What Does Today’s Weather Mean for Your Trip?
What should you wear today?
Wear light layers so you can adjust between warmer streets, shaded areas and the waterfront. Sun protection is also worth carrying.

Based on the current hourly forecast, the most comfortable three-hour window appears to be around 08:00–10:00. This is a forecast-based suggestion, not a guarantee.
Bosphorus conditions
The forecast does not currently show an obvious weather-related reason to avoid a Bosphorus plan, but conditions on the water can change; check your operator before departure.

Conditions may be worth checking near sunset, but sunset colour and visibility cannot be reliably guaranteed from a general forecast.
- The forecast does not currently show a high chance of rain for today.
- Temperatures are within a generally manageable range for city sightseeing if you dress in layers.

HISTORICAL CLIMATE DATA
Istanbul Weather Through the Year
This section uses official long-term Istanbul statistics from Türkiye’s State Meteorological Service (MGM), whose current Istanbul table displays a 1950–2025 measurement period. These are historical climate statistics, not the live forecast above.
Istanbul Climate Overview
Istanbul has clear seasonal changes. In the official long-term table, average monthly temperatures rise from 6.8°C in January to 24.7°C in July and August, while average monthly precipitation is lower in midsummer and higher in late autumn and winter. Day-to-day conditions can differ substantially from these long-term values, so use the live forecast for actual travel decisions.
Historical monthly humidity and wind averages are intentionally not added here because the MGM Istanbul table used by this plugin does not provide those monthly fields. For Bosphorus plans, use the live wind and rain forecast above.

Summer is the warmest and, in the official long-term table, the driest part of the year by average monthly precipitation. July and August both have a 24.7°C average temperature and 29.7°C average high. Light clothing and sun protection are useful, while the live forecast should guide decisions during hotter spells.
