide, and water temperature all have to align. Use this guide to learn the rules pros use to read a forecast, then check the score above to see if today is worth waxing the board.
The Three Numbers Every Surfer Reads First
Before checking anything else, experienced surfers look at three numbers: swell height, swell period, and wind direction. Swell height (in metres or feet) tells you how big the waves will be, but height alone is misleading. A 1.5m swell at 14 seconds period delivers powerful, well-formed waves that break with authority — that is solid head-high surf for an average rider. The same 1.5m height at 7 seconds period is mushy, weak windswell that closes out and barely lets you stand up. As a rule of thumb, period below 8 seconds is local windswell (short, choppy, low energy), 9–13 seconds is mid-range groundswell (the daily bread of most surf spots), and 14+ seconds is long-period groundswell from a distant storm — the same 1m reading can produce double-overhead bombs at exposed reefs. Wind direction is the third pillar: offshore wind (blowing from land out to sea) holds the wave face up, grooms it smooth, and creates the hollow, photogenic conditions surfers chase. Onshore wind (sea to land) flattens the face, creates chop, and turns even a perfect swell into mush. Cross-shore is workable but rarely magical. Match those three numbers and you have a surfable forecast — miss any one and the day is wasted.
Wind Speed Rules of Thumb
Wind speed is just as important as direction. Light offshore winds of 5–15 km/h are ideal — strong enough to clean up the face, gentle enough not to slow incoming waves down or blow you off the back. Offshore winds above 25 km/h start working against you: they hold up the lip so long that waves break late and slabby, spray blinds you on takeoff, and paddling into anything becomes an arm-burner. Onshore winds tell a similar story in reverse. Below 10 km/h onshore is annoying but ridable; 10–20 km/h produces choppy, victory-at-sea conditions where only beach breaks at high tide hold shape; above 25 km/h onshore, give up and check the forecast for tomorrow. The best surfers track wind forecasts hour by hour because conditions can flip from glassy dawn to blown-out by 10am, especially in summer when daytime heating creates a strong onshore sea breeze. The dawn patrol exists for a reason — pre-sunrise winds are almost always lightest, and the surface is often glassy regardless of swell direction.
Tide, Swell Direction, and Why "Today Was Firing" Is Personal
Two surfers can stand on the same beach on the same day and disagree completely about conditions, because every break has a tide and swell-direction sweet spot. Reef breaks often need mid-to-high tide so waves do not break on dry rock; many beach breaks prefer mid tide for the cleanest sandbars; some shallow points only work at high tide. Swell direction matters even more — a south-facing beach is dead during a north swell, no matter how big the buoy reading. Local knowledge always beats raw numbers, and that is why the same forecast generates a "10/10" score at one spot and a "skip it" at the spot ten kilometres down the coast. Use this page to filter out the obvious no-go days (storms, blown-out wind, freezing water without a wetsuit), then cross-check with a local surf cam or report before paddling out. Our score weighs wind, precipitation, and temperature — the universal factors — but not the swell-vs-spot orientation, which is genuinely local intelligence.
Key Weather Factors for Surfing
The single most important factor for wave shape — offshore grooms the face, onshore destroys it
Ideal: Light offshore (blowing from land to sea) at 5–15 km/h
Even the right direction becomes a problem at high speeds
Ideal: Under 20 km/h offshore, under 10 km/h onshore
Time between wave crests — determines wave power and shape more than height
Ideal: 10–16 seconds for clean groundswell; 7–9s is windswell, mushy
Wave size at the buoy — needs to be combined with period and spot exposure
Ideal: 0.8–1.5m for beginners, 1.5–2.5m for intermediate, 2.5m+ for experienced
Determines wetsuit thickness and session length
Ideal: 20°C+ for boardshorts, 15–20°C spring suit, 10–15°C 4/3mm full suit
Heavy rain washes pollution and runoff into coastal waters — wait 24–48h after major storms in urban areas
Ideal: No active rain; dry for 48h near city beaches
Seasonal Surfing Guide
Winter (Dec–Feb, Northern Hemisphere)
Prime season for most North Atlantic, North Pacific, and Mediterranean surf. Storm systems generate consistent groundswell. Expect cold water (often 8–14°C) — a 4/3mm or 5/4mm wetsuit, hood, booties, and gloves are mandatory. Sessions are shorter but waves are biggest and most powerful of the year.
Spring (Mar–May)
Transition season with mixed swells and warming water. Sea breezes start to build in the afternoons — dawn patrol becomes essential. Crowd levels rise as conditions improve. Good window for intermediate surfers wanting size without the brutal cold of midwinter.
