Skiing in the Sun Valley and North Face sectors on Mount Olympus, Cyprus.
On the slopes of Mount Olympus, Troodos ski resort combines the Sun Valley and North Face ski sectors with Cyprus’s mountain scenery. Find weather and snowfall forecasts, a meteogram, webcam imagery and maps to plan your visit.
Operation depends on snow cover and conditions. This page forecasts the Sun Valley location; compare wind and temperature and check the official piste update before travelling.

Troodos ski resort lies on the slopes of Mount Olympus, with the Sun Valley and North Face sectors. Cyprus’s winter destination for skiing and snowboarding has the Aphrodite, Hermes, Zeus and Hera lifts. Mount Olympus reaches 1,951 metres; this is the mountain summit elevation, not the height of an upper lift station.
Compare expected snowfall, temperature and wind in the detailed forecast and meteogram. Forecast fresh snowfall is not a measurement of snow depth on the pistes. Webcams provide a view of the area when their timestamps are current.
The forecast point is in Sun Valley, at approximately 1,878 m according to SRTM terrain estimates. For the settlement, see the separate Troodos village forecast.
The usual ski season runs from January to March, depending on snow cover. Before travelling, check piste and lift operation and the road conditions.
Coordinates: 34.93055, 32.86798
This is the Sun Valley forecast point, not a confirmed entrance or parking location.

Start with the 14-day weather forecast. Open the detailed tables to compare models, then explore hourly temperature, precipitation, wind and 850 hPa in the meteogram. Ensembles show the spread of possible outcomes; satellite images show observed clouds.
Available model families combine per variable. “Today” with hours in parentheses covers the stated window; subsequent days require full local coverage. Days 8–14 are less certain; missing data remain blank. Snowfall cm are fresh snow, not snow depth. Sea-level pressure. Terrain temperature downscaling by Open-Meteo; no Agios Stefanos calibration. A point forecast cannot describe every piste or assess avalanche danger. Open-Meteo

850 hPa temperature, 2 m temperature and precipitation ensembles for Weather in Troodos · Mount Olympus. Choose Open-Meteo or Direct. Auto tries Open-Meteo first, then Direct when unavailable. Direct retains the native time steps of each model; the displayed source and interval apply. Individual member availability varies by model and variable.

Satellite images and rain radarThis summary uses the destination’s fixed coordinates and the historical service’s terrain elevation. It does not change with the forecast’s manual elevation setting. Mountain terrain, wind redistribution and snowmaking are not fully represented. Snowfall days do not indicate opening days or piste snow depth.
Explore rain and snowfall frequency, monthly average daily lows and highs, and daily temperature extremes over the selected period.

Choose 10, 20 or 30 years of temperature and precipitation history. The 100-year option searches for a nearby NOAA station with a sufficiently long record; the table shows the actual coverage. NASA POWER / MERRA-2 and ERA5 provide gridded historical estimates, while NOAA GHCNd contains station observations. These sources are shown separately, not combined into one time series.
A precipitation day has at least 1 mm of total precipitation. Where a source reports rain separately, the rain-day figure covers rain alone. A snowfall day has at least 0.1 cm of fresh snow where that variable is available; it does not establish snow cover on the ground. NASA POWER does not provide snowfall here. Blank values mean missing data, not zero. Averages and extremes use only the complete months or years stated in the table. These historical figures do not automatically calibrate the forecast.

The blend uses the values available for each day and variable. Coverage falls as individual models reach their forecast limits. The two IFS products are not independent models. Model spread shows disagreement, not the probability of a weather event.
Wind: maximum daily speed at 10 m and prevailing direction of origin. Direction uses a speed-weighted circular calculation; missing or strongly opposing directions display a dash. 🥶: low below 0°C. 🥵: high above 30°C. 💨 in Conditions: wind at least 40 km/h or gusts at least 60 km/h.

The choice applies to widgets, maps and forecasts. Actual station readings stay unchanged. Automatic tries Open-Meteo first, then available direct sources if a supported request fails.
Data service providing forecasts from NOAA, ECMWF, ECCC, DWD, the Met Office, Météo-France and JMA. Available models, variables and grids depend on the location and product.
XIONIA collects data directly from the model providers. Forecasts and maps are served after the source cycle has been published and collected. The selected product shows its model, resolution, available variables and run.
Each available family contributes once per variable. Direct forecasts select the freshest available GFS grid and use equal family weights as the baseline. Local weights apply only where enabled after validation. The comparison shows actual percentages and model cycles.
Additional model forecasts are also shown for comparison and backtesting. Their presence does not automatically add weight to the combined forecast; check the displayed weights.
A dash means unavailable data. Wind and gust may use different models. AIGFS temperature is excluded when it cannot be compared on the same elevation basis. Six-hour precipitation is water equivalent, not snow depth.
A “Today” label with hours in parentheses covers only the stated time window; subsequent days require full local coverage. Days 8–14 are a less certain outlook. Agreement between models is not a probability from a true ensemble.
Ensemble systems provide multiple forecast scenarios; the available systems appear in the chart selector and image catalogue. AIGFS is the single forecast; AIGEFS is the separate ensemble. Available variables and forecast horizons differ by system.

The forecast point for Troodos · Mount Olympus is at 1,878 m (Troodos · 34.930550°, 32.867980°).
Use the daily forecast to compare fresh snow, temperature and wind. The mountain view shows the selected day and model; XIONIA’s combined forecast is selected initially. Fresh snowfall and snow already on the ground are separate measurements. Snowfall elevation is a model value or a labelled approximate estimate when available. Days 8–14 show a less certain trend.
The forecast refers to this point; conditions on the summit and at the ski base can differ. Check the resort operator for lift and piste status.
