Seasonal Trading Considerations

Winter (December - February): Warm with highs 28-30�C (82-86�F). The most pleasant season. Occasional light rain.

Spring (March - May): Rapidly warming. Dust storms possible from the interior.

Summer (June - September): Extremely hot with highs 38-42�C (100-108�F). High humidity makes conditions oppressive.

Autumn (October - November): Gradually cooling but still very warm.

Trading Tips for Jeddah

Jeddah's Red Sea location creates high humidity that makes the heat index significantly higher than the actual temperature.

Interior desert heat waves can push temperatures even higher than normal.

Dust storms from the Arabian Desert can affect visibility and temperatures.

The narrow seasonal temperature range means most variation occurs within daily cycles.