Summer (Jun–Aug, Northern Hemisphere)
Smallest and most inconsistent swell of the year in most temperate zones, but warmest water (often 18–24°C — boardshorts or springsuit weather). Best for beginners learning on small, gentle days. Tropical regions and the Southern Hemisphere flip this — Indonesia, Australia, and South Africa peak from May–September.
Autumn (Sep–Nov)
Widely regarded as the best season for experienced surfers in the Northern Hemisphere. Hurricane and typhoon season pumps long-period groundswell into exposed coasts, water is still warm from summer, sea breezes weaken, and tourist crowds thin out. Track tropical cyclone forecasts for swell windows.
Safety Tips
- Never surf alone in unfamiliar waters — rip currents, hidden rocks, and sudden swell spikes catch even experienced surfers off guard
- Check the tide chart before paddling out: many reef and point breaks become unrideable or dangerous at low tide
- Wait 24–48 hours after heavy rainfall to surf near urban beaches — runoff carries bacteria, sewage, and debris that cause infections
- Learn to spot rip currents: darker water moving seaward, channels of calm between breaking waves, foam or debris drifting offshore. If caught, paddle parallel to shore, not against the current
- Cold-water hypothermia sets in faster than you expect — limit sessions to 60–90 minutes in water below 12°C, even with a thick suit, and warm up immediately on exit
- Lightning over the ocean is lethal — exit the water at the first thunderclap and wait at least 30 minutes after the last strike before paddling back out
Surfing Gear Checklist
- Wetsuit matched to water temperature: 2mm spring (18–22°C), 3/2mm full (15–18°C), 4/3mm + booties (10–15°C), 5/4mm + hood + gloves (under 10°C)
- Surfboard appropriate for conditions and skill — bigger and longer for small/weak days, shorter and more rocker for powerful surf
- Leash matched to board length plus 30cm, in good condition (a snapped leash in heavy surf is dangerous)
- Wax for current water temperature (cold-water wax in winter, tropical wax above 24°C — the wrong wax slides off)
- Reef booties for rocky or urchin-prone breaks; surf earplugs to prevent surfer's ear from cold water exposure
Frequently Asked Questions
What does "offshore wind" mean and why does it matter so much?
Offshore wind blows from the land out to sea, directly into the face of incoming waves. It holds the wave face vertical, smooths out chop, and creates the hollow, glassy conditions you see in surf magazines. Onshore wind (sea to land) blows from behind the wave, flattening the face and creating mush. Offshore is so important that surfers will drive hours to find a coastline that faces the right direction on a given day. Light offshore (5–15 km/h) is ideal; above 25 km/h offshore actually starts to work against you by holding the lip up so long the wave breaks late.
What swell period is good for surfing?
Swell period — the seconds between wave crests at the buoy — matters more than height. Period under 8 seconds is local windswell: short, weak, choppy, often closes out. 9–13 seconds is mid-range groundswell, the daily bread of most surf spots. 14+ seconds is long-period groundswell from a distant storm; the same 1m height reading at 16 seconds can produce double-overhead waves at exposed reefs because the energy is much deeper in the water column. As a rule, multiply height by period and you get a rough sense of the day's power.
When is the best season to surf?
It depends on your hemisphere and skill level. In the Northern Hemisphere, autumn (September–November) is widely considered the best window: long-period groundswell from hurricanes, water still warm from summer, light winds, fewer crowds. Winter (December–February) brings the biggest and most consistent waves but coldest water — bring a 4/3mm suit minimum. Summer is smallest and best for beginners. The Southern Hemisphere flips this: Indonesia, Bali, and Western Australia peak from May to September during the southern winter swell season.
Is it safe to surf in the rain?
Light rain is fine and often comes with great waves (storm-front conditions). Heavy rain is a different story — and not because of the rain itself, but because of urban runoff. After a heavy downpour in any city beach, stormwater carries oil, bacteria, and sewage into the lineup; surfing within 24–48 hours of a major rain event in urban areas is a documented infection risk (ear, eye, gastrointestinal). Lightning is a separate, immediate hazard: get out of the water at the first thunderclap and stay out for at least 30 minutes after the last strike.
How big is too big for an intermediate surfer?
A reasonable rule for intermediate surfers (1–3 years experience, comfortable on shoulder-high waves) is to stop at chest- to head-high (around 1.5m face height) on any day with strong onshore wind, and head-high on clean offshore days. The bigger limit is paddle power and hold-down tolerance, not wave size in isolation. A 2m swell at 16 seconds period is genuinely advanced surf at most beach breaks — long hold-downs, powerful currents, and hard-breaking sets. If you cannot duck-dive every wave on the paddle out, the day is too big for you. Always check a local surf cam before driving to the beach.
