When purchasing property in Israel, one crucial factor that significantly impacts your living experience is the direction your apartment or house faces. The orientation affects natural light, prevailing winds, temperature regulation, and overall comfort throughout Israel’s diverse climate zones. With electricity costs in Israel being notably high compared to many Western countries, optimizing your home’s orientation can lead to substantial long-term savings. This comprehensive guide will help you understand the advantages and disadvantages of different air directions in the Israeli context.
Why Air Direction Matters in Israel
Israel’s Mediterranean climate features hot, dry summers (May to October) with temperatures regularly exceeding 30°C (86°F) and mild, rainy winters (November to April) with temperatures typically between 10-20°C (50-68°F). However, the country’s diverse topography creates distinctive microclimates across regions:
- Coastal Plain: Humid subtropical climate with summer temperatures moderated by sea breezes but high humidity (60-80%)
- Central Highlands: Mediterranean climate with more extreme temperature variations and lower humidity
- Jordan Valley: Hot desert climate with summer temperatures frequently exceeding 40°C (104°F)
- Negev Desert: Arid climate with extreme day-night temperature fluctuations (often 20°C/36°F difference)
- Galilee Highlands: Cooler temperatures year-round with occasional snow in winter
Understanding air direction in these diverse contexts can help you:
- Optimize natural cooling and heating through passive design principles
- Reduce energy costs (electricity prices in Israel average 0.50-0.65 NIS per kWh)
- Maximize natural light while minimizing glare and heat gain
- Enhance living comfort year-round considering Israel’s 3,000+ hours of sunshine annually
- Make informed property investment decisions that affect long-term value
- Adapt to Israel’s specific climate challenges including hamsin/sharav events (hot, dry desert winds)
The Most Desirable Air Directions in Israel
Western Direction (Facing the Mediterranean)
Advantages:

- Special consideration: One of Israel’s hottest regions; cooling is the primary concern with AC running 7-9 months yearly
- Elevation factor: Properties at -400m below sea level experience higher atmospheric pressure and approximately 10% more oxygen
- Humidity considerations: Despite desert conditions, proximity to water bodies creates humidity pockets (30-60%)
- Unique adaption needs: UV protection is critical with radiation levels 5-10% higher than coastal areas due to lower elevation
- Traditional building orientation: Historical settlements in the region consistently oriented openings north and east
Haifa and Northern Coastal Areas
- Optimal direction: Western and southwestern to capture sea breezes while benefiting from Mount Carmel’s shade in late afternoon
- Second-best direction: Southern for balanced light and moderate temperatures
- Challenging direction: Eastern in summer (hot winds off the Galilee); northern in winter (cold winds)
- Special consideration: Haifa’s unique topography (built on Mount Carmel slopes) creates distinct microclimates between lower and upper city
- Lower city (Hadar, Downtown): Warmer with more humidity (65-85%) and stronger sea influence
- Upper city (Carmel neighborhoods): 2-4°C cooler with lower humidity (55-75%) and more mountain breezes
- Elevation gradient: Temperature decreases approximately 2-3°C from sea level to the top neighborhoods at 400m elevation
- Seasonal wind patterns: Winter northeasters can be particularly strong in Haifa Bay area (25-40 km/h)
Practical Tips When Evaluating Property Air Direction
- Visit at different times of day: Experience the property’s light and temperature changes throughout the day. Ideally, view properties:
- In the morning (8-10am) to assess eastern exposure
- At midday (12-2pm) to assess southern exposure
- In the afternoon (4-6pm) to assess western exposure
- If possible, visit once during summer and once during winter for a complete picture
- Consider seasonal variations: What works in summer may be less ideal in winter, and vice versa.
- Summer priorities: Cross-ventilation, shading options, northern/eastern exposure for bedrooms
- Winter priorities: Insulation quality, southern exposure for common areas, protection from prevailing winter winds
- Remember that Israel’s summer (May-October) lasts longer than winter, affecting the weight given to each season’s considerations
- Evaluate surrounding buildings: Nearby structures can block desirable breezes or provide unwanted shade.
- Buildings within 50 meters can significantly impact airflow
- In Tel Aviv’s dense neighborhoods, upper floors (4+) receive substantially more breeze than lower floors
- Check municipal building plans (taba) for future construction that might block views or breezes
- Consider the height and distance of surrounding buildings using the “45-degree rule” (unobstructed light if neighboring buildings are at less than a 45-degree angle from your windows)
- Assess window placement: The size and position of windows greatly affect how air direction impacts the interior.
- Israeli building standards typically allocate window area equal to at least 12-15% of floor area
- Check for “hamam” windows (high, small windows typical in bathrooms/stairwells) that affect ventilation
- Note the presence of mamad (reinforced security room) windows, which are smaller and affect airflow
- Measure window sizes: Small windows (<1m²) limit both light and ventilation regardless of direction
- Balance with other priorities: Location, price, and layout might outweigh perfect air direction.

- Ensure adequate shading for western windows to prevent overheating
- Consider floor height—higher floors benefit more from cooling breezes
For Jerusalem and mountainous regions:
- Balance southern exposure for winter warmth with cooling solutions for summer
- Eastern exposure works well for morning-focused households
- Pay special attention to winter heating efficiency in northern-facing properties
For desert regions (Negev, Arava):
- Prioritize northern exposure to minimize heat gain
- Look for properties with significant thermal mass (stone, concrete) to moderate temperature swings
- Consider traditional desert design principles like narrow streets, courtyards, and minimal western exposure
