fills in: The thermal is consistent from around 3 pm. Warm midday wind is also reported for Agios Andreas, Portes and Paliochano.
Typical strength
About 13-15 knots on the summer afternoon thermal, from one session only; no citable average exists for winter frontal days.
Thermal or synoptic
thermal and frontal
The quiver, in words
Indicative, derived from the 13-15 knot afternoon thermal rather than from local rider accounts: a 75-85 kg rider wants 12-14 m on a normal summer thermal day, with a big light-wind kite or a foil paying off on the softer ones. Winter frontal days from the N or SE come in harder and pull that down toward 9-10 m. No measured local sizes.
Direction to shore
The coast here faces east into the Argolic Gulf. The SE main direction arrives side-onshore, N runs cross-shore down the long beach, and W is straight offshore, which is why west days are advanced-only. Read off the coastline rather than from a posted local rating, so check it against whoever is out before you commit to a section.
Dominant direction
SE is the main direction; N also blows and counts as a good secondary, which reconciles the N-NE reading recorded under Arcadia.

modelled
A weather model's cell over this place, not a station on it. Good for comparing places, weaker for one beach.
Modelled from the operational forecast archive at 1.5–7 km (2023-2024), daylight hours only, not a ground station: it resolves thermal, lake and valley winds far better than coarse reanalysis but still tends to understate a strong local thermal. A windy day has at least three consecutive daylight hours at 12 knots or more. The typical daily max and the direction are columns of the table above, month by month. Highlighted months are the riding season from the spot record.

The water
Type
sea
Standing depth
At Portes the bottom drops away quickly off coarse sand and pebbles, so there is little wading room and a body-drag back in is a long one. The sandy stretch north toward Paralio Astros has no depth information at all. Tide plays no part in it either way.
Tides
Tide independent.
Temperature
Summer Paralio Astros averages 23.4 C in June, 26.3 C in July and 26.8 C in August.
Winter Paralio Astros winter monthly averages are about 15.4-18.3 C, with a winter seasonal average of 16.7 C.
Wetsuit
Shorts in summer and thick wetsuit in winter; water temperatures run warm in high summer and cold in winter.

Rider tips
- Ride the empty sections away from the town swimming zones in July and August, and respect any posted riding zone.
- Skip the west-wind days unless you are advanced and have someone on shore; it is extremely strong and straight offshore.
- Check Portes when you want cleaner exposure, but expect deep water and coarse sand and pebbles underfoot.
- Ask what the day actually is before you pump: the 3 pm SE thermal, an N or NE setup, or a winter front.
- Confirm that lifeguard cover is active for your section of beach and for the season, rather than assuming it covers kiters.
- Bring a big kite for summer. A 13-15 knot thermal on a 75-85 kg rider is 12-14 m territory, and the winter fronts are the days you need the small one.
- The coast faces east, so SE is side-onshore and N runs along the beach; the coast guard number is 108.
